In testNext, the function passed to addEventListener closes over the pos variable, but I'm guessing that it could be incremented before the event listener is actually invoked.  You can see right after the TEST-UNEXPECTED-FAIL in comment 0 the "TESTS[pos].onload is not a function" message, so it looks like pos is going wrong.

This patch uses 'let' to capture the value of pos.

Boo.  Let's dump the unexpected error console message to see what it's getting.

I have a hunch what's happening here.

There have been some patches in Web Console which made the code somewhat more flimsy. It spits out errors when it shouldn't.

Those errors intervene in the way the test for bug 595934 works.

The fix should be in other parts of the Web Console, not in the test.

One such example error:

TEST-INFO | chrome://mochitests/content/browser/toolkit/components/console/hudservice/tests/browser/browser_webconsole_view_source.js | Console message: [JavaScript Error: "[Exception... "'JavaScript component does not have a method named: "observe"' when calling method: [nsIObserver::observe]"  nsresult: "0x80570030 (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)"  location: "JS frame :: resource:///modules/HUDService.jsm :: HS_registerHUDReference :: line 1704"  data: no]" {file: "resource:///modules/HUDService.jsm" line: 1704}]


registerHUDReference() holds:

Services.obs.notifyObservers(id, "web-console-created", null);

There must be an observer registered that does not have the "observe" method.

Mihai, is what you're talking about in comment 14 something which could have caused bug 645267 as well?

I highly doubt that, I am 99% sure that comment 14 is unrelated to bug 645267.

However I am quite certain that that comment is sufficiently accurate - I continue to believe this orange is caused by what I said in the aforementioned comment. Someone can track the regression, when the code was added, and why the error occurs. Once we fix that error, I expect we will no longer see intermittent failures in the test discussed in this bug report.

If wanted, I can take the bug.
From the debug log, I'm thinking the problem is that the load event listener is getting called for the previous subtest's document load -- the loop comes around to running subtest #4 (the one with the onload), but this sometimes happens before the document from subtest #3 has finished loading (i.e. the console message gets shown before the document's load event is dispatched).  This would be why the querySelector("form") call is not returning an element.

Patch coming up after a tryserver run.

This makes sense to me.  Relying on the order of load events is a mistake, as we all know.  :-)

Random orange fix for browser_webconsole_bug_595934_message_categories.js; make sure we listen for the right load event.

The patch change is fine, but I am not sure if these changes are sufficient.
