Mockito when().thenReturn calls the method unnecessarily

Question

I\'m working a bit on an inherited code. I\'ve written a test that is supposed to catch NullPointerException (for it is trying to call a method from null object)

This may help others who use annotations. If you are using annotations, may be you need to use @Mock instead of @InjectMocks. Because @InjectMocks works as @Spy and @Mock together. And @Spy keeps track of recently executed methods and you may feel that incorrect data is returned/subbed. Check these two:
