Workaround for React test renderer not supporting refs

[joshwcomeau]

Hi,

I'm running into an issue where one of my third-party components uses refs.

This issue has already been explained and closed in #1332, but what wasn't provided was a workaround.

As it stands, snapshot testing is totally broken for the component in question, as well as its parent components. The component in question is a third-party component for integration with MapBox - is there a way to mock out the ref?

How about simply not testing the MapBox component, and mocking out that component for its parent components? I can live with that component not being tested, but I need to be able to test the components further up the tree.

Would appreciate any guidance. Recently came back to Jest after almost 2 years, and it's gotten tons better since then :)

Node v6.2.2, NPM 3.9.5

This will be part of React 15.4: facebook/react#7740

You can do jest.mock('path/to/MapBox', () => 'MapBox') which should completely stub it out.
