1048080 - B2G debug mochitest-6 failure with only "Return code: 1" present in the brief log

Status: RESOLVED DUPLICATE of bug 1048288

(Testing :: Mochitest, defect)

Description

[JW Wang [:jwwang] [:jw_wang]]

I was trying to enable content/media/test/* on B2G emulator debug and found the errors below.

https://tbpl.mozilla.org/?tree=Try&rev=4777f5af2ba7
https://tbpl.mozilla.org/php/getParsedLog.php?id=45127729&tree=Try&full=1

It looks like a shutdown error while running the command |ps -C emulator|
10:44:37     INFO - Return code: 0
10:44:37     INFO - Running command: ['ps', '-C', 'emulator']
10:44:37     INFO - Copy/paste: ps -C emulator
10:44:37     INFO -    PID TTY          TIME CMD
10:44:37    ERROR - Return code: 1

I think there is a problem with reporting of test failures on emulator test runs.  If you search in the full log for "Assertion count 1 is greater" you can see that content/media/test/test_playback.html failed with one unexpected exception.

Thanks for the clarification. I will look into test_playback.html to find out what goes wrong.

This sounds like bug 1048288 (regression from mochitest structured logging).
