What you have shown in your example is more of a fake/stub than a true mock and it is true that if you only want pre-canned behaviour from a dependent object then often a fake can be a better choice than using a mocking framework.
This is exactly what a mocking framework will save you from doing - creating a stub or mock implementation just to be able to test the behavior of your class.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
