Status: RESOLVED FIXED

(Testing :: Mochitest, defect)

Description

[Ryan VanderMeulen [:RyanVM]]

This is showing up in all mochitest-4 runs, but is apparently non-fatal. Appears to have started when bug 1049999 landed (visible in the Try run too).

Ugh, yeah, I see it :(
Ahmed, why did this TEST-UNEXPECTED-FAIL not cause tbpl to go orange? That was the purpose of bug 1049999.

I can see why the test is causing this, it should be easy fixable.

Never mind, I understand. Tbpl is relying on the summary to turn orange.
In this case, the summary didn't count this orange, because we're dumping TEST-UNEXPECTED-FAIL directly out, without updating TestRunner UI. But we can't, because we can't access the TestRunner parent window when this happens, because that is what this bug is about.

Perhaps, I misunderstood SimpleTest.js's philosophy and should it never, even when it tries to access a parent Window when it would cause an uncaught exception.

Probably better to just fix the test.

I've filed bug 1051775 for making this turn the run orange; let's use this bug just for the test_bug789713.html fix :-)

This can all just go into the declarative part now:

<iframe src="file_empty" onload="go()"></iframe>

Make sure to move the <iframe> under the <script> tag when you do that.

You can also remove go() now, right?
