title: How to mock dependencies for unit tests with ES6 Modules
body: <p>I'm trying to fiddle with Ecmascript 6 modules using webpack + traceur to transpile to ES5 CommonJS, but I'm having trouble successfully unit testing them.</p>
  
  <p>I tried using Jest + traceur preprocessor, but the automocking and dependency names seem to get screwy, plus I can't seem to get sourceMaps to work with Jest and node-inspector debugging.</p>
  
  <p>Is there a better framework to unit test ES6 modules?</p>
