We always need help to produce tests for W3C Recommendations. The more tests we have, the better we'll improve interoperability among Web browsers. Your top features will be better deployed across various Web browsers if you help and we will also improve our HTML5 Test Suite Conformance Results as well.

The HTML testing effort is active on <public-html-testsuite@w3.org> (publicly archive).

We need to improve:

the total number of tests (see How to Write and Submit a Test Case)
the coverage of the HTML5 features (see Existing HTML5 tests)
the classification per feature of those tests
the testing harness, to produce as many automatic tests as possible
