 The call to `resetModules` wipes away the require cache. A second call to require the same module will result in a new instantiation of the same module and all of its dependencies.

 Further, we completely overhauled how the configuration system works inside of Jest.

Through the addition of all these new features, you are now able to combine Jest in more powerful ways than ever before.
