Question

Hy guys，

我正在尝试在使用spring mvc的Web应用程序上使用mockito进行测试。当它执行此行“Mockito.reset（notificacaoRepositoryMock）;”时，它会抛出“org.mockito.exceptions.misusing.NotAMockException：参数应该是一个模拟，但是：class com.sun .proxy。$ Proxy40"

我在例子中看到了它并且它有效，我找不到我在这里做错了什么。

@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);
        }
}

我想要的类是一个CrudRepository接口

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

并且，我认为，我的pom.xml的相关部分是（spring version and mockito）

<properties>
    <hibernate.version>4.2.0.Final</hibernate.version>
    <mysql.connector.version>5.1.21</mysql.connector.version>

更新

@jfcorugedo我完全按照你说的做了但我一直收到同样的错误。我的测试环境只是

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

我的测试课现在是：

@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在你的bean周围创建了一个代理。

尝试不使用Spring注入模拟

@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();
    }

据我所知，您正试图用模拟版本替换 spring bean。

在这种情况下，您必须使用注释@Primary注释生成模拟的方法，因此Spring可以在每个自动装配字段中默认选择模拟对象（当然，如果它没有任何限定符）。

如果您在测试中尝试使用Spring上下文，其中包含一些真正的 bean和其他 mock bean，则必须按照以下步骤操作：< / p>

在测试文件夹中创建一个@Configuration类，该类注入要模拟的bean的模拟实例
在测试中导入此配置类

例如：

注入模拟的配置类

import static org.mockito.Mockito.mock;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

import xxx.xxx.xxx.NotificacaoRepository;

@Configuration
public class MockConfigurer {

    @Bean
    @Primary
    public NotificacaoRepository registerMock() {
        return mock(NotificacaoRepository.class);
    }
}

测试类

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

    //Now the instance injected here should be a mock object
    @Autowired
    private NotificacaoRepository notificacaoRepositoryMock;

    ...
}

Mockito使用spring mvc注入抛出NotAMockException
