After updating to Compose 1.2 we have a ton of flaky UI tests (end-to-end tests).
• Test instrumentation process crashed. app simply stops responding to some focus event and then instrumentation timeouts after 5 seconds, what's more, the interaction is on non-compose view at this particular time.
• java.lang.IllegalStateException: No compose hierarchies found in the app. Possible reasons include ... suddenly this started happening, but not always - probably tests access activity too early, seems like idling resource issue, but this was not happening at all before update
• Compose recomposing forever - timeouting because not able to reach an idle state - this was only issue I was able to fix - we were missing remember , but actually without UI test no repeated recomposition was happening there
Do you any similar experience, tips where to look for issues/errors/fixes?

@Jan Skrasek
Did you ever find a workaround for this?

[Jan Skrasek]

Just yesterday we have updated to Compose 1.3 which seems to fix (🙏) the Test instrumentation process crashed.

The No compose hierarchies found in the app. seems to be fixed (don't know why) by this particular change I did yesterday:
• we were using createEmptyComposeRule for our full end-to-end UI tests that were using own ActivityAscenarioRule.
• I've replaced createEmptyComposeRule with this:

@get:Rule
  val composeTestRule = AndroidComposeTestRule(activityTestRule) {
    error("Can't provide current activity")

The activityTestRule is the activity scenario rule we had there for the whole time.

Thanks. I managed to reproduce it after a few iterations, dump linked int he ticket

If you have any code/minimal repro I think they could utilize it for the fix.
