Override Method Return Value

I want a certain method of an object to always return a certain value when running unit tests. For example.

In the unit test I want Method A to return "Bar", but in all other cases I want to return "Foo".

I don't think Mocking will work since you need to have the object reference ahead of time (at least with Moq). Any ideas?

Mocking is the tool to use for this kind of scenario. Most mocking framework will enable you to mock object A without creating the instance. For example moles from Microsoft will enable you to implement the scenario you describe.

If possible you should pass in Object A as a dependency into Object B. The dependency you can then mock out using Moq and make it return Bar when method A is called.

If object creation of A is done internally in B, then object B is not testable for this part (hence why you should pass in your dependencies).
