Does not mock module that require object-assign.

[dmwyatt]

Take the flux ChatAppDispatcher from the flux chat example app that uses the object-assign ponyfill.

When you are testing module X that requires ChatAppDispatcher, jest returns undefined instead of a mocked object for module X.

If you copy the relevant code out of the object-assign module and just use it right in ChatAppDispatcher.js jest then mocks appropriately.

Jest is mocking the module object-assign. So when you do assign({}, Base, Other) the assign function is just a mock and it doesn't do anything.

So you'll want to use jest.dontMock('object-assign') at the top of your test.

Thanks!. I just had this issue and found that object-assign was mocked, but didn't know how to not mock it.
