npm test hangs for newly generated app

See original GitHub issue

Can you reproduce the problem with latest npm?

Yes.

Description

A newly generated app hangs indefinitely on npm test.

Expected behavior

The App.test.js file test should run.

Actual behavior

The test process hangs.

Environment

Run these commands in the project folder and fill in their results:

npm ls react-scripts (if you haven’t ejected): playground@0.1.0 /Users/stephen/Developer/playground └── react-scripts@0.7.0
node -v: v6.9.1
npm -v: 3.10.9

Then, specify:

Operating system: macOS Sierra 10.12.1 (16B2555)
Browser and version: n/a

Reproducible Demo

If need be I can attach a demo, though I assume I would need to recursively remove the .gitignores and commit the modules?

Steps to reproduce for me every time:

create-react-app playground
cd playground
npm test

Just chiming in for anyone running into this problem, I ran into this same issue. Uninstalling watchman fixed the problem, though installing watchman again reintroduced the problem. The underlying problem (for me atleast) is detailed in https://github.com/facebook/watchman/issues/358 and is related to corrupted state.

tl;dr try running launchctl unload ~/Library/LaunchAgents/com.github.facebook.watchman.plist, which should hopefully fix running tests (npm test) with watchman installed!

brew uninstall watchman did the trick. Should I file a bug there?
