There is an "ended" event that would conflict with the "ENDED" constant!

Also, consider "EVENT_RECEIVED-e.type.toUpperCase()".

Indeed there is, but tests are explicitly relying on that. And also note that
adding a prefix without changing the constant makes no difference, since
titlewatcher doesn't require the string to be at the start.

In general, this CL assumes that installTitleEventHandler() is intended to end
the test, but any call to failTest() should not cause the test to succeed. Hence
the case difference between those two paths.

[ddorwin, 2016/03/04 20:14:06]

Hmm. Maybe all the expected strings should have spaces or something (e.g. "E N D
E D"). We can write a JS function to do that here.
Ah, I originally thought "ENDED" was tests complete, but we're actually looking
for playback to have ended.

Acknowledged.
