Pytest 3.6.2 (2018-06-20)
=========================
Bug Fixes
---------
- Fix regression in ``Node.add_marker`` by extracting the mark object of a
``MarkDecorator``. (`#3555
<https://github.com/pytest-dev/pytest/issues/3555>`_)
- Warnings without ``location`` were reported as ``None``. This is corrected to
now report ``<undetermined location>``. (`#3563
<https://github.com/pytest-dev/pytest/issues/3563>`_)
- Continue to call finalizers in the stack when a finalizer in a former scope
raises an exception. (`#3569
<https://github.com/pytest-dev/pytest/issues/3569>`_)
- Fix encoding error with `print` statements in doctests (`#3583
<https://github.com/pytest-dev/pytest/issues/3583>`_)
Improved Documentation
----------------------
- Add documentation for the ``--strict`` flag. (`#3549
<https://github.com/pytest-dev/pytest/issues/3549>`_)
Trivial/Internal Changes
------------------------
- Update old quotation style to parens in fixture.rst documentation. (`#3525
<https://github.com/pytest-dev/pytest/issues/3525>`_)
- Improve display of hint about ``--fulltrace`` with ``KeyboardInterrupt``.
(`#3545 <https://github.com/pytest-dev/pytest/issues/3545>`_)
- pytest's testsuite is no longer runnable through ``python setup.py test`` --
instead invoke ``pytest`` or ``tox`` directly. (`#3552
<https://github.com/pytest-dev/pytest/issues/3552>`_)
- Fix typo in documentation (`#3567
<https://github.com/pytest-dev/pytest/issues/3567>`_)
Pytest 3.6.1 (2018-06-05)
=========================
Bug Fixes
---------
- Fixed a bug where stdout and stderr were logged twice by junitxml when a test
was marked xfail. (`#3491
<https://github.com/pytest-dev/pytest/issues/3491>`_)
- Fix ``usefixtures`` mark applyed to unittest tests by correctly instantiating
``FixtureInfo``. (`#3498
<https://github.com/pytest-dev/pytest/issues/3498>`_)
- Fix assertion rewriter compatibility with libraries that monkey patch
``file`` objects. (`#3503
<https://github.com/pytest-dev/pytest/issues/3503>`_)
Improved Documentation
----------------------
- Added a section on how to use fixtures as factories to the fixture
documentation. (`#3461 <https://github.com/pytest-dev/pytest/issues/3461>`_)
Trivial/Internal Changes
------------------------
- Enable caching for pip/pre-commit in order to reduce build time on
travis/appveyor. (`#3502
<https://github.com/pytest-dev/pytest/issues/3502>`_)
- Switch pytest to the src/ layout as we already suggested it for good practice
- now we implement it as well. (`#3513
<https://github.com/pytest-dev/pytest/issues/3513>`_)
- Fix if in tests to support 3.7.0b5, where a docstring handling in AST got
reverted. (`#3530 <https://github.com/pytest-dev/pytest/issues/3530>`_)
- Remove some python2.5 compatibility code. (`#3529
<https://github.com/pytest-dev/pytest/issues/3529>`_)
Pytest 3.6.0 (2018-05-23)
=========================
Features
--------
- Revamp the internals of the ``pytest.mark`` implementation with correct per
node handling which fixes a number of long standing bugs caused by the old
design. This introduces new ``Node.iter_markers(name)`` and
``Node.get_closest_mark(name)`` APIs. Users are **strongly encouraged** to
read the `reasons for the revamp in the docs
<https://docs.pytest.org/en/latest/mark.html#marker-revamp-and-iteration>`_,
or jump over to details about `updating existing code to use the new APIs
<https://docs.pytest.org/en/latest/mark.html#updating-code>`_. (`#3317
<https://github.com/pytest-dev/pytest/issues/3317>`_)
- Now when ``@pytest.fixture`` is applied more than once to the same function a
``ValueError`` is raised. This buggy behavior would cause surprising problems
and if was working for a test suite it was mostly by accident. (`#2334
<https://github.com/pytest-dev/pytest/issues/2334>`_)
- Support for Python 3.7's builtin ``breakpoint()`` method, see `Using the
builtin breakpoint function
<https://docs.pytest.org/en/latest/usage.html#breakpoint-builtin>`_ for
details. (`#3180 <https://github.com/pytest-dev/pytest/issues/3180>`_)
- ``monkeypatch`` now supports a ``context()`` function which acts as a context
manager which undoes all patching done within the ``with`` block. (`#3290
<https://github.com/pytest-dev/pytest/issues/3290>`_)
- The ``--pdb`` option now causes KeyboardInterrupt to enter the debugger,
instead of stopping the test session. On python 2.7, hitting CTRL+C again
exits the debugger. On python 3.2 and higher, use CTRL+D. (`#3299
<https://github.com/pytest-dev/pytest/issues/3299>`_)
- pytest not longer changes the log level of the root logger when the
``log-level`` parameter has greater numeric value than that of the level of
the root logger, which makes it play better with custom logging configuration
in user code. (`#3307 <https://github.com/pytest-dev/pytest/issues/3307>`_)
Bug Fixes
---------
- A rare race-condition which might result in corrupted ``.pyc`` files on
Windows has been hopefully solved. (`#3008
<https://github.com/pytest-dev/pytest/issues/3008>`_)
- Also use iter_marker for discovering the marks applying for marker
expressions from the cli to avoid the bad data from the legacy mark storage.
(`#3441 <https://github.com/pytest-dev/pytest/issues/3441>`_)
- When showing diffs of failed assertions where the contents contain only
whitespace, escape them using ``repr()`` first to make it easy to spot the
differences. (`#3443 <https://github.com/pytest-dev/pytest/issues/3443>`_)
Improved Documentation
----------------------
- Change documentation copyright year to a range which auto-updates itself each
time it is published. (`#3303
<https://github.com/pytest-dev/pytest/issues/3303>`_)
Trivial/Internal Changes
------------------------
- ``pytest`` now depends on the `python-atomicwrites
<https://github.com/untitaker/python-atomicwrites>`_ library. (`#3008
<https://github.com/pytest-dev/pytest/issues/3008>`_)
- Update all pypi.python.org URLs to pypi.org. (`#3431
<https://github.com/pytest-dev/pytest/issues/3431>`_)
- Detect `pytest_` prefixed hooks using the internal plugin manager since
``pluggy`` is deprecating the ``implprefix`` argument to ``PluginManager``.
(`#3487 <https://github.com/pytest-dev/pytest/issues/3487>`_)
- Import ``Mapping`` and ``Sequence`` from ``_pytest.compat`` instead of
directly from ``collections`` in ``python_api.py::approx``. Add ``Mapping``
to ``_pytest.compat``, import it from ``collections`` on python 2, but from
``collections.abc`` on Python 3 to avoid a ``DeprecationWarning`` on Python
3.7 or newer. (`#3497 <https://github.com/pytest-dev/pytest/issues/3497>`_)
Pytest 3.5.1 (2018-04-23)
=========================
Bug Fixes
---------
- Reset ``sys.last_type``, ``sys.last_value`` and ``sys.last_traceback`` before
each test executes. Those attributes are added by pytest during the test run
to aid debugging, but were never reset so they would create a leaking
reference to the last failing test's frame which in turn could never be
reclaimed by the garbage collector. (`#2798
<https://github.com/pytest-dev/pytest/issues/2798>`_)
- ``pytest.raises`` now raises ``TypeError`` when receiving an unknown keyword
argument. (`#3348 <https://github.com/pytest-dev/pytest/issues/3348>`_)
- ``pytest.raises`` now works with exception classes that look like iterables.
(`#3372 <https://github.com/pytest-dev/pytest/issues/3372>`_)
Improved Documentation
----------------------
- Fix typo in ``caplog`` fixture documentation, which incorrectly identified
certain attributes as methods. (`#3406
<https://github.com/pytest-dev/pytest/issues/3406>`_)
Trivial/Internal Changes
------------------------
- Added a more indicative error message when parametrizing a function whose
argument takes a default value. (`#3221
<https://github.com/pytest-dev/pytest/issues/3221>`_)
- Remove internal ``_pytest.terminal.flatten`` function in favor of
``more_itertools.collapse``. (`#3330
<https://github.com/pytest-dev/pytest/issues/3330>`_)
- Import some modules from ``collections.abc`` instead of ``collections`` as
the former modules trigger ``DeprecationWarning`` in Python 3.7. (`#3339
<https://github.com/pytest-dev/pytest/issues/3339>`_)
- record_property is no longer experimental, removing the warnings was
forgotten. (`#3360 <https://github.com/pytest-dev/pytest/issues/3360>`_)
- Mention in documentation and CLI help that fixtures with leading ``_`` are
printed by ``pytest --fixtures`` only if the ``-v`` option is added. (`#3398
<https://github.com/pytest-dev/pytest/issues/3398>`_)
Pytest 3.5.0 (2018-03-21)
=========================
Deprecations and Removals
-------------------------
- ``record_xml_property`` fixture is now deprecated in favor of the more
generic ``record_property``. (`#2770
<https://github.com/pytest-dev/pytest/issues/2770>`_)
- Defining ``pytest_plugins`` is now deprecated in non-top-level conftest.py
files, because they "leak" to the entire directory tree. (`#3084
<https://github.com/pytest-dev/pytest/issues/3084>`_)
Features
--------
- New ``--show-capture`` command-line option that allows to specify how to
display captured output when tests fail: ``no``, ``stdout``, ``stderr``,
``log`` or ``all`` (the default). (`#1478
<https://github.com/pytest-dev/pytest/issues/1478>`_)
- New ``--rootdir`` command-line option to override the rules for discovering
the root directory. See `customize
<https://docs.pytest.org/en/latest/customize.html>`_ in the documentation for
details. (`#1642 <https://github.com/pytest-dev/pytest/issues/1642>`_)
- Fixtures are now instantiated based on their scopes, with higher-scoped
fixtures (such as ``session``) being instantiated first than lower-scoped
fixtures (such as ``function``). The relative order of fixtures of the same
scope is kept unchanged, based in their declaration order and their
dependencies. (`#2405 <https://github.com/pytest-dev/pytest/issues/2405>`_)
- ``record_xml_property`` renamed to ``record_property`` and is now compatible
with xdist, markers and any reporter. ``record_xml_property`` name is now
deprecated. (`#2770 <https://github.com/pytest-dev/pytest/issues/2770>`_)
- New ``--nf``, ``--new-first`` options: run new tests first followed by the
rest of the tests, in both cases tests are also sorted by the file modified
time, with more recent files coming first. (`#3034
<https://github.com/pytest-dev/pytest/issues/3034>`_)
- New ``--last-failed-no-failures`` command-line option that allows to specify
the behavior of the cache plugin's ```--last-failed`` feature when no tests
failed in the last run (or no cache was found): ``none`` or ``all`` (the
default). (`#3139 <https://github.com/pytest-dev/pytest/issues/3139>`_)
- New ``--doctest-continue-on-failure`` command-line option to enable doctests
to show multiple failures for each snippet, instead of stopping at the first
failure. (`#3149 <https://github.com/pytest-dev/pytest/issues/3149>`_)
- Captured log messages are added to the ``<system-out>`` tag in the generated
junit xml file if the ``junit_logging`` ini option is set to ``system-out``.
If the value of this ini option is ``system-err``, the logs are written to
``<system-err>``. The default value for ``junit_logging`` is ``no``, meaning
captured logs are not written to the output file. (`#3156
<https://github.com/pytest-dev/pytest/issues/3156>`_)
- Allow the logging plugin to handle ``pytest_runtest_logstart`` and
``pytest_runtest_logfinish`` hooks when live logs are enabled. (`#3189
<https://github.com/pytest-dev/pytest/issues/3189>`_)
- Passing `--log-cli-level` in the command-line now automatically activates
live logging. (`#3190 <https://github.com/pytest-dev/pytest/issues/3190>`_)
- Add command line option ``--deselect`` to allow deselection of individual
tests at collection time. (`#3198
<https://github.com/pytest-dev/pytest/issues/3198>`_)
- Captured logs are printed before entering pdb. (`#3204
<https://github.com/pytest-dev/pytest/issues/3204>`_)
- Deselected item count is now shown before tests are run, e.g. ``collected X
items / Y deselected``. (`#3213
<https://github.com/pytest-dev/pytest/issues/3213>`_)
- The builtin module ``platform`` is now available for use in expressions in
``pytest.mark``. (`#3236
<https://github.com/pytest-dev/pytest/issues/3236>`_)
- The *short test summary info* section now is displayed after tracebacks and
warnings in the terminal. (`#3255
<https://github.com/pytest-dev/pytest/issues/3255>`_)
- New ``--verbosity`` flag to set verbosity level explicitly. (`#3296
<https://github.com/pytest-dev/pytest/issues/3296>`_)
- ``pytest.approx`` now accepts comparing a numpy array with a scalar. (`#3312
<https://github.com/pytest-dev/pytest/issues/3312>`_)
Bug Fixes
---------
- Suppress ``IOError`` when closing the temporary file used for capturing
streams in Python 2.7. (`#2370
<https://github.com/pytest-dev/pytest/issues/2370>`_)
- Fixed ``clear()`` method on ``caplog`` fixture which cleared ``records``, but
not the ``text`` property. (`#3297
<https://github.com/pytest-dev/pytest/issues/3297>`_)
- During test collection, when stdin is not allowed to be read, the
``DontReadFromStdin`` object still allow itself to be iterable and resolved
to an iterator without crashing. (`#3314
<https://github.com/pytest-dev/pytest/issues/3314>`_)
Improved Documentation
----------------------
- Added a `reference <https://docs.pytest.org/en/latest/reference.html>`_ page
to the docs. (`#1713 <https://github.com/pytest-dev/pytest/issues/1713>`_)
Trivial/Internal Changes
------------------------
- Change minimum requirement of ``attrs`` to ``17.4.0``. (`#3228
<https://github.com/pytest-dev/pytest/issues/3228>`_)
- Renamed example directories so all tests pass when ran from the base
directory. (`#3245 <https://github.com/pytest-dev/pytest/issues/3245>`_)
- Internal ``mark.py`` module has been turned into a package. (`#3250
<https://github.com/pytest-dev/pytest/issues/3250>`_)
- ``pytest`` now depends on the `more-itertools
<https://github.com/erikrose/more-itertools>`_ package. (`#3265
<https://github.com/pytest-dev/pytest/issues/3265>`_)
- Added warning when ``[pytest]`` section is used in a ``.cfg`` file passed
with ``-c`` (`#3268 <https://github.com/pytest-dev/pytest/issues/3268>`_)
- ``nodeids`` can now be passed explicitly to ``FSCollector`` and ``Node``
constructors. (`#3291 <https://github.com/pytest-dev/pytest/issues/3291>`_)
- Internal refactoring of ``FormattedExcinfo`` to use ``attrs`` facilities and
remove old support code for legacy Python versions. (`#3292
<https://github.com/pytest-dev/pytest/issues/3292>`_)
- Refactoring to unify how verbosity is handled internally. (`#3296
<https://github.com/pytest-dev/pytest/issues/3296>`_)
- Internal refactoring to better integrate with argparse. (`#3304
<https://github.com/pytest-dev/pytest/issues/3304>`_)
- Fix a python example when calling a fixture in doc/en/usage.rst (`#3308
<https://github.com/pytest-dev/pytest/issues/3308>`_)
Pytest 3.4.2 (2018-03-04)
=========================
Bug Fixes
---------
- Removed progress information when capture option is ``no``. (`#3203
<https://github.com/pytest-dev/pytest/issues/3203>`_)
- Refactor check of bindir from ``exists`` to ``isdir``. (`#3241
<https://github.com/pytest-dev/pytest/issues/3241>`_)
- Fix ``TypeError`` issue when using ``approx`` with a ``Decimal`` value.
(`#3247 <https://github.com/pytest-dev/pytest/issues/3247>`_)
- Fix reference cycle generated when using the ``request`` fixture. (`#3249
<https://github.com/pytest-dev/pytest/issues/3249>`_)
- ``[tool:pytest]`` sections in ``*.cfg`` files passed by the ``-c`` option are
now properly recognized. (`#3260
<https://github.com/pytest-dev/pytest/issues/3260>`_)
Improved Documentation
----------------------
- Add logging plugin to plugins list. (`#3209
<https://github.com/pytest-dev/pytest/issues/3209>`_)
Trivial/Internal Changes
------------------------
- Fix minor typo in fixture.rst (`#3259
<https://github.com/pytest-dev/pytest/issues/3259>`_)
Pytest 3.4.1 (2018-02-20)
=========================
Bug Fixes
---------
- Move import of ``doctest.UnexpectedException`` to top-level to avoid possible
errors when using ``--pdb``. (`#1810
<https://github.com/pytest-dev/pytest/issues/1810>`_)
- Added printing of captured stdout/stderr before entering pdb, and improved a
test which was giving false negatives about output capturing. (`#3052
<https://github.com/pytest-dev/pytest/issues/3052>`_)
- Fix ordering of tests using parametrized fixtures which can lead to fixtures
being created more than necessary. (`#3161
<https://github.com/pytest-dev/pytest/issues/3161>`_)
- Fix bug where logging happening at hooks outside of "test run" hooks would
cause an internal error. (`#3184
<https://github.com/pytest-dev/pytest/issues/3184>`_)
- Detect arguments injected by ``unittest.mock.patch`` decorator correctly when
pypi ``mock.patch`` is installed and imported. (`#3206
<https://github.com/pytest-dev/pytest/issues/3206>`_)
- Errors shown when a ``pytest.raises()`` with ``match=`` fails are now cleaner
on what happened: When no exception was raised, the "matching '...'" part got
removed as it falsely implies that an exception was raised but it didn't
match. When a wrong exception was raised, it's now thrown (like
``pytest.raised()`` without ``match=`` would) instead of complaining about
the unmatched text. (`#3222
<https://github.com/pytest-dev/pytest/issues/3222>`_)
- Fixed output capture handling in doctests on macOS. (`#985
<https://github.com/pytest-dev/pytest/issues/985>`_)
Improved Documentation
----------------------
- Add Sphinx parameter docs for ``match`` and ``message`` args to
``pytest.raises``. (`#3202
<https://github.com/pytest-dev/pytest/issues/3202>`_)
Trivial/Internal Changes
------------------------
- pytest has changed the publication procedure and is now being published to
PyPI directly from Travis. (`#3060
<https://github.com/pytest-dev/pytest/issues/3060>`_)
- Rename ``ParameterSet._for_parameterize()`` to ``_for_parametrize()`` in
order to comply with the naming convention. (`#3166
<https://github.com/pytest-dev/pytest/issues/3166>`_)
- Skip failing pdb/doctest test on mac. (`#985
<https://github.com/pytest-dev/pytest/issues/985>`_)
Pytest 3.4.0 (2018-01-30)
=========================
Deprecations and Removals
-------------------------
- All pytest classes now subclass ``object`` for better Python 2/3 compatibility.
This should not affect user code except in very rare edge cases. (`#2147
<https://github.com/pytest-dev/pytest/issues/2147>`_)
Features
--------
- Introduce ``empty_parameter_set_mark`` ini option to select which mark to
apply when ``@pytest.mark.parametrize`` is given an empty set of parameters.
Valid options are ``skip`` (default) and ``xfail``. Note that it is planned
to change the default to ``xfail`` in future releases as this is considered
less error prone. (`#2527
<https://github.com/pytest-dev/pytest/issues/2527>`_)
- **Incompatible change**: after community feedback the `logging
<https://docs.pytest.org/en/latest/logging.html>`_ functionality has
undergone some changes. Please consult the `logging documentation
<https://docs.pytest.org/en/latest/logging.html#incompatible-changes-in-pytest-3-4>`_
for details. (`#3013 <https://github.com/pytest-dev/pytest/issues/3013>`_)
- Console output falls back to "classic" mode when capturing is disabled (``-s``),
otherwise the output gets garbled to the point of being useless. (`#3038
<https://github.com/pytest-dev/pytest/issues/3038>`_)
- New `pytest_runtest_logfinish
<https://docs.pytest.org/en/latest/writing_plugins.html#_pytest.hookspec.pytest_runtest_logfinish>`_
hook which is called when a test item has finished executing, analogous to
`pytest_runtest_logstart
<https://docs.pytest.org/en/latest/writing_plugins.html#_pytest.hookspec.pytest_runtest_start>`_.
(`#3101 <https://github.com/pytest-dev/pytest/issues/3101>`_)
- Improve performance when collecting tests using many fixtures. (`#3107
<https://github.com/pytest-dev/pytest/issues/3107>`_)
- New ``caplog.get_records(when)`` method which provides access to the captured
records for the ``"setup"``, ``"call"`` and ``"teardown"``
testing stages. (`#3117 <https://github.com/pytest-dev/pytest/issues/3117>`_)
- New fixture ``record_xml_attribute`` that allows modifying and inserting
attributes on the ``<testcase>`` xml node in JUnit reports. (`#3130
<https://github.com/pytest-dev/pytest/issues/3130>`_)
- The default cache directory has been renamed from ``.cache`` to
``.pytest_cache`` after community feedback that the name ``.cache`` did not
make it clear that it was used by pytest. (`#3138
<https://github.com/pytest-dev/pytest/issues/3138>`_)
- Colorize the levelname column in the live-log output. (`#3142
<https://github.com/pytest-dev/pytest/issues/3142>`_)
Bug Fixes
---------
- Fix hanging pexpect test on MacOS by using flush() instead of wait().
(`#2022 <https://github.com/pytest-dev/pytest/issues/2022>`_)
- Fix restoring Python state after in-process pytest runs with the
``pytester`` plugin; this may break tests using multiple inprocess
pytest runs if later ones depend on earlier ones leaking global interpreter
changes. (`#3016 <https://github.com/pytest-dev/pytest/issues/3016>`_)
- Fix skipping plugin reporting hook when test aborted before plugin setup
hook. (`#3074 <https://github.com/pytest-dev/pytest/issues/3074>`_)
- Fix progress percentage reported when tests fail during teardown. (`#3088
<https://github.com/pytest-dev/pytest/issues/3088>`_)
- **Incompatible change**: ``-o/--override`` option no longer eats all the
remaining options, which can lead to surprising behavior: for example,
``pytest -o foo=1 /path/to/test.py`` would fail because ``/path/to/test.py``
would be considered as part of the ``-o`` command-line argument. One
consequence of this is that now multiple configuration overrides need
multiple ``-o`` flags: ``pytest -o foo=1 -o bar=2``. (`#3103
<https://github.com/pytest-dev/pytest/issues/3103>`_)
Improved Documentation
----------------------
- Document hooks (defined with ``historic=True``) which cannot be used with
``hookwrapper=True``. (`#2423
<https://github.com/pytest-dev/pytest/issues/2423>`_)
- Clarify that warning capturing doesn't change the warning filter by default.
(`#2457 <https://github.com/pytest-dev/pytest/issues/2457>`_)
- Clarify a possible confusion when using pytest_fixture_setup with fixture
functions that return None. (`#2698
<https://github.com/pytest-dev/pytest/issues/2698>`_)
- Fix the wording of a sentence on doctest flags used in pytest. (`#3076
<https://github.com/pytest-dev/pytest/issues/3076>`_)
- Prefer ``https://*.readthedocs.io`` over ``http://*.rtfd.org`` for links in
the documentation. (`#3092
<https://github.com/pytest-dev/pytest/issues/3092>`_)
- Improve readability (wording, grammar) of Getting Started guide (`#3131
<https://github.com/pytest-dev/pytest/issues/3131>`_)
- Added note that calling pytest.main multiple times from the same process is
not recommended because of import caching. (`#3143
<https://github.com/pytest-dev/pytest/issues/3143>`_)
Trivial/Internal Changes
------------------------
- Show a simple and easy error when keyword expressions trigger a syntax error
(for example, ``"-k foo and import"`` will show an error that you can not use
the ``import`` keyword in expressions). (`#2953
<https://github.com/pytest-dev/pytest/issues/2953>`_)
- Change parametrized automatic test id generation to use the ``__name__``
attribute of functions instead of the fallback argument name plus counter.
(`#2976 <https://github.com/pytest-dev/pytest/issues/2976>`_)
- Replace py.std with stdlib imports. (`#3067
<https://github.com/pytest-dev/pytest/issues/3067>`_)
- Corrected 'you' to 'your' in logging docs. (`#3129
<https://github.com/pytest-dev/pytest/issues/3129>`_)
Pytest 3.3.2 (2017-12-25)
=========================
Bug Fixes
---------
- pytester: ignore files used to obtain current user metadata in the fd leak
detector. (`#2784 <https://github.com/pytest-dev/pytest/issues/2784>`_)
- Fix **memory leak** where objects returned by fixtures were never destructed
by the garbage collector. (`#2981
<https://github.com/pytest-dev/pytest/issues/2981>`_)
- Fix conversion of pyargs to filename to not convert symlinks on Python 2. (`#2985
<https://github.com/pytest-dev/pytest/issues/2985>`_)
- ``PYTEST_DONT_REWRITE`` is now checked for plugins too rather than only for
test modules. (`#2995 <https://github.com/pytest-dev/pytest/issues/2995>`_)
Improved Documentation
----------------------
- Add clarifying note about behavior of multiple parametrized arguments (`#3001
<https://github.com/pytest-dev/pytest/issues/3001>`_)
Trivial/Internal Changes
------------------------
- Code cleanup. (`#3015 <https://github.com/pytest-dev/pytest/issues/3015>`_,
`#3021 <https://github.com/pytest-dev/pytest/issues/3021>`_)
- Clean up code by replacing imports and references of `_ast` to `ast`. (`#3018
<https://github.com/pytest-dev/pytest/issues/3018>`_)
Pytest 3.3.1 (2017-12-05)
=========================
Bug Fixes
---------
- Fix issue about ``-p no:<plugin>`` having no effect. (`#2920
<https://github.com/pytest-dev/pytest/issues/2920>`_)
- Fix regression with warnings that contained non-strings in their arguments in
Python 2. (`#2956 <https://github.com/pytest-dev/pytest/issues/2956>`_)
- Always escape null bytes when setting ``PYTEST_CURRENT_TEST``. (`#2957
<https://github.com/pytest-dev/pytest/issues/2957>`_)
- Fix ``ZeroDivisionError`` when using the ``testmon`` plugin when no tests
were actually collected. (`#2971
<https://github.com/pytest-dev/pytest/issues/2971>`_)
- Bring back ``TerminalReporter.writer`` as an alias to
``TerminalReporter._tw``. This alias was removed by accident in the ``3.3.0``
release. (`#2984 <https://github.com/pytest-dev/pytest/issues/2984>`_)
- The ``pytest-capturelog`` plugin is now also blacklisted, avoiding errors when
running pytest with it still installed. (`#3004
<https://github.com/pytest-dev/pytest/issues/3004>`_)
Improved Documentation
----------------------
- Fix broken link to plugin ``pytest-localserver``. (`#2963
<https://github.com/pytest-dev/pytest/issues/2963>`_)
Trivial/Internal Changes
------------------------
- Update github "bugs" link in ``CONTRIBUTING.rst`` (`#2949
<https://github.com/pytest-dev/pytest/issues/2949>`_)
Pytest 3.3.0 (2017-11-23)
=========================
Deprecations and Removals
-------------------------
- Pytest no longer supports Python **2.6** and **3.3**. Those Python versions
are EOL for some time now and incur maintenance and compatibility costs on
the pytest core team, and following up with the rest of the community we
decided that they will no longer be supported starting on this version. Users
which still require those versions should pin pytest to ``<3.3``. (`#2812
<https://github.com/pytest-dev/pytest/issues/2812>`_)
- Remove internal ``_preloadplugins()`` function. This removal is part of the
``pytest_namespace()`` hook deprecation. (`#2636
<https://github.com/pytest-dev/pytest/issues/2636>`_)
- Internally change ``CallSpec2`` to have a list of marks instead of a broken
mapping of keywords. This removes the keywords attribute of the internal
``CallSpec2`` class. (`#2672
<https://github.com/pytest-dev/pytest/issues/2672>`_)
- Remove ParameterSet.deprecated_arg_dict - its not a public api and the lack
of the underscore was a naming error. (`#2675
<https://github.com/pytest-dev/pytest/issues/2675>`_)
- Remove the internal multi-typed attribute ``Node._evalskip`` and replace it
with the boolean ``Node._skipped_by_mark``. (`#2767
<https://github.com/pytest-dev/pytest/issues/2767>`_)
- The ``params`` list passed to ``pytest.fixture`` is now for
all effects considered immutable and frozen at the moment of the ``pytest.fixture``
call. Previously the list could be changed before the first invocation of the fixture
allowing for a form of dynamic parametrization (for example, updated from command-line options),
but this was an unwanted implementation detail which complicated the internals and prevented
some internal cleanup. See issue `#2959 <https://github.com/pytest-dev/pytest/issues/2959>`_
for details and a recommended workaround.
Features
--------
- ``pytest_fixture_post_finalizer`` hook can now receive a ``request``
argument. (`#2124 <https://github.com/pytest-dev/pytest/issues/2124>`_)
- Replace the old introspection code in compat.py that determines the available
arguments of fixtures with inspect.signature on Python 3 and
funcsigs.signature on Python 2. This should respect ``__signature__``
declarations on functions. (`#2267
<https://github.com/pytest-dev/pytest/issues/2267>`_)
- Report tests with global ``pytestmark`` variable only once. (`#2549
<https://github.com/pytest-dev/pytest/issues/2549>`_)
- Now pytest displays the total progress percentage while running tests. The
previous output style can be set by configuring the ``console_output_style``
setting to ``classic``. (`#2657 <https://github.com/pytest-dev/pytest/issues/2657>`_)
- Match ``warns`` signature to ``raises`` by adding ``match`` keyword. (`#2708
<https://github.com/pytest-dev/pytest/issues/2708>`_)
- Pytest now captures and displays output from the standard ``logging`` module.
The user can control the logging level to be captured by specifying options
in ``pytest.ini``, the command line and also during individual tests using
markers. Also, a ``caplog`` fixture is available that enables users to test
the captured log during specific tests (similar to ``capsys`` for example).
For more information, please see the `logging docs
<https://docs.pytest.org/en/latest/logging.html>`_. This feature was
introduced by merging the popular `pytest-catchlog
<https://pypi.org/project/pytest-catchlog/>`_ plugin, thanks to `Thomas Hisch
<https://github.com/thisch>`_. Be advised that during the merging the
backward compatibility interface with the defunct ``pytest-capturelog`` has
been dropped. (`#2794 <https://github.com/pytest-dev/pytest/issues/2794>`_)
- Add ``allow_module_level`` kwarg to ``pytest.skip()``, enabling to skip the
whole module. (`#2808 <https://github.com/pytest-dev/pytest/issues/2808>`_)
- Allow setting ``file_or_dir``, ``-c``, and ``-o`` in PYTEST_ADDOPTS. (`#2824
<https://github.com/pytest-dev/pytest/issues/2824>`_)
- Return stdout/stderr capture results as a ``namedtuple``, so ``out`` and
``err`` can be accessed by attribute. (`#2879
<https://github.com/pytest-dev/pytest/issues/2879>`_)
- Add ``capfdbinary``, a version of ``capfd`` which returns bytes from
``readouterr()``. (`#2923
<https://github.com/pytest-dev/pytest/issues/2923>`_)
- Add ``capsysbinary`` a version of ``capsys`` which returns bytes from
``readouterr()``. (`#2934
<https://github.com/pytest-dev/pytest/issues/2934>`_)
- Implement feature to skip ``setup.py`` files when run with
``--doctest-modules``. (`#502
<https://github.com/pytest-dev/pytest/issues/502>`_)
Bug Fixes
---------
- Resume output capturing after ``capsys/capfd.disabled()`` context manager.
(`#1993 <https://github.com/pytest-dev/pytest/issues/1993>`_)
- ``pytest_fixture_setup`` and ``pytest_fixture_post_finalizer`` hooks are now
called for all ``conftest.py`` files. (`#2124
<https://github.com/pytest-dev/pytest/issues/2124>`_)
- If an exception happens while loading a plugin, pytest no longer hides the
original traceback. In Python 2 it will show the original traceback with a new
message that explains in which plugin. In Python 3 it will show 2 canonized
exceptions, the original exception while loading the plugin in addition to an
exception that pytest throws about loading a plugin. (`#2491
<https://github.com/pytest-dev/pytest/issues/2491>`_)
- ``capsys`` and ``capfd`` can now be used by other fixtures. (`#2709
<https://github.com/pytest-dev/pytest/issues/2709>`_)
- Internal ``pytester`` plugin properly encodes ``bytes`` arguments to
``utf-8``. (`#2738 <https://github.com/pytest-dev/pytest/issues/2738>`_)
- ``testdir`` now uses use the same method used by ``tmpdir`` to create its
temporary directory. This changes the final structure of the ``testdir``
directory slightly, but should not affect usage in normal scenarios and
avoids a number of potential problems. (`#2751
<https://github.com/pytest-dev/pytest/issues/2751>`_)
- Pytest no longer complains about warnings with unicode messages being
non-ascii compatible even for ascii-compatible messages. As a result of this,
warnings with unicode messages are converted first to an ascii representation
for safety. (`#2809 <https://github.com/pytest-dev/pytest/issues/2809>`_)
- Change return value of pytest command when ``--maxfail`` is reached from
``2`` (interrupted) to ``1`` (failed). (`#2845
<https://github.com/pytest-dev/pytest/issues/2845>`_)
- Fix issue in assertion rewriting which could lead it to rewrite modules which
should not be rewritten. (`#2939
<https://github.com/pytest-dev/pytest/issues/2939>`_)
- Handle marks without description in ``pytest.ini``. (`#2942
<https://github.com/pytest-dev/pytest/issues/2942>`_)
Trivial/Internal Changes
------------------------
- pytest now depends on `attrs <https://pypi.org/project/attrs/>`_ for internal
structures to ease code maintainability. (`#2641
<https://github.com/pytest-dev/pytest/issues/2641>`_)
- Refactored internal Python 2/3 compatibility code to use ``six``. (`#2642
<https://github.com/pytest-dev/pytest/issues/2642>`_)
- Stop vendoring ``pluggy`` - we're missing out on its latest changes for not
much benefit (`#2719 <https://github.com/pytest-dev/pytest/issues/2719>`_)
- Internal refactor: simplify ascii string escaping by using the
backslashreplace error handler in newer Python 3 versions. (`#2734
<https://github.com/pytest-dev/pytest/issues/2734>`_)
- Remove unnecessary mark evaluator in unittest plugin (`#2767
<https://github.com/pytest-dev/pytest/issues/2767>`_)
- Calls to ``Metafunc.addcall`` now emit a deprecation warning. This function
is scheduled to be removed in ``pytest-4.0``. (`#2876
<https://github.com/pytest-dev/pytest/issues/2876>`_)
- Internal move of the parameterset extraction to a more maintainable place.
(`#2877 <https://github.com/pytest-dev/pytest/issues/2877>`_)
- Internal refactoring to simplify scope node lookup. (`#2910
<https://github.com/pytest-dev/pytest/issues/2910>`_)
- Configure ``pytest`` to prevent pip from installing pytest in unsupported
Python versions. (`#2922
<https://github.com/pytest-dev/pytest/issues/2922>`_)
Pytest 3.2.5 (2017-11-15)
=========================
Bug Fixes
---------
- Remove ``py<1.5`` restriction from ``pytest`` as this can cause version
conflicts in some installations. (`#2926
<https://github.com/pytest-dev/pytest/issues/2926>`_)
Pytest 3.2.4 (2017-11-13)
=========================
Bug Fixes
---------
- Fix the bug where running with ``--pyargs`` will result in items with
empty ``parent.nodeid`` if run from a different root directory. (`#2775
<https://github.com/pytest-dev/pytest/issues/2775>`_)
- Fix issue with ``@pytest.parametrize`` if argnames was specified as keyword arguments.
(`#2819 <https://github.com/pytest-dev/pytest/issues/2819>`_)
- Strip whitespace from marker names when reading them from INI config. (`#2856
<https://github.com/pytest-dev/pytest/issues/2856>`_)
- Show full context of doctest source in the pytest output, if the line number of
failed example in the docstring is < 9. (`#2882
<https://github.com/pytest-dev/pytest/issues/2882>`_)
- Match fixture paths against actual path segments in order to avoid matching folders which share a prefix.
(`#2836 <https://github.com/pytest-dev/pytest/issues/2836>`_)
Improved Documentation
----------------------
- Introduce a dedicated section about conftest.py. (`#1505
<https://github.com/pytest-dev/pytest/issues/1505>`_)
- Explicitly mention ``xpass`` in the documentation of ``xfail``. (`#1997
<https://github.com/pytest-dev/pytest/issues/1997>`_)
- Append example for pytest.param in the example/parametrize document. (`#2658
<https://github.com/pytest-dev/pytest/issues/2658>`_)
- Clarify language of proposal for fixtures parameters (`#2893
<https://github.com/pytest-dev/pytest/issues/2893>`_)
- List python 3.6 in the documented supported versions in the getting started
document. (`#2903 <https://github.com/pytest-dev/pytest/issues/2903>`_)
- Clarify the documentation of available fixture scopes. (`#538
<https://github.com/pytest-dev/pytest/issues/538>`_)
- Add documentation about the ``python -m pytest`` invocation adding the
current directory to sys.path. (`#911
<https://github.com/pytest-dev/pytest/issues/911>`_)
Pytest 3.2.3 (2017-10-03)
=========================
Bug Fixes
---------
- Fix crash in tab completion when no prefix is given. (`#2748
<https://github.com/pytest-dev/pytest/issues/2748>`_)
- The equality checking function (``__eq__``) of ``MarkDecorator`` returns
``False`` if one object is not an instance of ``MarkDecorator``. (`#2758
<https://github.com/pytest-dev/pytest/issues/2758>`_)
- When running ``pytest --fixtures-per-test``: don't crash if an item has no
_fixtureinfo attribute (e.g. doctests) (`#2788
<https://github.com/pytest-dev/pytest/issues/2788>`_)
Improved Documentation
----------------------
- In help text of ``-k`` option, add example of using ``not`` to not select
certain tests whose names match the provided expression. (`#1442
<https://github.com/pytest-dev/pytest/issues/1442>`_)
- Add note in ``parametrize.rst`` about calling ``metafunc.parametrize``
multiple times. (`#1548 <https://github.com/pytest-dev/pytest/issues/1548>`_)
Trivial/Internal Changes
------------------------
- Set ``xfail_strict=True`` in pytest's own test suite to catch expected
failures as soon as they start to pass. (`#2722
<https://github.com/pytest-dev/pytest/issues/2722>`_)
- Fix typo in example of passing a callable to markers (in example/markers.rst)
(`#2765 <https://github.com/pytest-dev/pytest/issues/2765>`_)
Pytest 3.2.2 (2017-09-06)
=========================
Bug Fixes
---------
- Calling the deprecated `request.getfuncargvalue()` now shows the source of
the call. (`#2681 <https://github.com/pytest-dev/pytest/issues/2681>`_)
- Allow tests declared as ``@staticmethod`` to use fixtures. (`#2699
<https://github.com/pytest-dev/pytest/issues/2699>`_)
- Fixed edge-case during collection: attributes which raised ``pytest.fail``
when accessed would abort the entire collection. (`#2707
<https://github.com/pytest-dev/pytest/issues/2707>`_)
- Fix ``ReprFuncArgs`` with mixed unicode and UTF-8 args. (`#2731
<https://github.com/pytest-dev/pytest/issues/2731>`_)
Improved Documentation

