Investigate catching uncaught JS exceptions through window
.onerror in iframes (or child windows) of (plain) mochitests
This is a follow-up to bug 652494 and bug 703176. 1- Mark (various) noticed cases as dependent. 2- Try to investigate and find a solution if possible.
Summary: Some plain mochitests still not failing when uncaught JS exceptions occur → Investigate catching uncaught JS exceptions through window.onerror in iframes of plain mochitests
Iirc, I initially filed this bug for plain mochitests only as a first step: the assumption was +/- that plain tests should "never" cause exceptions, whereas we might need to deal with "expected" exceptions in some (browser-)chrome tests. Anyway, the first part should be to at least catch and report these/all exceptions as warnings. Then we can decide how to proceed from there.
Ftr, targeted exceptions are ones that show up in the Error Console (as uncaught), but that our SimpleTest harness doesn't currently see/catch.
Component: BrowserTest → Mochitest
