3. Create a new app using create-react-app: create-react-app parens
4. Go into the newly created my-app directory: cd parens
5. Install dependencies: npm install

7. You should see a prompt that says "No tests found related to files changed since last commit."
8. Press "a" at the prompt to run all the tests.

Expected Behavior

The tests in src/app.test.js should be run.

Actual Behavior

A message about no tests being found will be shown.

Reproducible Demo

https://github.com/rimunroe/create-react-app-parens-in-test-path

It looks like the parentheses in the path that make up the <rootDir> later passed to Jest's testMatch option by create-react-app's config are being interpreted by Jest as grouping characters. I've filed this as an issue with Jest jestjs/jest#4838 as well.
