如何用嘲弄的Mockito ServletActionContext.getRequest（），我們使用的是Struts2的

我想是這樣的，但仍然拋出NullPointerException異常如何用嘲弄的Mockito ServletActionContext.getRequest（），我們使用的是Struts2的

@RunWith(MockitoJUnitRunner.class) 
public class MyActionTest extends BaseActionTestCase { 
     @Mock private ServletActionContext context; 

@Mock 
private serviceclass serviceMock; 
@InjectMocks 
private MyAction action; 

@Test 
public void testSave() throws Exception { 
     when(serviceMock.getTaskCode()).thenReturn("tc"); 
    action.save(); 
    verify(serviceMock).saveObject(any(Task.class)); 
}

請問您可以發佈一些更多的代碼？ –

你如何創建你的動作對象（SUT）？ –

這裏@injectMocks私人MyAction行動本身爲我創建對象，所以我打電話給我這樣的真實方法：action.mysaveMethod（）; –

HM，我會說你還需要創建動作對象，如

@InjectMocks private MyAction action = new MyAction();

請參閱http://docs.mockito.googlecode.com/hg/org/mockito/InjectMocks.html對於某些e xamples
