Thanks for the quick reply. I’ll be sure to check wptrunner out.

I’m also planning to contribute a few tests. I wonder if a spec has to reach certain level before tests can be added to wpt? For example, tests for the ChildNode interface introduced in dom4 seems to be missing from wpt. If I submit tests like these, will they be merged? What happens if specs do introduce breaking changes?

Also, some tests are unlikely to fail in browsers but polyfill libraries might fail them. For example, many classList polyfill libraries treat classList.toggle(“name”, undefined) the same as classList.toggle(“name”). Will wpt be interested in merging tests like these?

@ Andreas

You mean something along the line of quirksmode’s compatibility table and caniuse? That would be very cool, and I think the table provided by wpt can be way more granular, which should be very informative.
