A flaky clock-app autopilot test test_add_recurring_type_alarm_must_add_to_alarm_list(weekday)

[Timo Jyrinki]

The test_add_recurring_type_alarm_must_add_to_alarm_list(weekday) test is flaky as on the image #294 tests a re-run was needed before the test passed. On the flaky run it ended with "ubuntuuitoolkit.emulators.ToolkitEmulatorException: The tab with index 1 was not selected."

I'm attaching a log snippet from the failing run. It may be however hard to reproduce since I've not been able to reproduce it locally.

Have you seen this before or was it a one-off? Adding Leo to see if this is simply a tab switching thing with the emulator.

[Timo Jyrinki (timo-jyrinki)]

So far this seems one off.

[Leo Arias (elopio)]

This exception was one we added to avoid an infinite loop while switching tabs. It means that the switch is not working, but without a video of what's going on it's really hard to tell the reason.

From the logs:
06:34:30.655 DEBUG emulators:155 - Switch to tab with index 1.
06:34:31.004 DEBUG emulators:164 - Current tab index: 0.
06:34:31.007 DEBUG emulators:140 - Switch to next tab.
06:34:32.331 DEBUG emulators:164 - Current tab index: 0.
06:34:32.333 DEBUG emulators:140 - Switch to next tab.
06:34:33.896 DEBUG emulators:164 - Current tab index: 0.
06:34:33.898 DEBUG emulators:140 - Switch to next tab.
06:34:35.249 DEBUG emulators:164 - Current tab index: 0.

It could be that the header is unresponsive, or that autopilot is not clicking on the right place.

This is still an odd error to see, but the simplest explanation is a UI freeze, not something within the test or sdk helper.

As to why the UI would sometimes lock, since this is adding alarms, I would have to ask Nekhelesh if having a worker thread for adding an alarm would affect the UI or not. I will say I have seen this as a one-off before in other apps.

[Nekhelesh Ramananthan (nik90)]

Well the saving of the alarms is already done asynchronously by the SDK. So I don't think there is much that I can do here. Let me talk to zsombor and see if the situation can be improved.
