NPM ERR! Test failed - Not able to run test

Running a few tests for react js using Jest and Enzyme but one of the files keeps breaking. Using Jest and Enzyme

I already cleared the cache, but I keep getting the following :

NPM ERR ! Test failed
and worker process has quit unexpectedly!

Most likely this is an initialization error
Here is part of the package.json. Not really sure how to fix this problem.

Delete node_modules and package-lock.json or yarn.lock files. Run npm install again and see if that fixes the issue.
