Patrick,

Thanks, that was one of the items on my test list to include. I am using Inspect and accessibility probe as I find Aview does not work well with screen readers. I also found the ARIA Git pattern from w3c which could be a starting point.

One step necessary to check if something's a browser or AT issue is to use a tool that shows you what the browser is actually exposing via the accessibility API. On Windows for instance, you could use things like Inspect
https://msdn.microsoft.com/en-us/library/windows/desktop/dd318521%28v=vs.85%29.aspx?f%5&MSPPError=-2147217396
or aViewer https://developer.paciellogroup.com/resources/aviewer/
(disclosure: I work for TPG)

This gives you an insight into whether or not a browser is exposing stuff correctly or not. When just testing browser+AT combinations, one of the problems is that you'll get AT also using heuristics and error-correcting if browsers aren't exposing the correct stuff, so it won't help you easily identify if a discrepancy of how one AT works with a browser compared to another AT is a sign of the AT having issues, or if it's the browser not exposing correct stuff and then ATs simply having different heuristics to cope with that situation.
