889939 - Intermittent Robocop testJarReader |Automation Error: No crash directory (/mnt/sdcard/tests/profile/minidumps/) found on remote device

Status: RESOLVED FIXED

(Firefox for Android Graveyard :: General, defect)

Description

[Geoff Brown [:gbrown]]

Many of the recent failures in bug 722166 happen during testJarReader, which was recently re-enabled.

It appears that the test completes normally, but the minidumps directory is simply not created.

This is likely our fastest/shortest running test, completing in about 1 second. I wonder if simply waiting at the end of the test for Gecko:Ready (or something else?) would sort this out.

Gecko:Ready would work, assuming that minidumps is created before Gecko:Ready.  This is kind of madness, though: we'll trade success followed by not finding minidumps for intermittent failures when Gecko:Ready doesn't arrive.

Attachment: wait at end of testJarReader for Gecko:Ready

Waiting for Gecko:Ready seems to be effective:

This sometimes adds up to 4 seconds to the run time, but I think that's reasonable.

Technically I'm not a Fennec peer, but this is trivial and should help immediately.
