Im implementing tests framework (jest) in react native with testing-library/react-native, on an existing project. When I run their example (intro) the app give the infamous error:
Jest did not exit one second after the test run has completed.
when I try to check it with the flag --detectOpenHandles, it shows that the library itself is the problem.

I have no config file for jest. RN - 66.4 jest - 28.1.0 babel-jest - 26.6.3 jest-circus - 26.6.3 eslint-plugin-jest - 26.1.1
