There is some additional complexity caused by the fact that: you run the loop multiple times, and behaviour of the mocks differ between first and subsequent iterations you create cached object in method under test. Its useful when we want to use the mocked object at multiple places because we avoid calling mock() method multiple times. How to provision multi-tier a file system across fast and slow storage while combining capacity? I agree in the sense that it is a viable alternative, but I disagree because the OP is only using Mockito and gives no indication of desire, or even ability to obtain and utilize a separate framework, which is less trivial in the corporate environment than it is in the academic.
