Jest "No tests found, exiting with code 1" error on Windows 10 in React Redux application

I am a bloody idiot and I didn't pay attention to the details.

Jest is looking for test.js specifically. Not testS.js. My files were labeled as tests.js. It worked inside __tests__/ because Jest just looks for anything inside there.

I got it working just fine now, and it shall remain up as a testament to me not looking at the specifics of the regex matches.

From my side, I was getting this error because I had placed myself (cd) in the directory where the chromeDriver was installed, so as not to have to add its path to $Path. After I added chromeDriver to $Path, and placed myself in the directory of my project, everything went fine.
