Detox step into infinite wait with message "the app seems to be idle"

[aaronpliu]

What happened?

In a normal test scenario, when an unexpected popup appear or element not found, the detox will loop to print "The app seems to be idle" instead of throwing error or stop. It never exit or continue after a long long time

What was the expected behaviour?

either exit execution or throw error if no condition meet (e.g. element not visible or exist or unexpected dialog)

Was it tested on latest Detox?

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

Did your test throw out a timeout?

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

Help us reproduce this issue!

@d4vidi , @gosha212 would you please take a look at it? no more detailed log to double check, it encountered this error in some test scenarios. for instance, unexpected popup appear, element not found, or page auto refresh...etc.

Thanks in advance

the behavior seriously impact test scripts running and block test. Especially when the internet speed is not fast. It should be fail fast rather than infinite wait and stuck. I really appreciate your investigation and any workaround to settle.

I have similar problem I use: "detox": "20.17.0", "react-native": "^0.72.10" This is the error that I am seeing: Test Failed: Wait for [LooperIdlingResource-138-mqt_js] to become idle timed out

Experiencing the issue all the time :-(

@aaronpliu @KaterinaUK Can you share a sample project please? How often is it reproduces (Always / Sometime)?

Hi @gosha212 , Unfortunately, I do not have a sample project, it is a private project that I am working on right now. I have it every day, this is the error I can see: Test Failed: Wait for [LooperIdlingResource-101-mqt_js] to become idle timed out at Object.withTimeout (/Users/runner/work/app/app/e2e/new-user.test.js:26:8) at Generator.next (<anonymous>) at asyncGeneratorStep (/Users/runner/work/app/app/node_modules/@babel/runtime/helpers/asyncToGenerator.js:3:24) at _next (/Users/runner/work/app/app/node_modules/@babel/runtime/helpers/asyncToGenerator.js:22:9) at processTicksAndRejections (node:internal/process/task_queues:95:5)
