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 which 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.
The most important sources of information and activity are:
github.com/web-platform-tests/wpt: the canonical location of the project’s source code revision history and the discussion forum for changes to the code
web-platform-tests.org: the documentation website; details how to set up the project, how to write tests, how to give and receive peer review, how to serve as an administrator, and more
wpt.live: a public deployment of the test suite, allowing anyone to run the tests by visiting from an Internet-enabled browser of their choice
wpt.fyi: an archive of test results collected from an array of web browsers on a regular basis
Mailing list: a public and low-traffic discussion list
If you’d like clarification about anything, don’t hesitate to ask in the chat room or on the mailing list.
