I'd like to verify calls to a logger object, so that the real implementation is still called (so I can see the output during tests).
Something like
verify(logger).error(anyString())
Mockito verify() simple example It's the same as calling with times(1) argument with verify method. verify(mockList, times(1)). size(); If we want to make sure a method is called but we don't care about the argument, then we can use ArgumentMatchers with verify method.
A mock does not call the real method, it is just proxy for actual implementations and used to track interactions with it. A spy is a partial mock, that calls the real methods unless the method is explicitly stubbed. Since Mockito does not mock final methods, so stubbing a final method for spying will not help.
Mockito verifies argument values in natural java style: by using an equals() method.
you need to use spy to verify invocations on real objects.