usage of ``pytest.mark.MARKER_NAME.with_args`` in comparison with
``pytest.mark.MARKER_NAME.__call__`` (`#2604
<https://github.com/pytest-dev/pytest/issues/2604>`_)
- In one of the simple examples, use `pytest_collection_modifyitems()` to skip
tests based on a command-line option, allowing its sharing while preventing a
user error when acessing `pytest.config` before the argument parsing. (`#2653
<https://github.com/pytest-dev/pytest/issues/2653>`_)
Trivial/Internal Changes
------------------------
- Fixed minor error in 'Good Practices/Manual Integration' code snippet.
(`#2691 <https://github.com/pytest-dev/pytest/issues/2691>`_)
- Fixed typo in goodpractices.rst. (`#2721
<https://github.com/pytest-dev/pytest/issues/2721>`_)
- Improve user guidance regarding ``--resultlog`` deprecation. (`#2739
<https://github.com/pytest-dev/pytest/issues/2739>`_)
Pytest 3.2.1 (2017-08-08)
=========================
Bug Fixes
---------
- Fixed small terminal glitch when collecting a single test item. (`#2579
<https://github.com/pytest-dev/pytest/issues/2579>`_)
- Correctly consider ``/`` as the file separator to automatically mark plugin
files for rewrite on Windows. (`#2591 <https://github.com/pytest-
dev/pytest/issues/2591>`_)
- Properly escape test names when setting ``PYTEST_CURRENT_TEST`` environment
variable. (`#2644 <https://github.com/pytest-dev/pytest/issues/2644>`_)
- Fix error on Windows and Python 3.6+ when ``sys.stdout`` has been replaced
with a stream-like object which does not implement the full ``io`` module
buffer protocol. In particular this affects ``pytest-xdist`` users on the
aforementioned platform. (`#2666 <https://github.com/pytest-
dev/pytest/issues/2666>`_)
Improved Documentation
----------------------
- Explicitly document which pytest features work with ``unittest``. (`#2626
<https://github.com/pytest-dev/pytest/issues/2626>`_)
Pytest 3.2.0 (2017-07-30)
=========================
Deprecations and Removals
-------------------------
- ``pytest.approx`` no longer supports ``>``, ``>=``, ``<`` and ``<=``
operators to avoid surprising/inconsistent behavior. See `the approx docs
<https://docs.pytest.org/en/latest/builtin.html#pytest.approx>`_ for more
information. (`#2003 <https://github.com/pytest-dev/pytest/issues/2003>`_)
- All old-style specific behavior in current classes in the pytest's API is
considered deprecated at this point and will be removed in a future release.
This affects Python 2 users only and in rare situations. (`#2147
<https://github.com/pytest-dev/pytest/issues/2147>`_)
- A deprecation warning is now raised when using marks for parameters
in ``pytest.mark.parametrize``. Use ``pytest.param`` to apply marks to
parameters instead. (`#2427 <https://github.com/pytest-dev/pytest/issues/2427>`_)
Features
--------
- Add support for numpy arrays (and dicts) to approx. (`#1994
<https://github.com/pytest-dev/pytest/issues/1994>`_)
- Now test function objects have a ``pytestmark`` attribute containing a list
of marks applied directly to the test function, as opposed to marks inherited
from parent classes or modules. (`#2516 <https://github.com/pytest-
dev/pytest/issues/2516>`_)
- Collection ignores local virtualenvs by default; `--collect-in-virtualenv`
overrides this behavior. (`#2518 <https://github.com/pytest-
dev/pytest/issues/2518>`_)
- Allow class methods decorated as ``@staticmethod`` to be candidates for
collection as a test function. (Only for Python 2.7 and above. Python 2.6
will still ignore static methods.) (`#2528 <https://github.com/pytest-
dev/pytest/issues/2528>`_)
- Introduce ``mark.with_args`` in order to allow passing functions/classes as
sole argument to marks. (`#2540 <https://github.com/pytest-
dev/pytest/issues/2540>`_)
- New ``cache_dir`` ini option: sets the directory where the contents of the
cache plugin are stored. Directory may be relative or absolute path: if relative path, then
directory is created relative to ``rootdir``, otherwise it is used as is.
Additionally path may contain environment variables which are expanded during
runtime. (`#2543 <https://github.com/pytest-dev/pytest/issues/2543>`_)
- Introduce the ``PYTEST_CURRENT_TEST`` environment variable that is set with
the ``nodeid`` and stage (``setup``, ``call`` and ``teardown``) of the test
being currently executed. See the `documentation
<https://docs.pytest.org/en/latest/example/simple.html#pytest-current-test-
environment-variable>`_ for more info. (`#2583 <https://github.com/pytest-
dev/pytest/issues/2583>`_)
- Introduced ``@pytest.mark.filterwarnings`` mark which allows overwriting the
warnings filter on a per test, class or module level. See the `docs
<https://docs.pytest.org/en/latest/warnings.html#pytest-mark-
filterwarnings>`_ for more information. (`#2598 <https://github.com/pytest-
dev/pytest/issues/2598>`_)
- ``--last-failed`` now remembers forever when a test has failed and only
forgets it if it passes again. This makes it easy to fix a test suite by
selectively running files and fixing tests incrementally. (`#2621
<https://github.com/pytest-dev/pytest/issues/2621>`_)
- New ``pytest_report_collectionfinish`` hook which allows plugins to add
messages to the terminal reporting after collection has been finished
successfully. (`#2622 <https://github.com/pytest-dev/pytest/issues/2622>`_)
- Added support for `PEP-415's <https://www.python.org/dev/peps/pep-0415/>`_
``Exception.__suppress_context__``. Now if a ``raise exception from None`` is
caught by pytest, pytest will no longer chain the context in the test report.
The behavior now matches Python's traceback behavior. (`#2631
<https://github.com/pytest-dev/pytest/issues/2631>`_)
- Exceptions raised by ``pytest.fail``, ``pytest.skip`` and ``pytest.xfail``
now subclass BaseException, making them harder to be caught unintentionally
by normal code. (`#580 <https://github.com/pytest-dev/pytest/issues/580>`_)
Bug Fixes
---------
- Set ``stdin`` to a closed ``PIPE`` in ``pytester.py.Testdir.popen()`` for
avoid unwanted interactive ``pdb`` (`#2023 <https://github.com/pytest-
dev/pytest/issues/2023>`_)
- Add missing ``encoding`` attribute to ``sys.std*`` streams when using
``capsys`` capture mode. (`#2375 <https://github.com/pytest-
dev/pytest/issues/2375>`_)
- Fix terminal color changing to black on Windows if ``colorama`` is imported
in a ``conftest.py`` file. (`#2510 <https://github.com/pytest-
dev/pytest/issues/2510>`_)
- Fix line number when reporting summary of skipped tests. (`#2548
<https://github.com/pytest-dev/pytest/issues/2548>`_)
- capture: ensure that EncodedFile.name is a string. (`#2555
<https://github.com/pytest-dev/pytest/issues/2555>`_)
- The options ``--fixtures`` and ``--fixtures-per-test`` will now keep
indentation within docstrings. (`#2574 <https://github.com/pytest-
dev/pytest/issues/2574>`_)
- doctests line numbers are now reported correctly, fixing `pytest-sugar#122
<https://github.com/Frozenball/pytest-sugar/issues/122>`_. (`#2610
<https://github.com/pytest-dev/pytest/issues/2610>`_)
- Fix non-determinism in order of fixture collection. Adds new dependency
(ordereddict) for Python 2.6. (`#920 <https://github.com/pytest-
dev/pytest/issues/920>`_)
Improved Documentation
----------------------
- Clarify ``pytest_configure`` hook call order. (`#2539
<https://github.com/pytest-dev/pytest/issues/2539>`_)
- Extend documentation for testing plugin code with the ``pytester`` plugin.
(`#971 <https://github.com/pytest-dev/pytest/issues/971>`_)
Trivial/Internal Changes
------------------------
- Update help message for ``--strict`` to make it clear it only deals with
unregistered markers, not warnings. (`#2444 <https://github.com/pytest-
dev/pytest/issues/2444>`_)
- Internal code move: move code for pytest.approx/pytest.raises to own files in
order to cut down the size of python.py (`#2489 <https://github.com/pytest-
dev/pytest/issues/2489>`_)
- Renamed the utility function ``_pytest.compat._escape_strings`` to
``_ascii_escaped`` to better communicate the function's purpose. (`#2533
<https://github.com/pytest-dev/pytest/issues/2533>`_)
- Improve error message for CollectError with skip/skipif. (`#2546
<https://github.com/pytest-dev/pytest/issues/2546>`_)
- Emit warning about ``yield`` tests being deprecated only once per generator.
(`#2562 <https://github.com/pytest-dev/pytest/issues/2562>`_)
- Ensure final collected line doesn't include artifacts of previous write.
(`#2571 <https://github.com/pytest-dev/pytest/issues/2571>`_)
- Fixed all flake8 errors and warnings. (`#2581 <https://github.com/pytest-
dev/pytest/issues/2581>`_)
- Added ``fix-lint`` tox environment to run automatic pep8 fixes on the code.
(`#2582 <https://github.com/pytest-dev/pytest/issues/2582>`_)
- Turn warnings into errors in pytest's own test suite in order to catch
regressions due to deprecations more promptly. (`#2588
<https://github.com/pytest-dev/pytest/issues/2588>`_)
- Show multiple issue links in CHANGELOG entries. (`#2620
<https://github.com/pytest-dev/pytest/issues/2620>`_)
Pytest 3.1.3 (2017-07-03)
=========================
Bug Fixes
---------
- Fix decode error in Python 2 for doctests in docstrings. (`#2434
<https://github.com/pytest-dev/pytest/issues/2434>`_)
- Exceptions raised during teardown by finalizers are now suppressed until all
finalizers are called, with the initial exception reraised. (`#2440
<https://github.com/pytest-dev/pytest/issues/2440>`_)
- Fix incorrect "collected items" report when specifying tests on the command-
line. (`#2464 <https://github.com/pytest-dev/pytest/issues/2464>`_)
- ``deprecated_call`` in context-manager form now captures deprecation warnings
even if the same warning has already been raised. Also, ``deprecated_call``
will always produce the same error message (previously it would produce
different messages in context-manager vs. function-call mode). (`#2469
<https://github.com/pytest-dev/pytest/issues/2469>`_)
- Fix issue where paths collected by pytest could have triple leading ``/``
characters. (`#2475 <https://github.com/pytest-dev/pytest/issues/2475>`_)

