Add sync/async test types for generated canvas tests Generated canvas WPT tests use a custom `_addTest` helper method. This helper offers a domain-specific API (only supported for canvas tests) that can be used to "easily" implementing either synchronous or asynchronous canvas tests. This helper however strays away from standard testharness.js test format, making it impossible to use many features that are otherwise standard in WPT. For instance, it used to be impossible to test using promises. We had to modify the test generator to bypass the `_addTest` helper so we could use the standard `promise_test` feature. Using a custom domain specific API also makes it harder to move between canvas and non-canvas folders, making maintenance and collaboration more difficult. In a follow-up CL, we will add support for generating canvas tests packing multiple test cases in the same file. This is commonly done in WPT, where we would put in the same file multiple test/async_test/ promise_test that are all related with each other. This cannot be done with `_addTest` however because that function expects the DOM to have a single unique canvas element to be used by the test, making it impossible to have multiple test cases in the same file. This CL adds support for using the standard `test` and `async_test` API, specified via the `test_type` YAML parameter. If `test_type` is unspecified, the default `_addTest` API is used.

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.

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!
