Question

我有一个Spring Integration测试，试图模拟一些Bean。由于某些原因，尽管我模拟了它们，但它们为NULL。这是代码段：

我要模拟的豆子

@Component
public class MockWS {

    public String callSoapClient() throws JAXBException{
        return "CallSoapCl";
    }
}

使用Bean的类

public class SmDpES2PortImpl implements ES2SmDp {
    @Autowired
    private MockWS mock;

    @Override
    public void es2DownloadProfile(ES2DownloadProfileRequest parameters) {
         try {
            LOG.info("\n\n\n TEST BEAN: " + mock.callSoapClient() + "\n\n");
          }
     }  
}

已对Bean进行模拟的Spring Boot集成测试

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class ES2SmDpApplicationTests {

    @MockBean(name="mockWS")
    MockWS mockService;

    @Test
    public void test1Es2DownloadProfile_Sucess() throws MalformedURLException, JAXBException, SOAPException {
        when(mockService.callSoapClient()).thenReturn("CallMockCLient");
    }
}

构建执行的输出： TEST BEAN：空

Answer 1

您应该模拟一个接口，而不是一个类。另外，SmDpES2PortImpl必须是Spring bean。请尝试以下操作：

接口：

public interface IMockWS {

    public String callSoapClient() throws JAXBException;
}

组件类：

@Component
public class MockWS implements IMockWS {

    @Override
    public String callSoapClient() throws JAXBException{
        return "CallSoapCl";
    }
}

服务类别：

@Service //Also @Component is a good alternative
public class SmDpES2PortImpl implements ES2SmDp {
    @Autowired
    private IMockWS mock; //Notice that you are wiring an interface

    @Override
    public void es2DownloadProfile(ES2DownloadProfileRequest parameters) {
         try {
            LOG.info("\n\n\n TEST BEAN: " + mock.callSoapClient() + "\n\n");
          }
     }  
}

测试类：

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class ES2SmDpApplicationTests {

    @MockBean
    IMockWS mockService; //Again, you are mocking the interface, not the implementing class

    @Test
    public void test1Es2DownloadProfile_Sucess() throws MalformedURLException, JAXBException, SOAPException {
        when(mockService.callSoapClient()).thenReturn("CallMockCLient");
    }
}

就我而言，以下注释组合有效：

@RunWith(SpringRunner.class) 
@SpringBootTest(classes = { ControllerThatIAmTesting.class }) 
@AutoConfigureMockMvc(addFilters = false) // if using MockMvc object

但是我必须使用@MockBean 注释显式声明我在测试类中的 ControllerThatIAmTesting 中使用的两个 Autowired 对象 - 否则 Spring 会抱怨它找不到合适的实现 - 顺便说一下，我的接口和它们的实现都在相同的对应中包

此外，使用 @WebMvcTest 而不是 @SpringBootTest（其他人建议它作为更具体的场景）导致 Spring 无法从我的 @Configuration 类中找到并初始化一些其他 @Autowired 依赖项。

MockBean在Spring Boot集成测试中不起作用
