java.lang.RuntimeException: androidx.test.services.shellexecutor.ClientNotConnected

See original GitHub issue

Description

Instrumentation test randomly failing. When running espresso tests on our CI machine (which runs tests on Firebase Test Lab) we occasionally get the following crash and then the tests stop:

It’s never the same test causing the problem. Not sure it matters but it’s only when testing on Nexus5X emulator for API versions 23 / 24. Tests on other emulators / API versions all pass fine.

Steps to Reproduce

none

Expected Results

Tests should continue and complete

We also have this issue but we always had clearPackageData enabled like mentioned by @tobrun I’m not sure if that’s the cause.

Is there anything we can do to help proceed investigation of this issue?

@athkalia this started happening on all of our test emulators (including API28). I think what was happening was that we were hitting the default 15 min timeout for Firebase Test Lab. Depending on how you trigger your tests you may need to increase the timeout

When we bumped to 30 mins, everything was fine.
