PowerMockito未完成的存根例外

Question

我有一个私有方法，可以抛出多个异常。 我正在尝试为异常编写测试用例。 下面的代码显示了两个测试用例 这些中的每一个，当单独运行时都会成功而没有任何问题。 但是当整个测试类作为JUnit测试运行时，我得到了org.mockito.exceptions.misusing.UnfinishedStubbingException

以下是我的代码：

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@PrepareForTest(TestService.class)

public class PrivateTest {

    @MockBean
    private TestService1 testService1;

    @MockBean
    private XService xService;

    @MockBean
    private YService yService;

    @Autowired
    private TestService testService;

    @TestConfiguration
    static class ServiceTestContextConfiguration {

        @Bean
        public TestService TestService() {
            return PowerMockito.spy(new TestService());
        }
    }

    @Before
    public void setup() {
        assertNotNull(xService);
        assertNotNull(yService);
        assertNotNull(testService1);
    }

    @Test
    public void testCoordinatesFromMacIOException() throws Exception {
        PowerMockito.doThrow(new IOException()).when(testService, “methoToCall”, Mockito.anyString(), Mockito.anyString());
        ResponseEntity<ResponseModel> r = TestService.getDesired(Constant.value1, Constant.value2);
        assertEquals(r.getStatusCodeValue(), 500);
    }

    @Test
    public void testCoordinatesFromMacOAuthSigner() throws Exception {
        PowerMockito.doThrow(new OAuthMessageSignerException("Test Error")).when(testService, "methoToCall", Mockito.anyString(), Mockito.anyString());
                ResponseEntity<ResponseModel> r = TestService.getDesired(Constant.value1, Constant.value2);
        assertEquals(r.getStatusCodeValue(), 500);
    }

}

堆栈跟踪：

org.mockito.exceptions.misusing.UnfinishedStubbingException: 
Unfinished stubbing detected here:
-> at org.powermock.core.classloader.ClassloaderWrapper.runWithClassClassLoader(ClassloaderWrapper.java:51)

E.g. thenReturn() may be missing.
Examples of correct stubbing:
    when(mock.isOk()).thenReturn(true);
    when(mock.isOk()).thenThrow(exception);
    doThrow(exception).when(mock).someVoidMethod();
Hints:
 1. missing thenReturn()
 2. you are trying to stub a final method, which is not supported
 3: you are stubbing the behaviour of another mock inside before 'thenReturn' instruction if completed

我如何克服这个例外？

Answer 1

来自javadocs：

像anyObject() ， eq()这样的匹配器方法不会返回匹配器。 在内部，它们在堆栈上记录匹配器并返回虚拟值（通常为null）。 此实现是由java编译器强加的静态类型安全性。 结果是你不能在Verified / stubbed方法之外使用anyObject（），eq（）方法

所以代替：

TestService.getDesired(Mockito.anyString(), Mockito.anyString())

使用（例如）：

TestService.getDesired("", "");
