CSS test suites

Dave Hyatt writes about the need for browser makers to cooperate with the CSS Working Group to develop comprehensive test suites so that web designers won't have to. Unfortunately, all the test suites I've seen for CSS focus very much on whether the browser handles valid CSS correctly. Just as important is whether the browser handles invalid css correctly. I've seen people complain that it's much harder to test invalid CSS handling since there are so many ways to be invalid. Yes. That's true. Which is all the more reason to do it—testing valid CSS is easy enough that groups other than the W3C can do it if need be; testing invalid CSS is too hard for anyone else to even contemplate bothering.
