Status: RESOLVED DUPLICATE of bug 915810

(Testing :: Mochitest, defect)

Description

[Jonathan Griffin (:jgriffin)]

When attempting to run B2G mochitests on a real device, there are lots of devicemanager- and mozrunner-related errors, e.g.,

Mochitest INFO | runtestsb2g.py | Running tests: start.
remount succeeded
B2GRunner INFO | waiting for device to come back online after reboot

I suspect mozrunner's remote.py hasn't been tested against real devices.

Duping this bug as there is a WIP patch in the other one. I think the patch there will fix the devicemanager/mozrunner errors, but I still ran into problems after that and never got around to fixing it completely.