------------------------
- Create invoke tasks for updating the vendored packages. (`#2474
<https://github.com/pytest-dev/pytest/issues/2474>`_)
- Update copyright dates in LICENSE, README.rst and in the documentation.
(`#2499 <https://github.com/pytest-dev/pytest/issues/2499>`_)
Pytest 3.1.2 (2017-06-08)
=========================
Bug Fixes
---------
- Required options added via ``pytest_addoption`` will no longer prevent using
--help without passing them. (#1999)
- Respect ``python_files`` in assertion rewriting. (#2121)
- Fix recursion error detection when frames in the traceback contain objects
that can't be compared (like ``numpy`` arrays). (#2459)
- ``UnicodeWarning`` is issued from the internal pytest warnings plugin only
when the message contains non-ascii unicode (Python 2 only). (#2463)
- Added a workaround for Python 3.6 ``WindowsConsoleIO`` breaking due to Pytests's
``FDCapture``. Other code using console handles might still be affected by the
very same issue and might require further workarounds/fixes, i.e. ``colorama``.
(#2467)
Improved Documentation
----------------------
- Fix internal API links to ``pluggy`` objects. (#2331)
- Make it clear that ``pytest.xfail`` stops test execution at the calling point
and improve overall flow of the ``skipping`` docs. (#810)
Pytest 3.1.1 (2017-05-30)
=========================
Bug Fixes
---------
- pytest warning capture no longer overrides existing warning filters. The
previous behaviour would override all filters and caused regressions in test
suites which configure warning filters to match their needs. Note that as a
side-effect of this is that ``DeprecationWarning`` and
``PendingDeprecationWarning`` are no longer shown by default. (#2430)
- Fix issue with non-ascii contents in doctest text files. (#2434)
- Fix encoding errors for unicode warnings in Python 2. (#2436)
- ``pytest.deprecated_call`` now captures ``PendingDeprecationWarning`` in
context manager form. (#2441)
Improved Documentation
----------------------
- Addition of towncrier for changelog management. (#2390)
3.1.0 (2017-05-22)
==================
New Features
------------
* The ``pytest-warnings`` plugin has been integrated into the core and now ``pytest`` automatically
captures and displays warnings at the end of the test session.
.. warning::
This feature may disrupt test suites which apply and treat warnings themselves, and can be
disabled in your ``pytest.ini``:
.. code-block:: ini
[pytest]
addopts = -p no:warnings
See the `warnings documentation page <https://docs.pytest.org/en/latest/warnings.html>`_ for more
information.
Thanks `@nicoddemus`_ for the PR.
* Added ``junit_suite_name`` ini option to specify root ``<testsuite>`` name for JUnit XML reports (`#533`_).
* Added an ini option ``doctest_encoding`` to specify which encoding to use for doctest files.
Thanks `@wheerd`_ for the PR (`#2101`_).
* ``pytest.warns`` now checks for subclass relationship rather than
class equality. Thanks `@lesteve`_ for the PR (`#2166`_)
* ``pytest.raises`` now asserts that the error message matches a text or regex
with the ``match`` keyword argument. Thanks `@Kriechi`_ for the PR.
* ``pytest.param`` can be used to declare test parameter sets with marks and test ids.
Thanks `@RonnyPfannschmidt`_ for the PR.
Changes
-------
* remove all internal uses of pytest_namespace hooks,
this is to prepare the removal of preloadconfig in pytest 4.0
Thanks to `@RonnyPfannschmidt`_ for the PR.
* pytest now warns when a callable ids raises in a parametrized test. Thanks `@fogo`_ for the PR.
* It is now possible to skip test classes from being collected by setting a
``__test__`` attribute to ``False`` in the class body (`#2007`_). Thanks
to `@syre`_ for the report and `@lwm`_ for the PR.
* Change junitxml.py to produce reports that comply with Junitxml schema.
If the same test fails with failure in call and then errors in teardown
we split testcase element into two, one containing the error and the other
the failure. (`#2228`_) Thanks to `@kkoukiou`_ for the PR.
* Testcase reports with a ``url`` attribute will now properly write this to junitxml.
Thanks `@fushi`_ for the PR (`#1874`_).
* Remove common items from dict comparison output when verbosity=1. Also update
the truncation message to make it clearer that pytest truncates all
assertion messages if verbosity < 2 (`#1512`_).
Thanks `@mattduck`_ for the PR
* ``--pdbcls`` no longer implies ``--pdb``. This makes it possible to use
``addopts=--pdbcls=module.SomeClass`` on ``pytest.ini``. Thanks `@davidszotten`_ for
the PR (`#1952`_).
* fix `#2013`_: turn RecordedWarning into ``namedtuple``,
to give it a comprehensible repr while preventing unwarranted modification.
* fix `#2208`_: ensure an iteration limit for _pytest.compat.get_real_func.
Thanks `@RonnyPfannschmidt`_ for the report and PR.
* Hooks are now verified after collection is complete, rather than right after loading installed plugins. This
makes it easy to write hooks for plugins which will be loaded during collection, for example using the
``pytest_plugins`` special variable (`#1821`_).
Thanks `@nicoddemus`_ for the PR.
* Modify ``pytest_make_parametrize_id()`` hook to accept ``argname`` as an
additional parameter.
Thanks `@unsignedint`_ for the PR.
* Add ``venv`` to the default ``norecursedirs`` setting.
Thanks `@The-Compiler`_ for the PR.
* ``PluginManager.import_plugin`` now accepts unicode plugin names in Python 2.
Thanks `@reutsharabani`_ for the PR.
* fix `#2308`_: When using both ``--lf`` and ``--ff``, only the last failed tests are run.
Thanks `@ojii`_ for the PR.
* Replace minor/patch level version numbers in the documentation with placeholders.
This significantly reduces change-noise as different contributors regnerate
the documentation on different platforms.
Thanks `@RonnyPfannschmidt`_ for the PR.
* fix `#2391`_: consider pytest_plugins on all plugin modules
Thanks `@RonnyPfannschmidt`_ for the PR.
Bug Fixes
---------
* Fix ``AttributeError`` on ``sys.stdout.buffer`` / ``sys.stderr.buffer``
while using ``capsys`` fixture in python 3. (`#1407`_).
Thanks to `@asottile`_.
* Change capture.py's ``DontReadFromInput`` class to throw ``io.UnsupportedOperation`` errors rather
than ValueErrors in the ``fileno`` method (`#2276`_).
Thanks `@metasyn`_ and `@vlad-dragos`_ for the PR.
* Fix exception formatting while importing modules when the exception message
contains non-ascii characters (`#2336`_).
Thanks `@fabioz`_ for the report and `@nicoddemus`_ for the PR.
* Added documentation related to issue (`#1937`_)
Thanks `@skylarjhdownes`_ for the PR.
* Allow collecting files with any file extension as Python modules (`#2369`_).
Thanks `@Kodiologist`_ for the PR.
* Show the correct error message when collect "parametrize" func with wrong args (`#2383`_).
Thanks `@The-Compiler`_ for the report and `@robin0371`_ for the PR.

