part 2: When computing static position of abspos grid child, perform alignment within content-box, rather than padding box. In the conditions where we hit this partiuclar codepath, the spec used to require us to align within the grid's padding box (which is what we were trying to do[1]), but now it requires us to align within the grid's content box. This patch makes us start passing a bunch of WPT tests (whose .ini files I'm removing here). This patch also changes the reference case for some "last-baseline"-specific tests in the same directory, by cribbing the "alignEnd" rule from the neighboring non-"last-baseline" analog (since "last-baseline" falls back to end alignment and is meant to be equivalent in these testcases). Before this patch, the affected reference cases were inadvertently depending on the Firefox bug that I'm fixing here, and they were expecting the testcase's end-aligned content to be at the wrong position as a result. Chromium developers fixed this issue in the neighboring non-"last-baseline" tests in [2], but they didn't catch the files that I'm fixing here, because Chromium doesn't implement "last baseline" alignment yet. [1] Before this patch, we actually weren't quite aligning within the padding-box, even though we were trying to. We were computing an alignment offset based on the size of the padding box, and then we were using that offset as a position within the *content box*. This could result in us pushing end-aligned content outside the grid entirely, as in the testcase on the bug report for this bug.

The web-platform-tests Project is a cross-browser test suite for the Web-platform stack. Writing tests in a way that allows them to be run in all browsers gives browser projects confidence that they are shipping software that is compatible with other implementations, and that later implementations will be compatible with their implementations. This in turn gives Web authors/developers confidence that they can actually rely on the Web platform to deliver on the promise of working across browsers and devices without needing extra layers of abstraction to paper over the gaps left by specification editors and implementors.

matrix channel; includes participants located around the world, but busiest during the European working day.If you'd like clarification about anything, don't hesitate to ask in the chat room or on the mailing list.

Note: because of the frequent creation and deletion of branches in this repo, it is recommended to “prune” stale branches when fetching updates, i.e. use git pull --prune
(or git fetch -p && git merge
).
See the documentation website and in particular the system setup for running tests locally.
The wpt
command provides a frontend to a variety of tools for working with and running web-platform-tests. Some of the most useful commands are:
wpt serve
- For starting the wpt http serverwpt run
- For running tests in a browserwpt lint
- For running the lint against all testswpt manifest
- For updating or generating a MANIFEST.json
test manifestwpt install
- For installing the latest release of a browser or webdriver server on the local machine.wpt serve-wave
- For starting the wpt http server and the WAVE test runner. For more details on how to use the WAVE test runner see the documentation.On Windows wpt
commands must be prefixed with python
or the path to the python binary (if python
is not in your %PATH%
).
python wpt [command]
Alternatively, you may also use Bash on Ubuntu on Windows in the Windows 10 Anniversary Update build, then access your windows partition from there to launch wpt
commands.
Please make sure git and your text editor do not automatically convert line endings, as it will cause lint errors. For git, please set git config core.autocrlf false
in your working tree.
The master branch is automatically synced to wpt.live and w3c-test.org.
Save the Web, Write Some Tests!
Absolutely everyone is welcome to contribute to test development. No test is too small or too simple, especially if it corresponds to something for which you've noted an interoperability bug in a browser.
The way to contribute is just as usual:
git checkout -b topic
../wpt lint
as described above.If you spot an issue with a test and are not comfortable providing a pull request per above to fix it, please file a new issue. Thank you!
