Jest notify option error "Jest did not exit..." and no coverage summary

[timbergus]

🐛 Bug Report

I have updated recently to [email protected] and using my old config file appears the following error:

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.

This error disappears when removing the notify option from the configuration file.

To Reproduce

Install [email protected], create a simple test file true.test.js:

test('True to be true!', () => expect(true).toBe(true));

Create a jest.config.js file and add this content:

module.exports = {
  notify: true,
};

Run Jest from the package.json test script:

{
  "scripts": {
    "test": "jest"
  }
}

Expected behavior

I expect to obtain notification when finished (appers, but long after finished), and a clean output with the coverage summary. Instead, I obtain the error message. And when removing the notification option, I obtain a clean output, but no coverage summary (not sure if the missing summary is related, but both appear at the same time).

This is the output with [email protected], same error, and no coverage summary:

This is the output with [email protected], same error, but with the coverage summary:

This is the output with [email protected], no error and coverage summary (but I needed to add testURL: 'http://localhost/' to the config file to pass the tests):

I am having the same issue as well. I have tried removing & adding the flag & the error only appears when the flag is present.

OK. It seems that the coverage summary is not an error. It has stopped being automatic. Now it's needed to be configured in coverageReporters option.

{
  coverageReporters: ['text-summary'],
}

And for now, the timeout problem can be avoided using jest --detectOpenHandles. This is the result with the new configuration using [email protected].

I still think the issue with --notify is a bug & using --detectOpenHandles would be a band aid solution.

This should be fixed after the change in node-notifier was reverted in 5.4.1. Update your lockfile and you should be good

[sergtimosh]

It reproduces for me with "node-notifier": "^6.0.0"

[SimenB]

Yeah, fixed in #9567

[sergtimosh]

Yeah, fixed in #9567

I've just updated packages, but problem still persists

Fix is not released
