1). MockitoAnnotations

public class SampleBaseTestCase{

    @Before public void initMocks(){

        MockiotAnnotations.initMocks(this);
    }
}

2). RunWith

@RunWith(MockitoJUnitRunner.class)

3).

mock(xxx.class);

2. @Mock VS @InjectMocks

@Mock creates a mock. @InjectMocks creates an instance of the class and injects the mocks that are created with the @Mock(or @Spy) annotations into this instance. Note that you must use @RunWith(MockitoJUnitRunner.class) or Mockito.initMocks(this) to initialize these mocks and inject them.

Mockito.when(mockclass.methof(Mockito.any())).thenReturn(true);
