Jest/watchman stalls on "Determining test suites to run..."

bug

Running jest lasts about 5-10 minutes before the test completes, leaving the message:

“Determining test suites to run…”

The issue started occurring after I followed the directions from a warning (note: computer username replaced with USERNAME):

watchman warning:
To clear this warning, run:                                                                                   
`watchman watch-del /Users/USERNAME ; watchman watch-project /Users/USERNAME`

If you run the previous script, Jest calls “watchman” which then appears to do the intensive task of searching for all files located under my username.

I would suggest suppressing the “watchman” warning to avoid giving poor advice to other users.

Is /Users/USERNAME under version control? I’m assuming that you have a .git dir there. Watchman will try to watch at reasonable-looking project roots and if you home dir looks like one then it will use that as the location to watch.

You can avoid this in a couple of ways:

Ensure that you initialize version control in your child project before starting watchman on it (yeah, this sounds a bit weak)
Configure your /etc/watchman.json file to set https://facebook.github.io/watchman/docs/config.html#root_files and https://facebook.github.io/watchman/docs/config.html#enforce_root_files to only allow watching projects that have a .watchmanconfig configuration file. This is what we use inside FB.

I’ve been thinking about adding an restriction against watching home directories in a future release, but haven’t had the bandwidth to do this.
