The syntax for mocking non-virtual methods is the same as mocking …Jan 23, 2014 · So for a concrete sub class (A), you should spy the object of A and then mock getMessageWriter ().

Speaking from distant memory, @duluca, for the first 5-8 years of the existence of mocking libraries (over in Java-land), mocking an interface was seen as the only appropriate thing to mock, because coupling a test+subject to the contract of a dependency was seen as looser than to coupling it to any one implementation.
