Android tap action fails silently

[maartenschumacher]

Description

I'm trying to get my tests running on android, getting stuck on an issue where a tap doesn't have an effect on the emulator, making the next expectation fail. What's strange is that I can't reproduce the issue when I only run the affected test suite (with mocha describe.only). The bug only happens when I run all the test suites. I reload RN between each suite.

Since the unresponsive element triggers a navigation transition, I thought the issue might be the synchronization not waiting long enough, but disabling it doesn't help. Only thing that worked so far is extending the whileElement api with a tap action, so that I can keep tapping the button until the next screen is visible.

So my questions are

1. Would you accept adding tap on whileElement?
2. How can I debug it to get a better understanding of why the tap silently fails?

Steps to Reproduce

Since I can only reproduce the bug as part of a bigger test suite making a demo project would be very difficult.
