MockitoAnnotations

- org.mockito.MockitoAnnotations

```
public class MockitoAnnotations
extends java.lang.Object
```
MockitoAnnotations.initMocks(this); initializes fields annotated with Mockito annotations. See also MockitoSession which not only initializes mocks but also adds extra validation for cleaner tests!
- Allows shorthand creation of objects required for testing.
- Minimizes repetitive mock creation code.
- Makes the test class more readable.
- Makes the verification error easier to read because field name is used to identify the mock.
```
   public class ArticleManagerTest extends SampleBaseTestCase {

       @Mock private ArticleCalculator calculator;
       @Mock private ArticleDatabase database;
       @Mock private UserProvider userProvider;

       private ArticleManager manager;

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

   public class SampleBaseTestCase {

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

MockitoAnnotations.initMocks(this) method has to be called to initialize annotated fields.
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 runner: MockitoJUnitRunner
