Steps to Reproduce

(Write your steps here:)

1. npm test

Expected Behavior

Expected to run App.test.js . and give appropriate results.

Actual Behavior

node[1714] (FSEvents.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-22)
Getting this error. I haven't added any libraries yet. This is the first time I'm trying out testing and have been blocked in the first stage itself. Not able to figure out what the issue actually means.

Reproducible Demo

(Paste the link to an example project and exact instructions to reproduce the issue.)

Would also like to mention that there is another create-react-app project with a higher version

npmPackages:
   react: ^16.5.2
   react-dom: ^16.5.2
   react-scripts: 2.0.3

in my system. But npm test is working fine as expected. So I believe this is not a system specific issue as the environments for both projects are same.

Try brew install watchman?

Try brew install watchman?

Does anyone know why watchman is suddenly required?

[heyimalex]

@tim-rohrer I think this is the relevant issue, or maybe the jest issue it links to.

As I understand things, and am experiencing on my system, this is the more relevant issue. However, in my situation, I'm not on Sierra nor have I been for years. But, installing watchman seems to have solved the issue. That is good.

But, it still isn't clear to me what is actually requiring watchman?

[heyimalex]

I think jest uses watchman when it's globally installed.
