Status: NEW → RESOLVED
Closed: 4 years ago
Resolution: --- → INCOMPLETE

Recent failure log : https://treeherder.mozilla.org/logviewer?job_id=325231143&repo=mozilla-central&lineNumber=3782

Status: RESOLVED → REOPENED
Resolution: INCOMPLETE → ---

The failure seems to indicate some activity in the inspector, I guess since we're opening the toolbox without specified tool.
The test has some old style (no add_task, chained Promises) and is quite hard to follow + it sets prefs it never reverts.
I'm going to refactor the test and remove the annotation that were added to it.

Status: REOPENED → ASSIGNED

We migrate the test to add_task and async functions and
properly set preferences at the beginning of the test.
