1043016 - Get mochitests in Gaia OOP mode running on Mulet

Status: RESOLVED WONTFIX

(Testing :: Mochitest, defect)

Description

[Jonathan Griffin (:jgriffin)]

Our current mochitests on Mulet are run in-process, just like desktop Firefox.  We also want to run them out-of-process, in a Gaia app, just like we do for b2gdesktop.

This almost works right now, but the tests still run in the main screen after generating this error:

JavascriptException: JavascriptException: TypeError: homescreen is null
stacktrace:
	execute_script @runtestsb2g.py, line 290
	inline javascript, line 22
	src: "let container = homescreen.contentWindow.document.getElementById('test-container');"

I think it's likely a timing issue.

That seems to be running ?

What's currently running is the same as mochitest on (non-e10s) desktop Firefox.  What used to be running on b2gdesktop was mochitest inside a Gaia OOP test container app.  I'm not sure whether that's still needed or not.

This is already set to false when --oop at https://dxr.mozilla.org/mozilla-central/source/b2g/components/OopCommandLine.js#42; is this still needed?