3.0.7 (2017-03-14)
==================
* Fix issue in assertion rewriting breaking due to modules silently discarding
other modules when importing fails
Notably, importing the ``anydbm`` module is fixed. (`#2248`_).
Thanks `@pfhayes`_ for the PR.
* junitxml: Fix problematic case where system-out tag occurred twice per testcase
element in the XML report. Thanks `@kkoukiou`_ for the PR.
* Fix regression, pytest now skips unittest correctly if run with ``--pdb``
(`#2137`_). Thanks to `@gst`_ for the report and `@mbyt`_ for the PR.
* Ignore exceptions raised from descriptors (e.g. properties) during Python test collection (`#2234`_).
Thanks to `@bluetech`_.
* ``--override-ini`` now correctly overrides some fundamental options like ``python_files`` (`#2238`_).
Thanks `@sirex`_ for the report and `@nicoddemus`_ for the PR.
* Replace ``raise StopIteration`` usages in the code by simple ``returns`` to finish generators, in accordance to `PEP-479`_ (`#2160`_).
Thanks `@tgoodlet`_ for the report and `@nicoddemus`_ for the PR.
* Fix internal errors when an unprintable ``AssertionError`` is raised inside a test.
Thanks `@omerhadari`_ for the PR.
* Skipping plugin now also works with test items generated by custom collectors (`#2231`_).
Thanks to `@vidartf`_.
* Fix trailing whitespace in console output if no .ini file presented (`#2281`_). Thanks `@fbjorn`_ for the PR.
* Conditionless ``xfail`` markers no longer rely on the underlying test item
being an instance of ``PyobjMixin``, and can therefore apply to tests not
collected by the built-in python test collector. Thanks `@barneygale`_ for the
PR.

3.0.6 (2017-01-22)
==================
* pytest no longer generates ``PendingDeprecationWarning`` from its own operations, which was introduced by mistake in version ``3.0.5`` (`#2118`_).
Thanks to `@nicoddemus`_ for the report and `@RonnyPfannschmidt`_ for the PR.
* pytest no longer recognizes coroutine functions as yield tests (`#2129`_).
Thanks to `@malinoff`_ for the PR.
* Plugins loaded by the ``PYTEST_PLUGINS`` environment variable are now automatically
considered for assertion rewriting (`#2185`_).
Thanks `@nicoddemus`_ for the PR.
* Improve error message when pytest.warns fails (`#2150`_). The type(s) of the
expected warnings and the list of caught warnings is added to the
error message. Thanks `@lesteve`_ for the PR.
* Fix ``pytester`` internal plugin to work correctly with latest versions of
``zope.interface`` (`#1989`_). Thanks `@nicoddemus`_ for the PR.
* Assert statements of the ``pytester`` plugin again benefit from assertion rewriting (`#1920`_).
Thanks `@RonnyPfannschmidt`_ for the report and `@nicoddemus`_ for the PR.
* Specifying tests with colons like ``test_foo.py::test_bar`` for tests in
subdirectories with ini configuration files now uses the correct ini file
(`#2148`_). Thanks `@pelme`_.
* Fail ``testdir.runpytest().assert_outcomes()`` explicitly if the pytest
terminal output it relies on is missing. Thanks to `@eli-b`_ for the PR.

3.0.5 (2016-12-05)
==================
* Add warning when not passing ``option=value`` correctly to ``-o/--override-ini`` (`#2105`_).
Also improved the help documentation. Thanks to `@mbukatov`_ for the report and
`@lwm`_ for the PR.
* Now ``--confcutdir`` and ``--junit-xml`` are properly validated if they are directories
and filenames, respectively (`#2089`_ and `#2078`_). Thanks to `@lwm`_ for the PR.
* Add hint to error message hinting possible missing ``__init__.py`` (`#478`_). Thanks `@DuncanBetts`_.
* More accurately describe when fixture finalization occurs in documentation (`#687`_). Thanks `@DuncanBetts`_.
* Provide ``:ref:`` targets for ``recwarn.rst`` so we can use intersphinx referencing.
Thanks to `@dupuy`_ for the report and `@lwm`_ for the PR.
* In Python 2, use a simple ``+-`` ASCII string in the string representation of ``pytest.approx`` (for example ``"4 +- 4.0e-06"``)
because it is brittle to handle that in different contexts and representations internally in pytest
which can result in bugs such as `#2111`_. In Python 3, the representation still uses ``±`` (for example ``4 ± 4.0e-06``).
Thanks `@kerrick-lyft`_ for the report and `@nicoddemus`_ for the PR.
* Using ``item.Function``, ``item.Module``, etc., is now issuing deprecation warnings, prefer
``pytest.Function``, ``pytest.Module``, etc., instead (`#2034`_).
Thanks `@nmundar`_ for the PR.
* Fix error message using ``approx`` with complex numbers (`#2082`_).
Thanks `@adler-j`_ for the report and `@nicoddemus`_ for the PR.
* Fixed false-positives warnings from assertion rewrite hook for modules imported more than
once by the ``pytest_plugins`` mechanism.
Thanks `@nicoddemus`_ for the PR.
* Remove an internal cache which could cause hooks from ``conftest.py`` files in
sub-directories to be called in other directories incorrectly (`#2016`_).
Thanks `@d-b-w`_ for the report and `@nicoddemus`_ for the PR.
* Remove internal code meant to support earlier Python 3 versions that produced the side effect
of leaving ``None`` in ``sys.modules`` when expressions were evaluated by pytest (for example passing a condition
as a string to ``pytest.mark.skipif``)(`#2103`_).
Thanks `@jaraco`_ for the report and `@nicoddemus`_ for the PR.
* Cope gracefully with a .pyc file with no matching .py file (`#2038`_). Thanks
`@nedbat`_.

