"npm test" with "--coverage" argument doesn't make the script fail even if the threshold is not met

[trish123]

1. Create an app with CRA

2. Add the coverage threshold in the package.json file
   "coverageThreshold": {
   "global": {
   "branches": 90,
   "functions": 90,
   "lines": 90,
   "statements": 90
   }
   }

3. run the command - npm test -- --watchAll=false --coverage

4. We can see "index.tsx" is not covered and the "threshold not met" messages in the console. But the script is not failing.

Does CI=true work for you?

Does CI=true work for you?

Yes. It works in CI server. If i set the env (CI) variable, it works in local system as well. I am running this as part of precommit hook. Is it recommended to set CI variable? Or is it a workaround?

I am not sure why there is a difference. I think this is a jest bug.
