java - Mockito 使用 spring mvc 注入(inject)抛出 NotAMockException

Question

大家好，

我正在尝试在使用 spring mvc 的 Web 应用程序上使用 mockito 进行测试。当它执行这一行 "Mockito.reset(notificacaORepositoryMock);" 它抛出 "org.mockito.exceptions.misusing.NotAMockException: Argument should be a mock, but is: class com.sun .proxy.$Proxy40"

我在我的例子中看到它有效，我在这里找不到我做错了什么。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {TestContext.class, WebAppConfig.class})
@WebAppConfiguration
public class NotificacaoControllerTest {

    private MockMvc mockMvc;

    @Autowired
    private NotificacaoRepository notificacaoRepositoryMock;

    @Autowired
    private WebApplicationContext webApplicationContext;

    @Before
    public void setUp() {
        // *** Error here ***
        Mockito.reset(notificacaoRepositoryMock);

        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

我的 TestContext 是:

@Configuration
public class TestContext {

       @Bean
        public MessageSource messageSource() {
            ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();

            messageSource.setBasename("i18n/messages");
            messageSource.setUseCodeAsDefaultMessage(true);

            return messageSource;
        }

        @Bean
        public NotificacaoRepository notificacaoRepository() {
            return Mockito.mock(NotificacaoRepository.class);
        }
}

我想要模拟的类是 CrudRepository 接口(interface)

public interface NotificacaoRepository extends CrudRepository<Notificacao, Long> {
}

而且，我认为，我的 pom.xml 的相关部分是(spring 版本和 mockito)

<properties>
    <hibernate.version>4.2.0.Final</hibernate.version>
    <mysql.connector.version>5.1.21</mysql.connector.version>
    <spring.version>4.1.6.RELEASE</spring.version>
    <spring.data.version>1.8.0.RELEASE</spring.data.version>

更新

@jfcorugedo 我完全按照你说的做了尝试，但我一直收到同样的错误。我的测试上下文只是

@Configuration
public class TestContext {
        @Bean
        @Primary
        public NotificacaoRepository notificacaoRepository() {
            return Mockito.mock(NotificacaoRepository.class);
        }
}

现在我的测试类是:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {WebAppConfig.class})
@WebAppConfiguration
@Import({TestContext.class})
public class NotificacaoControllerTest {

    @Autowired
    NotificacaoRepository notificacaoRepositoryMock;

    @Before
    public void setUp() {
        Mockito.reset(notificacaoRepositoryMock); // Error >> org.mockito.exceptions.misusing.NotAMockException: Argument should be a mock, but is: class com.sun.proxy.$Proxy55
        this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

Answer 1

这是因为 Spring 围绕您的 bean 创建了一个代理。

尽量不要使用 Spring 注入(inject) mock

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {TestContext.class, WebAppConfig.class})
@WebAppConfiguration
public class NotificacaoControllerTest {

    private MockMvc mockMvc;

    private NotificacaoRepository notificacaoRepositoryMock;

    @Autowired
    private WebApplicationContext webApplicationContext;

    @Before
    public void setUp() {
        notificacaoRepositoryMock = Mockito.mock(NotificacaoRepository.class);
        Mockito.reset(notificacaoRepositoryMock);

        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }
