Description

Expected Behavior

Tests should pass or fail in a timely and consistent manner

Current Behavior

This particular test seems to hang sometimes and run properly other times

Possible Solution

These are usually really hard to track down

Context

This happens often when running the full environment unit tests in pcds-envs which kills the suite after 10 minutes.

I tried applying pytest-timeout to this test today but it seems unable to interrupt it. I wanted to apply a 20 second timeout so that the pcds-envs full environment unit test could rerun the test quickly if it was hanging as a band-aid measure but it's not working properly.

Your Environment

pcds-5.5.1

Research direction

Start by running the test_app_buttons test in the full pcds-envs environment and compare runs that complete with runs that hang. Investigate why pytest-timeout cannot interrupt the test, then verify that the test completes or fails consistently without causing the full unit-test suite to exceed its limit.
