Welcome to the HTML5 test suite, a work in progress. You can:
- Review very early test results for some browsers. The results are not significant given the small number of tests. It is a work in progress.
- Run the tests yourself. The test results only cover test cases approved by the test suite task force (a subset of all the tests available).
- Get involved! The HTML5 implementations of tomorrow are being developed and tested today and we welcome your contributions.
