Jest (technically, Jest snapshot testing with ReactTestRenderer) does not work with ReactDOM.findDOMNode.

I've seen where I can work around this using Jest mocks. For example, if my ChannelScanner component uses my RadioButtonSet component, which wraps react-widgets' SelectList, then putting the following code in ChannelScanner.test.js allows snapshot testing to work:

jest.mock('../../src/components/forms/RadioButtonSet', () => 'RadioButtonSet');

However, this seems to break encapsulation: RadioButtonSet's tests have to set up mocks based on the components it uses, and the transitive components that they use, and this work has to be repeated for every component.

What's the best way to handle this? Short of enabling automock, is there a good way to say, "This module knows that it needs to mock itself whenever it appears?"
