Mockito SpyBean抛出了一个未完成的StubbingException

Question

>我正在尝试使用Mockito的间谍部分模拟服务，覆盖一种方法以使其返回一致的数据进行测试，但该间谍无缘无故地抛出未完成的StubbingException。

这是我的测试类：

@SpringBootTest
@RunWith(SpringRunner.class)
public class ApplicationIT {
    private CompletableFuture<JobList> jobList;
    @SpyBean
    private Service serviceSpy;
    @Before
    public void setUp() {
        initMocks(this);
        jobList = new CompletableFuture<>();
        jobList.complete(jobList.newBuilder()
                .addAllJobs(jobTestData.getTestJob().getJobs()).build()); 
        Mockito.doReturn(jobList).when(serviceSpy).fetchJob();  
        Mockito.doNothing().when(serviceSpy).reportSuccess(Mockito.any());
    }
    @Test
    public void fetchJobCallTest() {
        Mockito.verify(serviceSpy, timeout(60000).atLeastOnce()).fetchJob();
    }
    @Test
    public void reportSuccessCallTest() {       
        Mockito.verify(serviceSpy, timeout(60000).atLeastOnce()).reportSuccess(Mockito.any());
    }
}

两个测试都失败，org.mockito.exceptions.misusing.UnfinishedStubbingException指向 Mockito.doReturn(jobList).when(serviceSpy).fetchJob(); at Mockito.doNothing().when(serviceSpy).reportSuccess(Mockito.any());

Answer 1

UnfinishedStubbingException means you are not mocking properly
this is not the right way of mocking a method... Mockito.doReturn(jobList).when(serviceSpy).fetchJob();
You can try below...
Examples of correct stubbing:
    when(mock.isOk()).thenReturn(true);
    when(mock.isOk()).thenThrow(exception);
    doThrow(exception).when(mock).someVoidMethod();
