This doesnt work in practice because you might want to use different test doubles for different tests, there are several ways to mock module dependencies, on option is to use vm.runInNewContext
I did a module for this https://github.com/jfromaniello/mockuire it is like commonjs's require, but you can pass dependencies when you require a module.
