Answer by Ev0oD for Spring beans redefinition in unit test environment

See this tutorial with @InjectedMock annotation

It saved me a lot of time. You just use

@MockSomeClass mockedSomeClass@InjectMockClassUsingSomeClass service@Beforepublic void setUp() {    MockitoAnnotations.initMocks(this);}

and all your problems are solved. Mockito will replace the spring dependency injection with a mock. I just used it myself and it works great.
