1113422 - unexpected test failure: "uncaught promise rejection" in bare addon

Status: RESOLVED WORKSFORME

(Add-on SDK Graveyard :: General, defect)

Description

[Cooper Quintin]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/39.0.2171.65 Chrome/39.0.2171.65 Safari/537.36

Steps to reproduce:

I created a new browser extension by running the command "cfx init myext". I then changed to the `myext` directory and ran the tests, getting a failure.  Running addon SDK version 1.17 on linux. 


Actual results:

The tests failed with the following error:
```

2 of 3 tests passed.
```



Expected results:

The tests should have all passed, since this is a brand new extension created from the addon sdk with no custom tests. 

Interestingly, when running the tests against firefox 35 I get the expected results:
```
Running tests on Firefox 35.0/Gecko 35.0 ({ec8030f7-c20a-464f-9b0e-13a3a9e97384}) under linux/x86_64.
..
2 of 2 tests passed.
```

This makes me think that perhaps the bug could be related to this fix: https://bugzilla.mozilla.org/show_bug.cgi?id=1072118

which should probably be backported into the 34 branch.

34 branch is almost EOL, FF35 will be released in January.

Comment 2

Marking this as WFM because it's fixed post-34 -- 35 will be released this week.