3.0.4 (2016-11-09)
==================
* Import errors when collecting test modules now display the full traceback (`#1976`_).
Thanks `@cwitty`_ for the report and `@nicoddemus`_ for the PR.
* Fix confusing command-line help message for custom options with two or more ``metavar`` properties (`#2004`_).
Thanks `@okulynyak`_ and `@davehunt`_ for the report and `@nicoddemus`_ for the PR.
* When loading plugins, import errors which contain non-ascii messages are now properly handled in Python 2 (`#1998`_).
Thanks `@nicoddemus`_ for the PR.
* Fixed cyclic reference when ``pytest.raises`` is used in context-manager form (`#1965`_). Also as a
result of this fix, ``sys.exc_info()`` is left empty in both context-manager and function call usages.
Previously, ``sys.exc_info`` would contain the exception caught by the context manager,
even when the expected exception occurred.
Thanks `@MSeifert04`_ for the report and the PR.
* Fixed false-positives warnings from assertion rewrite hook for modules that were rewritten but
were later marked explicitly by ``pytest.register_assert_rewrite``
or implicitly as a plugin (`#2005`_).
Thanks `@RonnyPfannschmidt`_ for the report and `@nicoddemus`_ for the PR.
* Report teardown output on test failure (`#442`_).
Thanks `@matclab`_ for the PR.
* Fix teardown error message in generated xUnit XML.
Thanks `@gdyuldin`_ for the PR.
* Properly handle exceptions in ``multiprocessing`` tasks (`#1984`_).
Thanks `@adborden`_ for the report and `@nicoddemus`_ for the PR.
* Clean up unittest TestCase objects after tests are complete (`#1649`_).

3.0.3 (2016-09-28)
==================
* The ``ids`` argument to ``parametrize`` again accepts ``unicode`` strings
in Python 2 (`#1905`_).
Thanks `@philpep`_ for the report and `@nicoddemus`_ for the PR.
* Assertions are now being rewritten for plugins in development mode
(``pip install -e``) (`#1934`_).
Thanks `@nicoddemus`_ for the PR.
* Fix pkg_resources import error in Jython projects (`#1853`_).
Thanks `@raquel-ucl`_ for the PR.
* Got rid of ``AttributeError: 'Module' object has no attribute '_obj'`` exception
in Python 3 (`#1944`_).
Thanks `@axil`_ for the PR.
* Explain a bad scope value passed to ``@fixture`` declarations or
a ``MetaFunc.parametrize()`` call. Thanks `@tgoodlet`_ for the PR.
* This version includes ``pluggy-0.4.0``, which correctly handles
``VersionConflict`` errors in plugins (`#704`_).

3.0.2 (2016-09-01)
==================
* Improve error message when passing non-string ids to ``pytest.mark.parametrize`` (`#1857`_).
Thanks `@okken`_ for the report and `@nicoddemus`_ for the PR.
* Add ``buffer`` attribute to stdin stub class ``pytest.capture.DontReadFromInput``
Thanks `@joguSD`_ for the PR.
* Fix ``UnicodeEncodeError`` when string comparison with unicode has failed. (`#1864`_)
Thanks `@AiOO`_ for the PR.
* ``pytest_plugins`` is now handled correctly if defined as a string (as opposed as
a sequence of strings) when modules are considered for assertion rewriting.
Due to this bug, much more modules were being rewritten than necessary
if a test suite uses ``pytest_plugins`` to load internal plugins (`#1888`_).
Thanks `@jaraco`_ for the report and `@nicoddemus`_ for the PR (`#1891`_).
* Do not call tearDown and cleanups when running tests from
``unittest.TestCase`` subclasses with ``--pdb``
enabled. This allows proper post mortem debugging for all applications
which have significant logic in their tearDown machinery (`#1890`_). Thanks
`@mbyt`_ for the PR.
* Fix use of deprecated ``getfuncargvalue`` method in the internal doctest plugin.

3.0.1 (2016-08-23)
==================
* Fix regression when ``importorskip`` is used at module level (`#1822`_).
Thanks `@jaraco`_ and `@The-Compiler`_ for the report and `@nicoddemus`_ for the PR.
* Fix parametrization scope when session fixtures are used in conjunction
with normal parameters in the same call (`#1832`_).
Thanks `@The-Compiler`_ for the report, `@Kingdread`_ and `@nicoddemus`_ for the PR.
* Fix internal error when parametrizing tests or fixtures using an empty ``ids`` argument (`#1849`_).
Thanks `@OPpuolitaival`_ for the report and `@nicoddemus`_ for the PR.
* Fix loader error when running ``pytest`` embedded in a zipfile.

3.0.0 (2016-08-18)
==================
**Incompatible changes**
A number of incompatible changes were made in this release, with the intent of removing features deprecated for a long
time or change existing behaviors in order to make them less surprising/more useful.
* Reinterpretation mode has now been removed. Only plain and rewrite
mode are available, consequently the ``--assert=reinterp`` option is
no longer available. This also means files imported from plugins or
``conftest.py`` will not benefit from improved assertions by
default, you should use ``pytest.register_assert_rewrite()`` to
explicitly turn on assertion rewriting for those files. Thanks
`@flub`_ for the PR.
* The following deprecated commandline options were removed:
* ``--genscript``: no longer supported;
* ``--no-assert``: use ``--assert=plain`` instead;
* ``--nomagic``: use ``--assert=plain`` instead;
* ``--report``: use ``-r`` instead;
Thanks to `@RedBeardCode`_ for the PR (`#1664`_).
* ImportErrors in plugins now are a fatal error instead of issuing a
pytest warning (`#1479`_). Thanks to `@The-Compiler`_ for the PR.
* Removed support code for Python 3 versions < 3.3 (`#1627`_).
* Removed all ``py.test-X*`` entry points. The versioned, suffixed entry points
were never documented and a leftover from a pre-virtualenv era. These entry
points also created broken entry points in wheels, so removing them also
removes a source of confusion for users (`#1632`_).
Thanks `@obestwalter`_ for the PR.
* ``pytest.skip()`` now raises an error when used to decorate a test function,
as opposed to its original intent (to imperatively skip a test inside a test function). Previously
this usage would cause the entire module to be skipped (`#607`_).
Thanks `@omarkohl`_ for the complete PR (`#1519`_).
* Exit tests if a collection error occurs. A poll indicated most users will hit CTRL-C
anyway as soon as they see collection errors, so pytest might as well make that the default behavior (`#1421`_).
A ``--continue-on-collection-errors`` option has been added to restore the previous behaviour.
Thanks `@olegpidsadnyi`_ and `@omarkohl`_ for the complete PR (`#1628`_).
* Renamed the pytest ``pdb`` module (plugin) into ``debugging`` to avoid clashes with the builtin ``pdb`` module.
* Raise a helpful failure message when requesting a parametrized fixture at runtime,
e.g. with ``request.getfixturevalue``. Previously these parameters were simply
never defined, so a fixture decorated like ``@pytest.fixture(params=[0, 1, 2])``
only ran once (`#460`_).
Thanks to `@nikratio`_ for the bug report, `@RedBeardCode`_ and `@tomviner`_ for the PR.
* ``_pytest.monkeypatch.monkeypatch`` class has been renamed to ``_pytest.monkeypatch.MonkeyPatch``
so it doesn't conflict with the ``monkeypatch`` fixture.
* ``--exitfirst / -x`` can now be overridden by a following ``--maxfail=N``
and is just a synonym for ``--maxfail=1``.
**New Features**
* Support nose-style ``__test__`` attribute on methods of classes,
including unittest-style Classes. If set to ``False``, the test will not be
collected.
* New ``doctest_namespace`` fixture for injecting names into the
namespace in which doctests run.
Thanks `@milliams`_ for the complete PR (`#1428`_).
* New ``--doctest-report`` option available to change the output format of diffs
when running (failing) doctests (implements `#1749`_).
Thanks `@hartym`_ for the PR.
* New ``name`` argument to ``pytest.fixture`` decorator which allows a custom name
for a fixture (to solve the funcarg-shadowing-fixture problem).
Thanks `@novas0x2a`_ for the complete PR (`#1444`_).
* New ``approx()`` function for easily comparing floating-point numbers in
tests.
Thanks `@kalekundert`_ for the complete PR (`#1441`_).
* Ability to add global properties in the final xunit output file by accessing
the internal ``junitxml`` plugin (experimental).
Thanks `@tareqalayan`_ for the complete PR `#1454`_).
* New ``ExceptionInfo.match()`` method to match a regular expression on the
string representation of an exception (`#372`_).
Thanks `@omarkohl`_ for the complete PR (`#1502`_).
* ``__tracebackhide__`` can now also be set to a callable which then can decide
whether to filter the traceback based on the ``ExceptionInfo`` object passed
to it. Thanks `@The-Compiler`_ for the complete PR (`#1526`_).
* New ``pytest_make_parametrize_id(config, val)`` hook which can be used by plugins to provide
friendly strings for custom types.
Thanks `@palaviv`_ for the PR.
* ``capsys`` and ``capfd`` now have a ``disabled()`` context-manager method, which
can be used to temporarily disable capture within a test.
Thanks `@nicoddemus`_ for the PR.
* New cli flag ``--fixtures-per-test``: shows which fixtures are being used
for each selected test item. Features doc strings of fixtures by default.
Can also show where fixtures are defined if combined with ``-v``.
Thanks `@hackebrot`_ for the PR.
* Introduce ``pytest`` command as recommended entry point. Note that ``py.test``
still works and is not scheduled for removal. Closes proposal
`#1629`_. Thanks `@obestwalter`_ and `@davehunt`_ for the complete PR
(`#1633`_).
* New cli flags:
+ ``--setup-plan``: performs normal collection and reports
the potential setup and teardown and does not execute any fixtures and tests;
+ ``--setup-only``: performs normal collection, executes setup and teardown of
fixtures and reports them;
+ ``--setup-show``: performs normal test execution and additionally shows
setup and teardown of fixtures;
+ ``--keep-duplicates``: py.test now ignores duplicated paths given in the command
line. To retain the previous behavior where the same test could be run multiple
times by specifying it in the command-line multiple times, pass the ``--keep-duplicates``
argument (`#1609`_);
Thanks `@d6e`_, `@kvas-it`_, `@sallner`_, `@ioggstream`_ and `@omarkohl`_ for the PRs.
* New CLI flag ``--override-ini``/``-o``: overrides values from the ini file.
For example: ``"-o xfail_strict=True"``'.
Thanks `@blueyed`_ and `@fengxx`_ for the PR.
* New hooks:
+ ``pytest_fixture_setup(fixturedef, request)``: executes fixture setup;
+ ``pytest_fixture_post_finalizer(fixturedef)``: called after the fixture's
finalizer and has access to the fixture's result cache.
Thanks `@d6e`_, `@sallner`_.
* Issue warnings for asserts whose test is a tuple literal. Such asserts will
never fail because tuples are always truthy and are usually a mistake
(see `#1562`_). Thanks `@kvas-it`_, for the PR.
* Allow passing a custom debugger class (e.g. ``--pdbcls=IPython.core.debugger:Pdb``).
Thanks to `@anntzer`_ for the PR.
**Changes**
* Plugins now benefit from assertion rewriting. Thanks
`@sober7`_, `@nicoddemus`_ and `@flub`_ for the PR.
* Change ``report.outcome`` for ``xpassed`` tests to ``"passed"`` in non-strict
mode and ``"failed"`` in strict mode. Thanks to `@hackebrot`_ for the PR
(`#1795`_) and `@gprasad84`_ for report (`#1546`_).
* Tests marked with ``xfail(strict=False)`` (the default) now appear in
JUnitXML reports as passing tests instead of skipped.
Thanks to `@hackebrot`_ for the PR (`#1795`_).
* Highlight path of the file location in the error report to make it easier to copy/paste.
Thanks `@suzaku`_ for the PR (`#1778`_).
* Fixtures marked with ``@pytest.fixture`` can now use ``yield`` statements exactly like
those marked with the ``@pytest.yield_fixture`` decorator. This change renders
``@pytest.yield_fixture`` deprecated and makes ``@pytest.fixture`` with ``yield`` statements
the preferred way to write teardown code (`#1461`_).
Thanks `@csaftoiu`_ for bringing this to attention and `@nicoddemus`_ for the PR.
* Explicitly passed parametrize ids do not get escaped to ascii (`#1351`_).
Thanks `@ceridwen`_ for the PR.
* Fixtures are now sorted in the error message displayed when an unknown
fixture is declared in a test function.
Thanks `@nicoddemus`_ for the PR.
* ``pytest_terminal_summary`` hook now receives the ``exitstatus``
of the test session as argument. Thanks `@blueyed`_ for the PR (`#1809`_).
* Parametrize ids can accept ``None`` as specific test id, in which case the
automatically generated id for that argument will be used.
Thanks `@palaviv`_ for the complete PR (`#1468`_).
* The parameter to xunit-style setup/teardown methods (``setup_method``,
``setup_module``, etc.) is now optional and may be omitted.
Thanks `@okken`_ for bringing this to attention and `@nicoddemus`_ for the PR.
* Improved automatic id generation selection in case of duplicate ids in
parametrize.
Thanks `@palaviv`_ for the complete PR (`#1474`_).
* Now pytest warnings summary is shown up by default. Added a new flag
``--disable-pytest-warnings`` to explicitly disable the warnings summary (`#1668`_).
* Make ImportError during collection more explicit by reminding
the user to check the name of the test module/package(s) (`#1426`_).
Thanks `@omarkohl`_ for the complete PR (`#1520`_).
* Add ``build/`` and ``dist/`` to the default ``--norecursedirs`` list. Thanks
`@mikofski`_ for the report and `@tomviner`_ for the PR (`#1544`_).
* ``pytest.raises`` in the context manager form accepts a custom
``message`` to raise when no exception occurred.
Thanks `@palaviv`_ for the complete PR (`#1616`_).
* ``conftest.py`` files now benefit from assertion rewriting; previously it
was only available for test modules. Thanks `@flub`_, `@sober7`_ and
`@nicoddemus`_ for the PR (`#1619`_).
* Text documents without any doctests no longer appear as "skipped".
Thanks `@graingert`_ for reporting and providing a full PR (`#1580`_).
* Ensure that a module within a namespace package can be found when it
is specified on the command line together with the ``--pyargs``
option. Thanks to `@taschini`_ for the PR (`#1597`_).
* Always include full assertion explanation during assertion rewriting. The previous behaviour was hiding
sub-expressions that happened to be ``False``, assuming this was redundant information.
Thanks `@bagerard`_ for reporting (`#1503`_). Thanks to `@davehunt`_ and
`@tomviner`_ for the PR.
* ``OptionGroup.addoption()`` now checks if option names were already
added before, to make it easier to track down issues like `#1618`_.
Before, you only got exceptions later from ``argparse`` library,
giving no clue about the actual reason for double-added options.
* ``yield``-based tests are considered deprecated and will be removed in pytest-4.0.
Thanks `@nicoddemus`_ for the PR.
* ``[pytest]`` sections in ``setup.cfg`` files should now be named ``[tool:pytest]``
to avoid conflicts with other distutils commands (see `#567`_). ``[pytest]`` sections in
``pytest.ini`` or ``tox.ini`` files are supported and unchanged.
Thanks `@nicoddemus`_ for the PR.
* Using ``pytest_funcarg__`` prefix to declare fixtures is considered deprecated and will be
removed in pytest-4.0 (`#1684`_).
Thanks `@nicoddemus`_ for the PR.
* Passing a command-line string to ``pytest.main()`` is considered deprecated and scheduled
for removal in pytest-4.0. It is recommended to pass a list of arguments instead (`#1723`_).
* Rename ``getfuncargvalue`` to ``getfixturevalue``. ``getfuncargvalue`` is
still present but is now considered deprecated. Thanks to `@RedBeardCode`_ and `@tomviner`_
for the PR (`#1626`_).
* ``optparse`` type usage now triggers DeprecationWarnings (`#1740`_).
* ``optparse`` backward compatibility supports float/complex types (`#457`_).
* Refined logic for determining the ``rootdir``, considering only valid
paths which fixes a number of issues: `#1594`_, `#1435`_ and `#1471`_.
Updated the documentation according to current behavior. Thanks to
`@blueyed`_, `@davehunt`_ and `@matthiasha`_ for the PR.
* Always include full assertion explanation. The previous behaviour was hiding
sub-expressions that happened to be False, assuming this was redundant information.
Thanks `@bagerard`_ for reporting (`#1503`_). Thanks to `@davehunt`_ and
`@tomviner`_ for PR.
* Better message in case of not using parametrized variable (see `#1539`_).
Thanks to `@tramwaj29`_ for the PR.
* Updated docstrings with a more uniform style.
* Add stderr write for ``pytest.exit(msg)`` during startup. Previously the message was never shown.
Thanks `@BeyondEvil`_ for reporting `#1210`_. Thanks to `@JonathonSonesen`_ and
`@tomviner`_ for the PR.
* No longer display the incorrect test deselection reason (`#1372`_).
Thanks `@ronnypfannschmidt`_ for the PR.
* The ``--resultlog`` command line option has been deprecated: it is little used
and there are more modern and better alternatives (see `#830`_).
Thanks `@nicoddemus`_ for the PR.
* Improve error message with fixture lookup errors: add an 'E' to the first
line and '>' to the rest. Fixes `#717`_. Thanks `@blueyed`_ for reporting and
a PR, `@eolo999`_ for the initial PR and `@tomviner`_ for his guidance during
EuroPython2016 sprint.
**Bug Fixes**
* Parametrize now correctly handles duplicated test ids.
* Fix internal error issue when the ``method`` argument is missing for
``teardown_method()`` (`#1605`_).
* Fix exception visualization in case the current working directory (CWD) gets
deleted during testing (`#1235`_). Thanks `@bukzor`_ for reporting. PR by
`@marscher`_.
* Improve test output for logical expression with brackets (`#925`_).
Thanks `@DRMacIver`_ for reporting and `@RedBeardCode`_ for the PR.
* Create correct diff for strings ending with newlines (`#1553`_).
Thanks `@Vogtinator`_ for reporting and `@RedBeardCode`_ and
`@tomviner`_ for the PR.
* ``ConftestImportFailure`` now shows the traceback making it easier to
identify bugs in ``conftest.py`` files (`#1516`_). Thanks `@txomon`_ for
the PR.
* Text documents without any doctests no longer appear as "skipped".
Thanks `@graingert`_ for reporting and providing a full PR (`#1580`_).
* Fixed collection of classes with custom ``__new__`` method.
Fixes `#1579`_. Thanks to `@Stranger6667`_ for the PR.
* Fixed scope overriding inside metafunc.parametrize (`#634`_).
Thanks to `@Stranger6667`_ for the PR.
* Fixed the total tests tally in junit xml output (`#1798`_).
Thanks to `@cryporchild`_ for the PR.
* Fixed off-by-one error with lines from ``request.node.warn``.
Thanks to `@blueyed`_ for the PR.

