If you are reporting a bug, please fill in below. Otherwise feel free to remove this template entirely.

Can you reproduce the problem with latest npm?

Yes, I'm on yarn 0.21.3

Description

yarn test gives me "Your test suite must contain at least one test." even though I have a test.

Expected behavior

yarn test should show me 1 test succeeded.

Actual behavior

 FAIL  tests/all.test.js
  ● Test suite failed to run

    Your test suite must contain at least one test.

It's just vanilla create-react-app-ts and then that single test added. Run yarn test in that app to repro.

hey, have you got any updates on this issue?

Hm sorry missed this. It seems to work now for my. I suspect maybe a different global typescript version or something like that. I'll close for now
