Disabled the test in: https://github.com/mozilla-b2g/gaia/commit/3dd699ab8fb85f70ea3472d9fbc1a2522f78e580

This is an interesting one; it is failing in the setUp before it even gets to the test.

It's possible the previous test is leaving b2g in a bad state.

Comment 3

[[:AndreiH]]

I cannot reproduce this, I run all the tests from system on desktop repeating over 30 times, since Zac suggested that it's possible for a previous test to leave b2g in a bad state.
I don't really know if my methods were correct in investigating this. Do you have other suggestions on how to try to replicate this?

Comment 4

[Kevin Grandon :kgrandon]

I saw this on Travis only twice in ~200 runs. I believe it was the only failure each time. Unfortunately I don't have much more information than that.

Comment 5

[Florin Strugariu [:Bebe]]

Ran this a bunch of times locally and it works... Let's see what Travis thinks 


REPEAT 25

test_app_launched_by_system_message (test_system_message.TestSystemMessages) ... ok

OK

Comment 6

[Florin Strugariu [:Bebe]]

Let's enable this and see how it goes...

Comment 7

[Zac C (:zac)]

Bebe, before you re-enable this can you do a Travis run that repeats the test 200 times?

I think this bug might be improved by bug 956780.

Landed in https://github.com/mozilla-b2g/gaia/commit/4eb1a3ba2b825e210a25f14faacc11c7a7f4e861. If it pops up as an intermittent again we'll have to take another look.