==================
**Bug Fixes**
* Improve error message when a plugin fails to load.
Thanks `@nicoddemus`_ for the PR.
* Fix (`#1178 <https://github.com/pytest-dev/pytest/issues/1178>`_):
``pytest.fail`` with non-ascii characters raises an internal pytest error.
Thanks `@nicoddemus`_ for the PR.

2.9.0 (2016-02-29)
==================
**New Features**
* New ``pytest.mark.skip`` mark, which unconditionally skips marked tests.
Thanks `@MichaelAquilina`_ for the complete PR (`#1040`_).
* ``--doctest-glob`` may now be passed multiple times in the command-line.
Thanks `@jab`_ and `@nicoddemus`_ for the PR.
* New ``-rp`` and ``-rP`` reporting options give the summary and full output
of passing tests, respectively. Thanks to `@codewarrior0`_ for the PR.
* ``pytest.mark.xfail`` now has a ``strict`` option, which makes ``XPASS``
tests to fail the test suite (defaulting to ``False``). There's also a
``xfail_strict`` ini option that can be used to configure it project-wise.
Thanks `@rabbbit`_ for the request and `@nicoddemus`_ for the PR (`#1355`_).
* ``Parser.addini`` now supports options of type ``bool``.
Thanks `@nicoddemus`_ for the PR.
* New ``ALLOW_BYTES`` doctest option. This strips ``b`` prefixes from byte strings
in doctest output (similar to ``ALLOW_UNICODE``).
Thanks `@jaraco`_ for the request and `@nicoddemus`_ for the PR (`#1287`_).
* Give a hint on ``KeyboardInterrupt`` to use the ``--fulltrace`` option to show the errors.
Fixes `#1366`_.
Thanks to `@hpk42`_ for the report and `@RonnyPfannschmidt`_ for the PR.
* Catch ``IndexError`` exceptions when getting exception source location.
Fixes a pytest internal error for dynamically generated code (fixtures and tests)
where source lines are fake by intention.
**Changes**
* **Important**: `py.code <https://pylib.readthedocs.io/en/latest/code.html>`_ has been
merged into the ``pytest`` repository as ``pytest._code``. This decision
was made because ``py.code`` had very few uses outside ``pytest`` and the
fact that it was in a different repository made it difficult to fix bugs on
its code in a timely manner. The team hopes with this to be able to better
refactor out and improve that code.
This change shouldn't affect users, but it is useful to let users aware
if they encounter any strange behavior.
Keep in mind that the code for ``pytest._code`` is **private** and
**experimental**, so you definitely should not import it explicitly!
Please note that the original ``py.code`` is still available in
`pylib <https://pylib.readthedocs.io>`_.
* ``pytest_enter_pdb`` now optionally receives the pytest config object.
Thanks `@nicoddemus`_ for the PR.
* Removed code and documentation for Python 2.5 or lower versions,
including removal of the obsolete ``_pytest.assertion.oldinterpret`` module.
Thanks `@nicoddemus`_ for the PR (`#1226`_).
* Comparisons now always show up in full when ``CI`` or ``BUILD_NUMBER`` is
found in the environment, even when ``-vv`` isn't used.
Thanks `@The-Compiler`_ for the PR.
* ``--lf`` and ``--ff`` now support long names: ``--last-failed`` and
``--failed-first`` respectively.
Thanks `@MichaelAquilina`_ for the PR.
* Added expected exceptions to ``pytest.raises`` fail message.
* Collection only displays progress ("collecting X items") when in a terminal.
This avoids cluttering the output when using ``--color=yes`` to obtain
colors in CI integrations systems (`#1397`_).
**Bug Fixes**
* The ``-s`` and ``-c`` options should now work under ``xdist``;
``Config.fromdictargs`` now represents its input much more faithfully.
Thanks to `@bukzor`_ for the complete PR (`#680`_).
* Fix (`#1290`_): support Python 3.5's ``@`` operator in assertion rewriting.
Thanks `@Shinkenjoe`_ for report with test case and `@tomviner`_ for the PR.
* Fix formatting utf-8 explanation messages (`#1379`_).
Thanks `@biern`_ for the PR.
* Fix `traceback style docs`_ to describe all of the available options
(auto/long/short/line/native/no), with ``auto`` being the default since v2.6.
Thanks `@hackebrot`_ for the PR.
* Fix (`#1422`_): junit record_xml_property doesn't allow multiple records
with same name.

2.8.1 (2015-09-29)
==================
- fix #1034: Add missing nodeid on pytest_logwarning call in
addhook. Thanks Simon Gomizelj for the PR.
- 'deprecated_call' is now only satisfied with a DeprecationWarning or
PendingDeprecationWarning. Before 2.8.0, it accepted any warning, and 2.8.0
made it accept only DeprecationWarning (but not PendingDeprecationWarning).
Thanks Alex Gaynor for the issue and Eric Hunsberger for the PR.
- fix issue #1073: avoid calling __getattr__ on potential plugin objects.
This fixes an incompatibility with pytest-django. Thanks Andreas Pelme,
Bruno Oliveira and Ronny Pfannschmidt for contributing and Holger Krekel
for the fix.
- Fix issue #704: handle versionconflict during plugin loading more
gracefully. Thanks Bruno Oliveira for the PR.
- Fix issue #1064: ""--junitxml" regression when used with the
"pytest-xdist" plugin, with test reports being assigned to the wrong tests.
Thanks Daniel Grunwald for the report and Bruno Oliveira for the PR.
- (experimental) adapt more SEMVER style versioning and change meaning of
master branch in git repo: "master" branch now keeps the bugfixes, changes
aimed for micro releases. "features" branch will only be released
with minor or major pytest releases.
- Fix issue #766 by removing documentation references to distutils.
Thanks Russel Winder.
- Fix issue #1030: now byte-strings are escaped to produce item node ids

2.8.0 (2015-09-18)
==================
- new ``--lf`` and ``-ff`` options to run only the last failing tests or
"failing tests first" from the last run. This functionality is provided
through porting the formerly external pytest-cache plugin into pytest core.
BACKWARD INCOMPAT: if you used pytest-cache's functionality to persist
data between test runs be aware that we don't serialize sets anymore.
Thanks Ronny Pfannschmidt for most of the merging work.
- "-r" option now accepts "a" to include all possible reports, similar
to passing "fEsxXw" explicitly (isse960).
Thanks Abhijeet Kasurde for the PR.
- avoid python3.5 deprecation warnings by introducing version
specific inspection helpers, thanks Michael Droettboom.

