Annotation Type Mock


@Target(FIELD) @Retention(RUNTIME) @Documented public @interface Mock
Mark a field as a mock.
  • 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 = "database") private ArticleDatabase dbMock;
       @Mock(answer = RETURNS_MOCKS) private UserProvider userProvider;
       @Mock(extraInterfaces = {Queue.class, Observer.class}) private  articleMonitor;

       private ArticleManager manager;

       @Before public void setup() {
           manager = new ArticleManager(userProvider, database, calculator, articleMonitor);
       }
   }

   public class SampleBaseTestCase {

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

MockitoAnnotations.initMocks(this) method has to be called to initialize annotated objects. 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. Instead you can also put initMocks() in your JUnit runner (@RunWith) or use the built-in MockitoJUnitRunner.
