方法不工作时Mockito

我使用mockito作为模拟框架.我在这里有一个scenerio,我的时间(abc.method()).thenReturn(value)不返回值,而是返回null.

public class DQExecWorkflowServiceImplTest {
@InjectMocks
DQExecWorkflowServiceImpl dqExecWorkflowServiceImpl = new DQExecWorkflowServiceImpl();
@Mock
private DQUtility dqUtility;
@Mock
private DqExec dqExec;
@Mock
private DqCntlDefn dqCntlDefn;
@Mock
private DqCntlWfDefn dqCntlWfDefn;
@Mock
private DqCntlWfDefnTyp dqCntlWfDefnTyp;
@Mock
private IDQControlWfDefTypeService controlWfDefTypeService;

@Before
public void setUp() throws Exception {
    dqExec = new DqExec();
    dqCntlWfDefn = new DqCntlWfDefn();
    dqUtility = new DQUtility();
    dqCntlWfDefnTyp = new DqCntlWfDefnTyp();
    dqCntlWfDefnTyp.setDqCntlWfDefnTypCd("MIN_INCLUSIVE_VAL");
    dqExecWorkflowServiceImpl
            .setControlWfDefTypeService(controlWfDefTypeService);

}

@Test
public void testExecuteWorkflow() {
    when(controlWfDefTypeService.getDqCntlWfDefnTypCd(dqCntlWfDefn))
            .thenReturn(dqCntlWfDefnTyp);
    dqExecWorkflowServiceImpl.executeWorkflow(dqExec, dqCntlWfDefn);
}

}

Java类

@Override
public DqCntlWfExec executeWorkflow(final DqExec dqExec,
        final DqCntlWfDefn dqCntlWfDefn) {
final DqCntlWfExec dqCntlWfExec = new DqCntlWfExec();
dqCntlWfExec.setDqCntlWfExecEffDt(dqUtil.getDefaultEffectiveDt());
dqCntlWfExec.setDqCntlWfExecExpDt(dqUtil.getDefaultExpiryDt());
dqCntlWfExec.setDqCntlWfDefn(dqCntlWfDefn);
dqCntlWfExec.setDqExec(dqExec);

final DqCntlWfDefnTyp dqCntlWfDefnTyp = controlWfDefTypeService
    .getDqCntlWfDefnTypCd(dqCntlWfDefn);
     String workflowType = null;
if(null!=dqCntlWfDefnTyp){
    workflowType = dqCntlWfDefnTyp.getDqCntlWfDefnTypCd();
}

当我运行测试文件时,什么时候不工作,我在buildpath中使用mockito1.8.5 jar.正在模拟服务调用但返回null值.

final DqCntlWfDefnTyp dqCntlWfDefnTyp = controlWfDefTypeService
    .getDqCntlWfDefnTypCd(dqCntlWfDefn);

该对象dqCntlWfDefnTyp为null

我以前做过这个,并没有问题什么时候,它似乎与我以前做过的文件一起工作.我对测试文件采用了相同的程序,但我无法弄清楚问题.任何人都可以帮助我