without passing -vv, still show a few lines of the diff.
Thanks Florian Bruhin for the report and Bruno Oliveira for the PR.
- fix issue736: Fix a bug where fixture params would be discarded when combined
with parametrization markers.
Thanks to Markus Unterwaditzer for the PR.
- fix issue710: introduce ALLOW_UNICODE doctest option: when enabled, the
``u`` prefix is stripped from unicode strings in expected doctest output. This
allows doctests which use unicode to run in Python 2 and 3 unchanged.
Thanks Jason R. Coombs for the report and Bruno Oliveira for the PR.
- parametrize now also generates meaningful test IDs for enum, regex and class
objects (as opposed to class instances).
Thanks to Florian Bruhin for the PR.
- Add 'warns' to assert that warnings are thrown (like 'raises').
Thanks to Eric Hunsberger for the PR.
- Fix issue683: Do not apply an already applied mark. Thanks ojake for the PR.
- Deal with capturing failures better so fewer exceptions get lost to
/dev/null. Thanks David Szotten for the PR.
- fix issue730: deprecate and warn about the --genscript option.
Thanks Ronny Pfannschmidt for the report and Christian Pommranz for the PR.
- fix issue751: multiple parametrize with ids bug if it parametrizes class with
two or more test methods. Thanks Sergey Chipiga for reporting and Jan
Bednarik for PR.
- fix issue82: avoid loading conftest files from setup.cfg/pytest.ini/tox.ini
files and upwards by default (--confcutdir can still be set to override this).
Thanks Bruno Oliveira for the PR.
- fix issue768: docstrings found in python modules were not setting up session
fixtures. Thanks Jason R. Coombs for reporting and Bruno Oliveira for the PR.
- added ``tmpdir_factory``, a session-scoped fixture that can be used to create
directories under the base temporary directory. Previously this object was
installed as a ``_tmpdirhandler`` attribute of the ``config`` object, but now it
is part of the official API and using ``config._tmpdirhandler`` is
deprecated.
Thanks Bruno Oliveira for the PR.
- fix issue808: pytest's internal assertion rewrite hook now implements the
optional PEP302 get_data API so tests can access data files next to them.
Thanks xmo-odoo for request and example and Bruno Oliveira for
the PR.
- rootdir and inifile are now displayed during usage errors to help
users diagnose problems such as unexpected ini files which add
unknown options being picked up by pytest. Thanks to Pavel Savchenko for
bringing the problem to attention in #821 and Bruno Oliveira for the PR.
- Summary bar now is colored yellow for warning
situations such as: all tests either were skipped or xpass/xfailed,
or no tests were run at all (this is a partial fix for issue500).
- fix issue812: pytest now exits with status code 5 in situations where no
tests were run at all, such as the directory given in the command line does
not contain any tests or as result of a command line option filters
all out all tests (-k for example).
Thanks Eric Siegerman (issue812) and Bruno Oliveira for the PR.
- Summary bar now is colored yellow for warning
situations such as: all tests either were skipped or xpass/xfailed,
or no tests were run at all (related to issue500).
Thanks Eric Siegerman.
- New ``testpaths`` ini option: list of directories to search for tests
when executing pytest from the root directory. This can be used
to speed up test collection when a project has well specified directories
for tests, being usually more practical than configuring norecursedirs for
all directories that do not contain tests.
Thanks to Adrian for idea (#694) and Bruno Oliveira for the PR.
- fix issue713: JUnit XML reports for doctest failures.
Thanks Punyashloka Biswal.
- fix issue970: internal pytest warnings now appear as "pytest-warnings" in
the terminal instead of "warnings", so it is clear for users that those
warnings are from pytest and not from the builtin "warnings" module.
Thanks Bruno Oliveira.
- Include setup and teardown in junitxml test durations.
Thanks Janne Vanhala.
- fix issue735: assertion failures on debug versions of Python 3.4+
- new option ``--import-mode`` to allow to change test module importing
behaviour to append to sys.path instead of prepending. This better allows
to run test modules against installed versions of a package even if the
package under test has the same import root. In this example::
testing/__init__.py
testing/test_pkg_under_test.py
pkg_under_test/
the tests will run against the installed version
of pkg_under_test when ``--import-mode=append`` is used whereas
by default they would always pick up the local version. Thanks Holger Krekel.
- pytester: add method ``TmpTestdir.delete_loaded_modules()``, and call it
from ``inline_run()`` to allow temporary modules to be reloaded.
Thanks Eduardo Schettino.
- internally refactor pluginmanager API and code so that there
is a clear distinction between a pytest-agnostic rather simple
pluginmanager and the PytestPluginManager which adds a lot of
behaviour, among it handling of the local conftest files.
In terms of documented methods this is a backward compatible
change but it might still break 3rd party plugins which relied on
details like especially the pluginmanager.add_shutdown() API.
Thanks Holger Krekel.
- pluginmanagement: introduce ``pytest.hookimpl`` and
``pytest.hookspec`` decorators for setting impl/spec
specific parameters. This substitutes the previous
now deprecated use of ``pytest.mark`` which is meant to
contain markers for test functions only.
- write/refine docs for "writing plugins" which now have their
own page and are separate from the "using/installing plugins`` page.
- fix issue732: properly unregister plugins from any hook calling
sites allowing to have temporary plugins during test execution.
- deprecate and warn about ``__multicall__`` argument in hook
implementations. Use the ``hookwrapper`` mechanism instead already
introduced with pytest-2.7.
- speed up pytest's own test suite considerably by using inprocess
tests by default (testrun can be modified with --runpytest=subprocess
to create subprocesses in many places instead). The main
APIs to run pytest in a test is "runpytest()" or "runpytest_subprocess"
and "runpytest_inprocess" if you need a particular way of running
the test. In all cases you get back a RunResult but the inprocess
one will also have a "reprec" attribute with the recorded events/reports.
- fix monkeypatch.setattr("x.y", raising=False) to actually not raise
if "y" is not a pre-existing attribute. Thanks Florian Bruhin.
- fix issue741: make running output from testdir.run copy/pasteable
Thanks Bruno Oliveira.
- add a new ``--noconftest`` argument which ignores all ``conftest.py`` files.
- add ``file`` and ``line`` attributes to JUnit-XML output.
- fix issue890: changed extension of all documentation files from ``txt`` to
``rst``. Thanks to Abhijeet for the PR.
- fix issue714: add ability to apply indirect=True parameter on particular argnames.
Thanks Elizaveta239.
- fix issue890: changed extension of all documentation files from ``txt`` to
``rst``. Thanks to Abhijeet for the PR.
- fix issue957: "# doctest: SKIP" option will now register doctests as SKIPPED
rather than PASSED.
Thanks Thomas Grainger for the report and Bruno Oliveira for the PR.
- issue951: add new record_xml_property fixture, that supports logging
additional information on xml output. Thanks David Diaz for the PR.
- issue949: paths after normal options (for example ``-s``, ``-v``, etc) are now
properly used to discover ``rootdir`` and ``ini`` files.
Thanks Peter Lauri for the report and Bruno Oliveira for the PR.
2.7.3 (2015-09-15)
==================
- Allow 'dev', 'rc', or other non-integer version strings in ``importorskip``.
Thanks to Eric Hunsberger for the PR.
- fix issue856: consider --color parameter in all outputs (for example
--fixtures). Thanks Barney Gale for the report and Bruno Oliveira for the PR.
- fix issue855: passing str objects as ``plugins`` argument to pytest.main
is now interpreted as a module name to be imported and registered as a
plugin, instead of silently having no effect.
Thanks xmo-odoo for the report and Bruno Oliveira for the PR.
- fix issue744: fix for ast.Call changes in Python 3.5+. Thanks
Guido van Rossum, Matthias Bussonnier, Stefan Zimmermann and
Thomas Kluyver.
- fix issue842: applying markers in classes no longer propagate this markers
to superclasses which also have markers.
Thanks xmo-odoo for the report and Bruno Oliveira for the PR.
- preserve warning functions after call to pytest.deprecated_call. Thanks
Pieter Mulder for PR.
- fix issue854: autouse yield_fixtures defined as class members of
unittest.TestCase subclasses now work as expected.
Thannks xmo-odoo for the report and Bruno Oliveira for the PR.
- fix issue833: --fixtures now shows all fixtures of collected test files, instead of just the
fixtures declared on the first one.
Thanks Florian Bruhin for reporting and Bruno Oliveira for the PR.
- fix issue863: skipped tests now report the correct reason when a skip/xfail
condition is met when using multiple markers.
Thanks Raphael Pierzina for reporting and Bruno Oliveira for the PR.
- optimized tmpdir fixture initialization, which should make test sessions
faster (specially when using pytest-xdist). The only visible effect
is that now pytest uses a subdirectory in the $TEMP directory for all
directories created by this fixture (defaults to $TEMP/pytest-$USER).
Thanks Bruno Oliveira for the PR.
2.7.2 (2015-06-23)
==================
- fix issue767: pytest.raises value attribute does not contain the exception
instance on Python 2.6. Thanks Eric Siegerman for providing the test
case and Bruno Oliveira for PR.
- Automatically create directory for junitxml and results log.
Thanks Aron Curzon.
- fix issue713: JUnit XML reports for doctest failures.
Thanks Punyashloka Biswal.
- fix issue735: assertion failures on debug versions of Python 3.4+
Thanks Benjamin Peterson.
- fix issue114: skipif marker reports to internal skipping plugin;
Thanks Floris Bruynooghe for reporting and Bruno Oliveira for the PR.
- fix issue748: unittest.SkipTest reports to internal pytest unittest plugin.
Thanks Thomas De Schampheleire for reporting and Bruno Oliveira for the PR.
- fix issue718: failed to create representation of sets containing unsortable
elements in python 2. Thanks Edison Gustavo Muenz.
- fix issue756, fix issue752 (and similar issues): depend on py-1.4.29
which has a refined algorithm for traceback generation.
2.7.1 (2015-05-19)
==================
- fix issue731: do not get confused by the braces which may be present
and unbalanced in an object's repr while collapsing False
explanations. Thanks Carl Meyer for the report and test case.
- fix issue553: properly handling inspect.getsourcelines failures in
FixtureLookupError which would lead to an internal error,
obfuscating the original problem. Thanks talljosh for initial
diagnose/patch and Bruno Oliveira for final patch.
- fix issue660: properly report scope-mismatch-access errors
independently from ordering of fixture arguments. Also
avoid the pytest internal traceback which does not provide
information to the user. Thanks Holger Krekel.
- streamlined and documented release process. Also all versions
(in setup.py and documentation generation) are now read
from _pytest/__init__.py. Thanks Holger Krekel.
- fixed docs to remove the notion that yield-fixtures are experimental.
They are here to stay :) Thanks Bruno Oliveira.
- Support building wheels by using environment markers for the
requirements. Thanks Ionel Maries Cristian.
- fixed regression to 2.6.4 which surfaced e.g. in lost stdout capture printing
when tests raised SystemExit. Thanks Holger Krekel.
- reintroduced _pytest fixture of the pytester plugin which is used
at least by pytest-xdist.
2.7.0 (2015-03-26)
==================
- fix issue435: make reload() work when assert rewriting is active.
Thanks Daniel Hahler.
- fix issue616: conftest.py files and their contained fixutres are now
properly considered for visibility, independently from the exact
current working directory and test arguments that are used.
Many thanks to Eric Siegerman and his PR235 which contains
systematic tests for conftest visibility and now passes.
This change also introduces the concept of a ``rootdir`` which
is printed as a new pytest header and documented in the pytest
customize web page.
- change reporting of "diverted" tests, i.e. tests that are collected
in one file but actually come from another (e.g. when tests in a test class
come from a base class in a different file). We now show the nodeid
and indicate via a postfix the other file.
- add ability to set command line options by environment variable PYTEST_ADDOPTS.
- added documentation on the new pytest-dev teams on bitbucket and
github. See https://pytest.org/latest/contributing.html .
Thanks to Anatoly for pushing and initial work on this.
- fix issue650: new option ``--docttest-ignore-import-errors`` which
will turn import errors in doctests into skips. Thanks Charles Cloud
for the complete PR.
- fix issue655: work around different ways that cause python2/3
to leak sys.exc_info into fixtures/tests causing failures in 3rd party code
- fix issue615: assertion rewriting did not correctly escape % signs
when formatting boolean operations, which tripped over mixing
booleans with modulo operators. Thanks to Tom Viner for the report,
triaging and fix.
- implement issue351: add ability to specify parametrize ids as a callable
to generate custom test ids. Thanks Brianna Laugher for the idea and
implementation.
- introduce and document new hookwrapper mechanism useful for plugins
which want to wrap the execution of certain hooks for their purposes.
This supersedes the undocumented ``__multicall__`` protocol which
pytest itself and some external plugins use. Note that pytest-2.8
is scheduled to drop supporting the old ``__multicall__``
and only support the hookwrapper protocol.
- majorly speed up invocation of plugin hooks
- use hookwrapper mechanism in builtin pytest plugins.
- add a doctest ini option for doctest flags, thanks Holger Peters.
- add note to docs that if you want to mark a parameter and the
parameter is a callable, you also need to pass in a reason to disambiguate
it from the "decorator" case. Thanks Tom Viner.
- "python_classes" and "python_functions" options now support glob-patterns
for test discovery, as discussed in issue600. Thanks Ldiary Translations.
- allow to override parametrized fixtures with non-parametrized ones and vice versa (bubenkoff).
- fix issue463: raise specific error for 'parameterize' misspelling (pfctdayelise).
- On failure, the ``sys.last_value``, ``sys.last_type`` and
``sys.last_traceback`` are set, so that a user can inspect the error
via postmortem debugging (almarklein).
2.6.4 (2014-10-24)
==================
- Improve assertion failure reporting on iterables, by using ndiff and
pprint.
- removed outdated japanese docs from source tree.
- docs for "pytest_addhooks" hook. Thanks Bruno Oliveira.
- updated plugin index docs. Thanks Bruno Oliveira.
- fix issue557: with "-k" we only allow the old style "-" for negation
at the beginning of strings and even that is deprecated. Use "not" instead.
This should allow to pick parametrized tests where "-" appeared in the parameter.
- fix issue604: Escape % character in the assertion message.
- fix issue620: add explanation in the --genscript target about what
the binary blob means. Thanks Dinu Gherman.
- fix issue614: fixed pastebin support.
- fix issue620: add explanation in the --genscript target about what
the binary blob means. Thanks Dinu Gherman.
- fix issue614: fixed pastebin support.
2.6.3 (2014-09-24)
==================
- fix issue575: xunit-xml was reporting collection errors as failures
instead of errors, thanks Oleg Sinyavskiy.
- fix issue582: fix setuptools example, thanks Laszlo Papp and Ronny
Pfannschmidt.
- Fix infinite recursion bug when pickling capture.EncodedFile, thanks
Uwe Schmitt.
- fix issue589: fix bad interaction with numpy and others when showing
exceptions. Check for precise "maximum recursion depth exceed" exception
instead of presuming any RuntimeError is that one (implemented in py
dep). Thanks Charles Cloud for analysing the issue.
- fix conftest related fixture visibility issue: when running with a
CWD outside of a test package pytest would get fixture discovery wrong.
Thanks to Wolfgang Schnerring for figuring out a reproducible example.
- Introduce pytest_enter_pdb hook (needed e.g. by pytest_timeout to cancel the
timeout when interactively entering pdb). Thanks Wolfgang Schnerring.
- check xfail/skip also with non-python function test items. Thanks
Floris Bruynooghe.
2.6.2 (2014-09-05)
==================
- Added function pytest.freeze_includes(), which makes it easy to embed
pytest into executables using tools like cx_freeze.
See docs for examples and rationale. Thanks Bruno Oliveira.
- Improve assertion rewriting cache invalidation precision.
- fixed issue561: adapt autouse fixture example for python3.
- fixed issue453: assertion rewriting issue with __repr__ containing
"\n{", "\n}" and "\n~".
- fix issue560: correctly display code if an "else:" or "finally:" is
followed by statements on the same line.
- Fix example in monkeypatch documentation, thanks t-8ch.
- fix issue572: correct tmpdir doc example for python3.
- Do not mark as universal wheel because Python 2.6 is different from
other builds due to the extra argparse dependency. Fixes issue566.
Thanks sontek.
- Implement issue549: user-provided assertion messages now no longer
replace the py.test introspection message but are shown in addition
to them.
2.6.1 (2014-08-07)
==================
- No longer show line numbers in the --verbose output, the output is now
purely the nodeid. The line number is still shown in failure reports.
Thanks Floris Bruynooghe.
- fix issue437 where assertion rewriting could cause pytest-xdist slaves
to collect different tests. Thanks Bruno Oliveira.
- fix issue555: add "errors" attribute to capture-streams to satisfy
some distutils and possibly other code accessing sys.stdout.errors.
- fix issue547 capsys/capfd also work when output capturing ("-s") is disabled.
- address issue170: allow pytest.mark.xfail(...) to specify expected exceptions via
an optional "raises=EXC" argument where EXC can be a single exception
or a tuple of exception classes. Thanks David Mohr for the complete
PR.
- fix integration of pytest with unittest.mock.patch decorator when
it uses the "new" argument. Thanks Nicolas Delaby for test and PR.
- fix issue with detecting conftest files if the arguments contain
"::" node id specifications (copy pasted from "-v" output)
- fix issue544 by only removing "@NUM" at the end of "::" separated parts
and if the part has a ".py" extension
- don't use py.std import helper, rather import things directly.
Thanks Bruno Oliveira.

