We designed our API. We created a POJO that we want to be immutable. To make it easier to instantiate it, we provide a builder. But to make it even more user friendly, we made it a step builder. So whoever wants to instantiate my POJO can easily concatenate the methods, and the IDE will complete with the correct method time after time.

We wrote a method that is supposed to throw an exception in some cases and we want to test it. We have a big problem!
