Jest mocks in test util
I'm using a __mocks__ folder to mock a node_module. Nice.
Example to one of the mocks, that mock 'react-relay': https://gist.github.com/robrichard/ad838e599d828a89978f54faaa2070a8
The file is located as such __mocks__/relay-react.js,
the the mock with be used in my test when jest.mock('react-relay) is executed in the testfile.
However, I have many repos that need that same mock. Is it possible to put the mock in a node_module, so to streamline my tests and do not have to copy/paste the mock everywhere?

I haven't verified this and therefore won't post it as an answer, but at a minimum I believe you could make it an NPM package and create a__mocks__/relay-react.jsthat simply re-exports the shared value fromnode_modules. Something likeexport default from "my-relay-react-mock"orexport relay as default from "my-mocks". Then Jest wouldn't know the difference.

Yeah, that would also be possible, then I think this is a better solution: github.com/facebook/jest/issues/2726#issuecomment-283100333

This is the best solution so far (as described here: https://github.com/facebook/jest/issues/2726#issuecomment-283100333):
testutils.js
import React, Component from 'react';
exports.mockRelay =
createFragmentContainer: Component => props => <Component ...props />,
...
// all the named imports you want to mock
;
then in the testfile call
jest.mock('react-relay', () => require('util/testutils').mockRelay)
