How to make Flow aware of Jest's globals (test, expect, etc)?

Question

I get these Flow errors in my test files:

identifier `test`
Could not resolve name

identifier `expect`
Could not resolve name

I've installed the Jest libdef from flow-typed but it doesn't make any difference.

---

Update: it looks like the Jest libdef created by flow-typed is just a stub. I think the problem is that flow-typed doesn't have a libdef for Jest v0.21.x yet.

Answer 1

What's the right way to write Jest tests verified with Flow?

flow-typed now has all versions of Jest: https://github.com/flowtype/flow-typed/tree/master/definitions/npm
