Hi, I realise we haven't formally adopted any tests yet (so please reply to the call for consensus[0]). On the other hand, we have a bunch of results[1] for the proposed tests[2]. On the browser + screen reader side, the results look reasonable. If anyone has IE 11 it would be interesting to see if they have fixed the apparent bugs they have, but it looks clear that longdesc can be implemented interoperably even for corner cases. I'd like to split the results to distinguish between reasonably simple implementations to use, and things that technically pass but shouldn't be considered evidence of good implementation. E.g. without extensions / assistive tech of some kind Opera 12's access is mostly very good, but discovery is poor, and my bare Firefox 23 can only be said to pass some tests because the spec makes no requirement that the UI be effective enough for the real world - although I believe they have improved that. On exposing longdesc to accessibility APIs things look rather shakier. On the other hand, it is not clear whether the testers were certain what a pass or fail actually was so our results might be unreliable here. It would be helpful to have more testing on APIs, by people who really are clear what is required. Finally, there are a few tests for validators. The basic tests come out right, but the test for the "should" requirement of encapsulating longdesc[3] doesn't get picked up by any tool I know. I've cc'ed Andrew, who wondered if we had requirements on this, to find out if he knows of any tool that would at least warn about the error.
