device/element not found

[nadzic]

Description

When I try to run detox tests element / device is not found. It works with example project from detox repo (demo-react-native-jest).

Steps to Reproduce

I run test with folllowing command: detox build --configuration ios.sim.debug && detox test --configuration ios.sim.debug

What I tried already: downgrade detox, downgrade node, different react native version (0.51, 0.52...), but still getting the same issue. Mazybe there should be some dependecy which causes it?

This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with --detectOpenHandles to troubleshoot this issue.

(this is log from version 7.3.5 detox (because I tried with different versions of detox, but no luck)).

Issue solved, for me the problem was I had loader on splash screen (beat moving loader), and if I did not hide/disable loader, when I went to next screen (react-navigation) then the detox returned this erros. Immediately after I replaced loader with for example Loading... it started working.

I hope it helps!

In my case, this was an async issue. I solved it after doing some digging in Jest's docs (https://jestjs.io/docs/en/tutorial-async). Once I added babel-preset-env and the .babelrc file, the tests ran without any issues
