Test Butler unable to dismiss QuickStep ANR's in Detox 19.5.7

What happened?

After updating to Detox 19.5.7 from Detox 19.4.5 Test Butler has been unable to dismiss QuickStep ANR Modals.

Screenshot

What was the expected behaviour?

QuickStep ANR system modal dismissed by Test Butler.

Was it tested on latest Detox?

• I have tested this issue on the latest Detox release and it still reproduces.

Did your test throw out a timeout?

• I have followed the instructions under Identifying which synchronization mechanism causes us to wait too much.

Help us reproduce this issue!

Will work on creating reproduction of this issue with the DetoxTemplate this upcoming week.

In what environment did this happen?

Detox version: 19.5.7 React Native version: 0.66.4 Node version: v12.22.0 Device model: Android SDK built for x86_64 Android version: 10 Test-runner (select one): jest-circus

Detox logs

Detox Logs from CI are too long to attach - will include once able to reproduce in DetoxTemplate.

Device logs

More data, please!

Will attempt to downgrade Detox 19.5.7 --> Detox 19.5.1 --> Detox 19.4.5.

Well there are a few things that come to mind:

1. It is possible that while you have test-butler installed, it’s service isn’t running. Dive deeper into the the section on test-butler in the blogpost to see what’s missing.
2. Since it’s Quickstep that isn’t responding (the device’s launcher) and not the app itself, it is fairly possible that the emulator is a bit slow during boot-time, and hence this happens regardless of Detox or your app. In such cases, the best practice is to have test-butler preinstalled and running on your emulator’s quick-boot image.

Beautiful, thank you!
