I've had similar problem where I tried to stub predicate expression to Find-method which contains string (which is immutable of course). No success until I've create testPredicate which I pass to stub, actual SUT and finally to assert. Below code works.
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.
