I cannot push code to the repository, because git hooks in this project is stuck. So I decided to check the tests manually.

When running end-to-end tests of this NestJS application I noticed the following warnings:

Jest did not exit one second after the test run has completed.

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

I think some process is opened in background avoiding to tests to finish.
