Times, comes with a Never condition, so to make sure that a method never gets called, you would use this code: At the time of the mock setup there might be different situations which we need to implement during unit test configuration. Here’s an example: ... has some useful overloads where you can return a value based on the parameters that were sent to the mocked method. You can rate examples to help us improve the quality of examples. Any help would be greatly appreciated. Job done! This is also known as "Partial Mock".

Incidentally, if you need to you can get a reference to the method parameter by doing something like this: On line 49, we have the same setup, but tell Moq to have the function return “false” – because that is the scenario we want to test in this unit test. I was struggling earlier today, due to always forgetting how to… The solution is both elegant and hacky.
