* MockitoAnnotations.initMocks(this) method has to called to initialize annotated mocks.
*
* In above example, initMocks() is called in @Before (JUnit4) method of test's base class.
* For JUnit3 initMocks() can go to setup() method of a base class.
* You can also put initMocks() in your JUnit runner (@RunWith) or use built-in runners: {@link MockitoJUnitRunner}
