No it doesn't. Using jest.doMock with ES6 imports does. Please clarify this, because people may get wrong idea that they need to install some babel plugin to actually test a module.
This should clearly state something like: "use if you don't want to require your ES6 modules"

Changed.
The steps outlined in jest.doMock for ES6 imports are only necessary if you don't want to use `require` in your tests.