===
- Cache exceptions from fixtures according to their scope (issue 467).
- fix issue537: Avoid importing old assertion reinterpretation code by default.
- fix issue364: shorten and enhance tracebacks representation by default.
The new "--tb=auto" option (default) will only display long tracebacks
for the first and last entry. You can get the old behaviour of printing
all entries as long entries with "--tb=long". Also short entries by
default are now printed very similarly to "--tb=native" ones.
- fix issue514: teach assertion reinterpretation about private class attributes
- change -v output to include full node IDs of tests. Users can copy
a node ID from a test run, including line number, and use it as a
positional argument in order to run only a single test.
- fix issue 475: fail early and comprehensible if calling
pytest.raises with wrong exception type.
- fix issue516: tell in getting-started about current dependencies.
- cleanup setup.py a bit and specify supported versions. Thanks Jurko
Gospodnetic for the PR.
- change XPASS colour to yellow rather then red when tests are run
with -v.
- fix issue473: work around mock putting an unbound method into a class
dict when double-patching.
- fix issue498: if a fixture finalizer fails, make sure that
the fixture is still invalidated.
- fix issue453: the result of the pytest_assertrepr_compare hook now gets
it's newlines escaped so that format_exception does not blow up.
- internal new warning system: pytest will now produce warnings when
it detects oddities in your test collection or execution.
Warnings are ultimately sent to a new pytest_logwarning hook which is
currently only implemented by the terminal plugin which displays
warnings in the summary line and shows more details when -rw (report on
warnings) is specified.
- change skips into warnings for test classes with an __init__ and
callables in test modules which look like a test but are not functions.
- fix issue436: improved finding of initial conftest files from command
line arguments by using the result of parse_known_args rather than
the previous flaky heuristics. Thanks Marc Abramowitz for tests
and initial fixing approaches in this area.
- fix issue #479: properly handle nose/unittest(2) SkipTest exceptions
during collection/loading of test modules. Thanks to Marc Schlaich
for the complete PR.
- fix issue490: include pytest_load_initial_conftests in documentation
and improve docstring.
- fix issue472: clarify that ``pytest.config.getvalue()`` cannot work
if it's triggered ahead of command line parsing.
- merge PR123: improved integration with mock.patch decorator on tests.
- fix issue412: messing with stdout/stderr FD-level streams is now
captured without crashes.
- fix issue483: trial/py33 works now properly. Thanks Daniel Grana for PR.
- improve example for pytest integration with "python setup.py test"
which now has a generic "-a" or "--pytest-args" option where you
can pass additional options as a quoted string. Thanks Trevor Bekolay.
- simplified internal capturing mechanism and made it more robust
against tests or setups changing FD1/FD2, also better integrated
now with pytest.pdb() in single tests.
- improvements to pytest's own test-suite leakage detection, courtesy of PRs
from Marc Abramowitz
- fix issue492: avoid leak in test_writeorg. Thanks Marc Abramowitz.
- fix issue493: don't run tests in doc directory with ``python setup.py test``
(use tox -e doctesting for that)
- fix issue486: better reporting and handling of early conftest loading failures
- some cleanup and simplification of internal conftest handling.
- work a bit harder to break reference cycles when catching exceptions.
Thanks Jurko Gospodnetic.
- fix issue443: fix skip examples to use proper comparison. Thanks Alex
Groenholm.
- support nose-style ``__test__`` attribute on modules, classes and
functions, including unittest-style Classes. If set to False, the
test will not be collected.
- fix issue512: show "<notset>" for arguments which might not be set
in monkeypatch plugin. Improves output in documentation.
2.5.2 (2014-01-29)
==================
- fix issue409 -- better interoperate with cx_freeze by not
trying to import from collections.abc which causes problems
for py27/cx_freeze. Thanks Wolfgang L. for reporting and tracking it down.
- fixed docs and code to use "pytest" instead of "py.test" almost everywhere.
Thanks Jurko Gospodnetic for the complete PR.
- fix issue425: mention at end of "py.test -h" that --markers
and --fixtures work according to specified test path (or current dir)
- fix issue413: exceptions with unicode attributes are now printed
correctly also on python2 and with pytest-xdist runs. (the fix
requires py-1.4.20)
- copy, cleanup and integrate py.io capture
from pylib 1.4.20.dev2 (rev 13d9af95547e)
- address issue416: clarify docs as to conftest.py loading semantics
- fix issue429: comparing byte strings with non-ascii chars in assert
expressions now work better. Thanks Floris Bruynooghe.
- make capfd/capsys.capture private, its unused and shouldn't be exposed
2.5.1 (2013-12-17)
==================
- merge new documentation styling PR from Tobias Bieniek.
- fix issue403: allow parametrize of multiple same-name functions within
a collection node. Thanks Andreas Kloeckner and Alex Gaynor for reporting
and analysis.
- Allow parameterized fixtures to specify the ID of the parameters by
adding an ids argument to pytest.fixture() and pytest.yield_fixture().
Thanks Floris Bruynooghe.
- fix issue404 by always using the binary xml escape in the junitxml
plugin. Thanks Ronny Pfannschmidt.
- fix issue407: fix addoption docstring to point to argparse instead of
optparse. Thanks Daniel D. Wright.
2.5.0 (2013-12-12)
==================
- dropped python2.5 from automated release testing of pytest itself
which means it's probably going to break soon (but still works
with this release we believe).
- simplified and fixed implementation for calling finalizers when
parametrized fixtures or function arguments are involved. finalization
is now performed lazily at setup time instead of in the "teardown phase".
While this might sound odd at first, it helps to ensure that we are
correctly handling setup/teardown even in complex code. User-level code
should not be affected unless it's implementing the pytest_runtest_teardown
hook and expecting certain fixture instances are torn down within (very
unlikely and would have been unreliable anyway).
- PR90: add --color=yes|no|auto option to force terminal coloring
mode ("auto" is default). Thanks Marc Abramowitz.
- fix issue319 - correctly show unicode in assertion errors. Many
thanks to Floris Bruynooghe for the complete PR. Also means
we depend on py>=1.4.19 now.
- fix issue396 - correctly sort and finalize class-scoped parametrized
tests independently from number of methods on the class.
- refix issue323 in a better way -- parametrization should now never
cause Runtime Recursion errors because the underlying algorithm
for re-ordering tests per-scope/per-fixture is not recursive
anymore (it was tail-call recursive before which could lead
to problems for more than >966 non-function scoped parameters).
- fix issue290 - there is preliminary support now for parametrizing
with repeated same values (sometimes useful to test if calling
a second time works as with the first time).
- close issue240 - document precisely how pytest module importing
works, discuss the two common test directory layouts, and how it
interacts with PEP420-namespace packages.
- fix issue246 fix finalizer order to be LIFO on independent fixtures
depending on a parametrized higher-than-function scoped fixture.
(was quite some effort so please bear with the complexity of this sentence :)
Thanks Ralph Schmitt for the precise failure example.
- fix issue244 by implementing special index for parameters to only use
indices for paramentrized test ids
- fix issue287 by running all finalizers but saving the exception
from the first failing finalizer and re-raising it so teardown will
still have failed. We reraise the first failing exception because
it might be the cause for other finalizers to fail.
- fix ordering when mock.patch or other standard decorator-wrappings
are used with test methods. This fixues issue346 and should
help with random "xdist" collection failures. Thanks to
Ronny Pfannschmidt and Donald Stufft for helping to isolate it.
- fix issue357 - special case "-k" expressions to allow for
filtering with simple strings that are not valid python expressions.
Examples: "-k 1.3" matches all tests parametrized with 1.3.
"-k None" filters all tests that have "None" in their name
and conversely "-k 'not None'".
Previously these examples would raise syntax errors.
- fix issue384 by removing the trial support code
since the unittest compat enhancements allow
trial to handle it on its own
- don't hide an ImportError when importing a plugin produces one.
fixes issue375.
- fix issue275 - allow usefixtures and autouse fixtures
for running doctest text files.
- fix issue380 by making --resultlog only rely on longrepr instead
of the "reprcrash" attribute which only exists sometimes.
- address issue122: allow @pytest.fixture(params=iterator) by exploding
into a list early on.
- fix pexpect-3.0 compatibility for pytest's own tests.
(fixes issue386)
- allow nested parametrize-value markers, thanks James Lan for the PR.
- fix unicode handling with new monkeypatch.setattr(import_path, value)
API. Thanks Rob Dennis. Fixes issue371.
- fix unicode handling with junitxml, fixes issue368.
- In assertion rewriting mode on Python 2, fix the detection of coding
cookies. See issue #330.
- make "--runxfail" turn imperative pytest.xfail calls into no ops
(it already did neutralize pytest.mark.xfail markers)
- refine pytest / pkg_resources interactions: The AssertionRewritingHook
PEP302 compliant loader now registers itself with setuptools/pkg_resources
properly so that the pkg_resources.resource_stream method works properly.
Fixes issue366. Thanks for the investigations and full PR to Jason R. Coombs.
- pytestconfig fixture is now session-scoped as it is the same object during the
whole test run. Fixes issue370.
- avoid one surprising case of marker malfunction/confusion::
@pytest.mark.some(lambda arg: ...)
def test_function():
would not work correctly because pytest assumes @pytest.mark.some
gets a function to be decorated already. We now at least detect if this
arg is a lambda and thus the example will work. Thanks Alex Gaynor
for bringing it up.
- xfail a test on pypy that checks wrong encoding/ascii (pypy does
not error out). fixes issue385.
- internally make varnames() deal with classes's __init__,
although it's not needed by pytest itself atm. Also
fix caching. Fixes issue376.
- fix issue221 - handle importing of namespace-package with no
__init__.py properly.
- refactor internal FixtureRequest handling to avoid monkeypatching.
One of the positive user-facing effects is that the "request" object
can now be used in closures.
- fixed version comparison in pytest.importskip(modname, minverstring)
- fix issue377 by clarifying in the nose-compat docs that pytest
does not duplicate the unittest-API into the "plain" namespace.
- fix verbose reporting for @mock'd test functions
2.4.2 (2013-10-04)
==================
- on Windows require colorama and a newer py lib so that py.io.TerminalWriter()
now uses colorama instead of its own ctypes hacks. (fixes issue365)
thanks Paul Moore for bringing it up.
- fix "-k" matching of tests where "repr" and "attr" and other names would
cause wrong matches because of an internal implementation quirk
(don't ask) which is now properly implemented. fixes issue345.
- avoid tmpdir fixture to create too long filenames especially
when parametrization is used (issue354)
- fix pytest-pep8 and pytest-flakes / pytest interactions
(collection names in mark plugin was assuming an item always
has a function which is not true for those plugins etc.)
Thanks Andi Zeidler.
- introduce node.get_marker/node.add_marker API for plugins
like pytest-pep8 and pytest-flakes to avoid the messy
details of the node.keywords pseudo-dicts. Adapted
docs.
- remove attempt to "dup" stdout at startup as it's icky.
the normal capturing should catch enough possibilities
of tests messing up standard FDs.
- add pluginmanager.do_configure(config) as a link to
config.do_configure() for plugin-compatibility
2.4.1 (2013-10-02)
==================
- When using parser.addoption() unicode arguments to the
"type" keyword should also be converted to the respective types.
thanks Floris Bruynooghe, @dnozay. (fixes issue360 and issue362)
- fix dotted filename completion when using argcomplete
thanks Anthon van der Neuth. (fixes issue361)
- fix regression when a 1-tuple ("arg",) is used for specifying
parametrization (the values of the parametrization were passed
nested in a tuple). Thanks Donald Stufft.
- merge doc typo fixes, thanks Andy Dirnberger
2.4
===
known incompatibilities:
- if calling --genscript from python2.7 or above, you only get a
standalone script which works on python2.7 or above. Use Python2.6
to also get a python2.5 compatible version.
- all xunit-style teardown methods (nose-style, pytest-style,
unittest-style) will not be called if the corresponding setup method failed,
see issue322 below.
- the pytest_plugin_unregister hook wasn't ever properly called
and there is no known implementation of the hook - so it got removed.
- pytest.fixture-decorated functions cannot be generators (i.e. use
yield) anymore. This change might be reversed in 2.4.1 if it causes
unforeseen real-life issues. However, you can always write and return
an inner function/generator and change the fixture consumer to iterate
over the returned generator. This change was done in lieu of the new
``pytest.yield_fixture`` decorator, see below.
new features:
- experimentally introduce a new ``pytest.yield_fixture`` decorator
which accepts exactly the same parameters as pytest.fixture but
mandates a ``yield`` statement instead of a ``return statement`` from
fixture functions. This allows direct integration with "with-style"
context managers in fixture functions and generally avoids registering
of finalization callbacks in favour of treating the "after-yield" as
teardown code. Thanks Andreas Pelme, Vladimir Keleshev, Floris
Bruynooghe, Ronny Pfannschmidt and many others for discussions.
- allow boolean expression directly with skipif/xfail
if a "reason" is also specified. Rework skipping documentation
to recommend "condition as booleans" because it prevents surprises
when importing markers between modules. Specifying conditions
as strings will remain fully supported.
- reporting: color the last line red or green depending if
failures/errors occurred or everything passed. thanks Christian
Theunert.
- make "import pdb ; pdb.set_trace()" work natively wrt capturing (no
"-s" needed anymore), making ``pytest.set_trace()`` a mere shortcut.
- fix issue181: --pdb now also works on collect errors (and
on internal errors) . This was implemented by a slight internal
refactoring and the introduction of a new hook
``pytest_exception_interact`` hook (see next item).
- fix issue341: introduce new experimental hook for IDEs/terminals to
intercept debugging: ``pytest_exception_interact(node, call, report)``.
- new monkeypatch.setattr() variant to provide a shorter
invocation for patching out classes/functions from modules:
monkeypatch.setattr("requests.get", myfunc)
will replace the "get" function of the "requests" module with ``myfunc``.
- fix issue322: tearDownClass is not run if setUpClass failed. Thanks
Mathieu Agopian for the initial fix. Also make all of pytest/nose
finalizer mimic the same generic behaviour: if a setupX exists and
fails, don't run teardownX. This internally introduces a new method
"node.addfinalizer()" helper which can only be called during the setup
phase of a node.
- simplify pytest.mark.parametrize() signature: allow to pass a
CSV-separated string to specify argnames. For example:
``pytest.mark.parametrize("input,expected", [(1,2), (2,3)])``
works as well as the previous:
``pytest.mark.parametrize(("input", "expected"), ...)``.
- add support for setUpModule/tearDownModule detection, thanks Brian Okken.
- integrate tab-completion on options through use of "argcomplete".
Thanks Anthon van der Neut for the PR.
- change option names to be hyphen-separated long options but keep the
old spelling backward compatible. py.test -h will only show the
hyphenated version, for example "--collect-only" but "--collectonly"
will remain valid as well (for backward-compat reasons). Many thanks to
Anthon van der Neut for the implementation and to Hynek Schlawack for
pushing us.
- fix issue 308 - allow to mark/xfail/skip individual parameter sets
when parametrizing. Thanks Brianna Laugher.
- call new experimental pytest_load_initial_conftests hook to allow
3rd party plugins to do something before a conftest is loaded.
Bug fixes:
- fix issue358 - capturing options are now parsed more properly
by using a new parser.parse_known_args method.
- pytest now uses argparse instead of optparse (thanks Anthon) which
means that "argparse" is added as a dependency if installing into python2.6
environments or below.
- fix issue333: fix a case of bad unittest/pytest hook interaction.
- PR27: correctly handle nose.SkipTest during collection. Thanks
Antonio Cuni, Ronny Pfannschmidt.
- fix issue355: junitxml puts name="pytest" attribute to testsuite tag.
- fix issue336: autouse fixture in plugins should work again.

Brianna Laugher and Mathieu Agopian.
- fix issue317: assertion rewriter support for the is_package method
- fix issue335: document py.code.ExceptionInfo() object returned
from pytest.raises(), thanks Mathieu Agopian.
- remove implicit distribute_setup support from setup.py.
- fix issue305: ignore any problems when writing pyc files.
- SO-17664702: call fixture finalizers even if the fixture function
partially failed (finalizers would not always be called before)
- fix issue320 - fix class scope for fixtures when mixed with
module-level functions. Thanks Anatloy Bubenkoff.
- you can specify "-q" or "-qq" to get different levels of "quieter"
reporting (thanks Katarzyna Jachim)
- fix issue300 - Fix order of conftest loading when starting py.test
in a subdirectory.
- fix issue323 - sorting of many module-scoped arg parametrizations
- make sessionfinish hooks execute with the same cwd-context as at
session start (helps fix plugin behaviour which write output files
with relative path such as pytest-cov)
- fix issue316 - properly reference collection hooks in docs
- fix issue 306 - cleanup of -k/-m options to only match markers/test
names/keywords respectively. Thanks Wouter van Ackooy.
- improved doctest counting for doctests in python modules --
files without any doctest items will not show up anymore
and doctest examples are counted as separate test items.
thanks Danilo Bellini.
- fix issue245 by depending on the released py-1.4.14
which fixes py.io.dupfile to work with files with no
mode. Thanks Jason R. Coombs.
- fix junitxml generation when test output contains control characters,
addressing issue267, thanks Jaap Broekhuizen
- fix issue338: honor --tb style for setup/teardown errors as well. Thanks Maho.
- fix issue307 - use yaml.safe_load in example, thanks Mark Eichin.
- better parametrize error messages, thanks Brianna Laugher
- pytest_terminal_summary(terminalreporter) hooks can now use
".section(title)" and ".line(msg)" methods to print extra
information at the end of a test run.
2.3.5 (2013-04-30)
==================
- fix issue169: respect --tb=style with setup/teardown errors as well.
- never consider a fixture function for test function collection
- allow re-running of test items / helps to fix pytest-reruntests plugin
and also help to keep less fixture/resource references alive
- put captured stdout/stderr into junitxml output even for passing tests
(thanks Adam Goucher)
- Issue 265 - integrate nose setup/teardown with setupstate
so it doesn't try to teardown if it did not setup
- issue 271 - don't write junitxml on slave nodes
- Issue 274 - don't try to show full doctest example
when doctest does not know the example location
- issue 280 - disable assertion rewriting on buggy CPython 2.6.0
- inject "getfixture()" helper to retrieve fixtures from doctests,
thanks Andreas Zeidler
- issue 259 - when assertion rewriting, be consistent with the default
source encoding of ASCII on Python 2
- issue 251 - report a skip instead of ignoring classes with init
- issue250 unicode/str mixes in parametrization names and values now works
- issue257, assertion-triggered compilation of source ending in a
comment line doesn't blow up in python2.5 (fixed through py>=1.4.13.dev6)

work with python3.3 (importer ordering)
- issue171 - in assertion rewriting, show the repr of some
global variables
- fix option help for "-k"
- move long description of distribution into README.rst
