Peter Linss asked for help of one of the admins of our mercurial testing repo. He would like to help setting it up. Can you talk with Peter Linss, Cameron?

It absolutely depends. At the end they will live as HTML tests in the CSS test suite and as SVG tests in the SVG test suite I guess.

A great idea!

I am not so sure if we should ask for tests for the SVG test suite. We definitely have Transforms as topic for this event. And Transforms for SVG is definitely part of this topic. But I would like to write the SVG tests with inline SVG in HTML and use Tav's script to convert all these tests to pure SVG tests afterwards. Actually most of the >600 tests for CSS3 Transforms are testing the behavior for SVG already.

No, I assume it is the same problem like for editing the spec. The lack of time. Hopefully not a lack of interests, since testing is extremely important. That was/is one of the biggest issues of the current test suite. We don't have enough tests, we don't have enough detailed tests and we don't have tests that can easily be run automatically by any UA.
