Testing

Our conformance test suites: how to run them, known bugs, and how to contribute.

[!NOTE] The tests are maintained in the web-platform-tests Git repository, mostly in the css subdirectory.

Test suite and test case discussion takes place primarily in GitHub issues, with policy matters occasionally discussed on the public-test-infra mailing list. The #testing channel on irc.w3.org:6665 is also available for discussion, and is recommended for anything where a quick response is desirable.

If this is your first time working with Web Platform Test, see this introduction and tutorial:
