Annotation Type MockNice

@Target(value=FIELD)
 @Retention(value=RUNTIME)
 @Documented
 @Inherited
public @interface MockNice

This annotation can be placed on those fields in your test class that should be mocked in a nice manner (i.e. by default allows all method calls and returns appropriate empty values (0, null or false )). This eliminates the need to setup and tear-down mocks manually which minimizes repetitive test code and makes the test more readable. In order for PowerMock to control the life-cycle of the mocks you must supply the PowerMockListener annotation to the class-level of the test case. For example when using the EasyMock API:

 @PowerMockListener(EasyMockAnnotationEnabler.class)
 public class PersonServiceTest {
 
        @MockNice
        private PersonDao personDaoMock;
 
        private PersonService classUnderTest;
 
        @Before
        public void setUp() {
                classUnderTest = new PersonService(personDaoMock);
        }
  ...
 }
 

Note that you can also create partial mocks by using the annotation. Let's say that the PersonService has a method called "getPerson" and another method called "savePerson" and these are the only two methods that you'd like to mock. Rewriting the previous example to accommodate this will give us the following test:

 @PowerMockListener(EasyMockAnnotationEnabler.class)
 public class PersonServiceTest {
 
        @MockNice({"getPerson", "savePerson"})
        private PersonDao personDaoMock;
 
        private PersonService classUnderTest;
 
        @Before
        public void setUp() {
                classUnderTest = new PersonService(personDaoMock);
        }
  ...
 }
