Also

Same happening on Ubuntu (unable to tell exact version)

Steps to Reproduce

npx create-react-app test
cd test
yarn test

Expected Behavior

Since I don't have any non staged changes jest should resolve (and run) all the tests.

Actual Behavior

outputs:

$ yarn test
yarn run v1.15.2
$ react-scripts test
No tests found related to files changed since last commit.

and the process hangs (doesn't exits)

on our Jenkins it ran more than an hour
