James can you please assign someone to take a look?

Comment 12

[James Teh [:Jamie]]

Looks like yet another instance of bug 1708336. We still don't have any clue what's going on there. :(

Morgan, would you mind describing the screenshot here in contrast to the other screenshots related to bug 1708336? is this another "blank page" case?

Comment 13

[Morgan Reschenberg [:morgan]]

Sure thing :)

All the screenshots in the most recent logset are the same: There are two tabs "New Tab" which is in the background, and "Accessibility Test" which is in the foreground. The web area of the foreground contains the text "one". The URL bar contains (presumably) the test URI and is shaded red

Comment 14

[James Teh [:Jamie]]

So the document is loading in this case and we're just not getting any a11y events for it. 😩

I looked into enabling a11y engine logging for this test, but that's going to be more complicated than I anticipated. Calling enableLogging (or accService.setLogging) only enables it for the current process, which in this case will be the parent process. We need it for the content process. Unfortunately, we can't get the remote browser until after we've loaded the page, which is too late; we need content process logging to start before that.

Comment 15

[James Teh [:Jamie]]

Attachment: Bug 1636476: Enable a11y logging for accessible/tests/browser/events.

I can't reproduce this on try, so I'm landing this so I can get (hopefully) useful info next time it fails.

Comment 18

[James Teh [:Jamie]]

Despite A11YLOG being enabled (and the log shows that the environment variable got set), I don't see any a11y logging in the log. I guess the CI logs don't capture stdout or something? I don't understand how I'm supposed to get the logging I need to figure this out.
