/**
 * 
 * Allows shorthand mock creation.
 * Minimizes repetitive mock creation code.
 * Makes the test class more readable.
 * Makes the verification error easier to read because the field name is used to identify the mock.

 *  *   public class ArticleManagerTest extends SampleBaseTestCase {
 *
 *       @Mock private ArticleCalculator calculator;
 *       @Mock(name = "dbMock") private ArticleDatabase database;
 *       @Mock(answer = RETURNS_MOCKS) private UserProvider userProvider;
 *
 *       private ArticleManager manager;
 *
 *       @Before public void setup() {
 *           manager = new ArticleManager(userProvider, database, calculator);

 *
 *       @Before public void initMocks() {
 *           MockitoAnnotations.initMocks(this);
 *       }
 *   }
 * 
 *
 * 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}
