我在运行测试用例时出现以下异常:

org.mockito.exceptions.misusing.UnfinishedVerificationException: 
Missing method call for verify(mock) here:
-> at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Example of correct verification:
    verify(mock).doSomething()

Also, this error might show up because you verify either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.

测试用例有两个测试如下:

@ActiveProfiles(Profiles.TEST)
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { FullIntegrationTestConfiguration.class, BaseTestConfiguration.class, MemberCachingIntegrationTest.Config.class })
public class MemberCachingIntegrationTest {

    private static final Member MEMBER_ONE = new Member();
    private static final Member MEMBER_TWO = new Member();

    @Autowired
    private MemberRepository memberRepositoryMock;

    @After
    public void validate() {
        validateMockitoUsage();
    }

    @Test
    public void testFindByEmail() {
        when(memberRepositoryMock.findByEmail(anyString())).thenReturn(MEMBER_ONE, MEMBER_TWO);

        Member firstInvocation = memberRepositoryMock.findByEmail("foo@foo.com");
        assertThat(firstInvocation, is(MEMBER_ONE));

        Member secondInvocation = memberRepositoryMock.findByEmail("foo@foo.com");
        assertThat(secondInvocation, is(MEMBER_ONE));

        verify(memberRepositoryMock, times(1)).findByEmail("foo@foo.com");

        Member thirdInvocation = memberRepositoryMock.findByEmail("bar@bar.com");
        assertThat(thirdInvocation, is(MEMBER_TWO));

        verify(memberRepositoryMock, times(1)).findByEmail("bar@bar.com");
    }

    @Test
    public void passingInexistentEmailToSendPasswordResetShouldNotCauseNPE() {
        fail("MemberRepository's findByEmail throws NPE if email not found in db! Reason: because cache was set up not to allow null values...");
        fail("Appropriate error page not displayed when above NPE is thrown!");
    }

    @Profile(Profiles.TEST)
    @Configuration
    static class Config {

        @Bean
        public MemberRepository memberRepositoryMock() {
            return mock(MemberRepository.class);
        }
    }
}

我的问题有两个:

• 我不确定这里调用了什么:sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)... 它与反射和本地方法有关，但在我的例子中是哪个本地方法？
• 我在使用 Mockito 时出了什么问题？

编辑:

@RooJpaRepository(domainType = Member.class)
public interface MemberRepository {

    @Cacheable(value = CacheConfiguration.DATABASE_CACHE_NAME)
    Member findByEmail(String email);

    @Cacheable(CacheConfiguration.DATABASE_CACHE_NAME)
    Member findByToken(String token);

    @CacheEvict(value = CacheConfiguration.DATABASE_CACHE_NAME, key = "#result.email")
    <S extends Member> S save(S entity);
}

编辑 2:

我已经调试了测试并包含了屏幕截图，这似乎证实了 macias 所说的:

org.springframework.aop.framework.ProxyFactory: 2 interfaces [com.bignibou.repository.member.MemberRepository, org.mockito.cglib.proxy.Factory]; 1 advisors [org.springframework.cache.interceptor.BeanFactoryCacheOperationSourceAdvisor: advice bean 'null']; targetSource [SingletonTargetSource for target object [com.bignibou.repository.member.MemberRepository$$EnhancerByMockitoWithCGLIB$$1b543cbe@4cca9ed4]]; proxyTargetClass=false; optimize=false; opaque=false; exposeProxy=false; frozen=false

编辑 3:要考虑的另一件事:如果我删除或注释掉测试中的最后一行和拆卸方法，即

verify(memberRepositoryMock, times(1)).findByEmail("bar@bar.com");

和

@After
public void validate() {
        validateMockitoUsage();
}

测试顺利通过....

edit 4:我实际上拼命尝试改编以下示例:https://stackoverflow.com/a/24229350/536299那是在另一篇文章中给我的。人们确实注意到模拟是 Autowiring 的，并且测试确实使用了 spring 上下文。有人可以帮助我正确地进行测试吗？

最佳答案

sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) - 根据您提供的堆栈跟踪，mockito 在报告错误时有点困惑。它与您的问题并没有真正的关系，但无论如何这是 native 的 NativeMethodAccessorImpl.invoke0 (请参阅 grep code )。 SpringJUnit4ClassRunner 运行它，这就是它的工作方式，您无需关心。

现在谈谈您的真正问题，正如我在评论中所写，这是因为 Spring 将模拟对象包装到代理中。如果你添加

System.out.println(memberRepositoryMock.getClass());

您会在控制台中看到它不是模拟，而是那里的一些代理。 Mockito 只能 stub 模拟，所以这就是您收到错误的原因。

现在的问题可能是，如何解决这个问题。 首先，您的测试实际上并不是集成测试，因为您试图模拟存储库而不是真正测试数据访问的行为方式。在这种情况下，我会放弃使用 spring-test 而只是选择简单的 MockitoJUnitRunner。

更新:

好的，现在知道它实际上是要测试的缓存，我知道您需要用 Spring 缓存装饰模拟存储库，并且您的测试是确实是一个集成测试。

这是如何完成的。提到的一点变化 frant.hartm proposal但不使用静态引用。我认为稍微自然一些。

@ActiveProfiles(Profiles.TEST)
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { FullIntegrationTestConfiguration.class, BaseTestConfiguration.class, MemberCachingIntegrationTest.Config.class })
public class MemberCachingIntegrationTest {

    @Autowired
    private MemberRepository cachedRepository;

    @Autowired
    private MockProvider mockProvider;

    @After
    public void validate() {
        validateMockitoUsage();
    }

    @Test
    public void test() {
        when(mockProvider.get().findByEmail(anyString())).thenReturn("foo", "bar");

        String firstInvocation = cachedRepository.findByEmail("foo@foo.com");
        assertThat(firstInvocation, is("foo"));

        String secondInvocation = cachedRepository.findByEmail("foo@foo.com");
        assertThat(secondInvocation, is("foo"));

        verify(mockProvider.get(), times(1)).findByEmail("foo@foo.com");

        String thirdInvocation = cachedRepository.findByEmail("bar@bar.com");
        assertThat(thirdInvocation, is("bar"));

        verify(mockProvider.get(), times(1)).findByEmail("bar@bar.com");
    }

    @Configuration
    static class Config {

        private MemberRepository mockRepository = mock(MemberRepository.class);

        @Bean
        public MemberRepository cachedRepository() {
            return mockRepository;
        }

        @Bean
        public MockProvider mockProvider() {
            return new MockProvider(mockRepository);
        }

    }

    public static class MockProvider {

        private final MemberRepository repository;

        public MockProvider(MemberRepository repository) {
            this.repository = repository;
        }

        public MemberRepository get() {
            return this.repository;
        }

    }
}

注意:存储库返回字符串而不是成员以获得更清晰的示例

关于java - Mockito 抛出 UnfinishedVerificationException(可能与本地方法调用有关)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24467675/
