805801 - [B2G] Marionette problem causing the test to fail

Status: RESOLVED INVALID

(Remote Protocol :: Marionette, defect)

Description

[Zac C (:zac)]

This test started failing on yesterday's build with a marionette problem. The session does not seem to be able to recover after this point and following tests fails.

I haven't been able to debug it any further, sorry.

Here's a stack trace excluding the teardown:

Comment 1

[Jonathan Griffin (:jgriffin)]

This error could occur because the target app (Camera, in this case) has crashed.  Can you verify that's not the case?

Comment 2

[Zac C (:zac)]

Yes I think you're right, it's crashing manually for me.

This affects the CI run because the tests that run afterwards fail with the same error.

Can we change the tearDown somehow to cope with this and recover for future tests?

Comment 4

[Jonathan Griffin (:jgriffin)]

I can't reproduce this problem, but this test no longer causes the camera app to crash.  I think this is possibly still a problem, but don't know how to reproduce.  Are there any tests that currently cause app crashes reliably?

Comment 5

[Zac C (:zac)]

I haven't seen this failure lately but as we're only really testing 3-4 apps at the moment.

Comment 6

[Stephen Donner [:stephend] Not actively reading bugmail]

Zac, can we close this?  Any new/current information which would have us leave this open?

Comment 7

[Zac C (:zac)]

Closing, haven't seen this error for a long time.
