Question

我需要为此CustomerEnrollmentSoapServiceImpl服务编写一个测试用例。如何模拟enrollExtStub.enrollExt（）方法

@Service
public class CustomerEnrollmentSoapServiceImpl implements CustomerEnrollmentSoapService {


    @Override
    public EnrollExtStub.EnrollExtResponse enrollMember(LoyalHeaders loyalHeaders, EnrollExtStub.Data_type0 enrollMember)  {
        EnrollExtStub enrollExtStub = new EnrollExtStub();

        EnrollExtStub.EnrollExtResponse enrollExtResponse = enrollExtStub.enrollExt(enrollExt, messageHeader);
        return enrollExtResponse;
    }
}

Answer 1

没有干净的方法可以做到这一点。假设您真的想测试它，它看起来像生成的代码，我可能不会测试，并且会测试很多。但是，如果需要，则需要接缝。如果EnrollExtStub是无状态的，或者对其调用enrollExt不会更改内部数据，则可以将其设置为自动装配的Bean。

@Service
public class CustomerEnrollmentSoapServiceImpl implements CustomerEnrollmentSoapService {
   @Autowired
   private EnrollExtStub enrollExtStub;

    @Override
    public EnrollExtStub.EnrollExtResponse enrollMember(LoyalHeaders loyalHeaders, EnrollExtStub.Data_type0 enrollMember)  {

        EnrollExtStub.EnrollExtResponse enrollExtResponse = enrollExtStub.enrollExt(enrollExt, messageHeader);
        return enrollExtResponse;
    }
}

然后将EnrollExtStub变成一个豆子

@Configuration
public class EnrollExtStubConfig {

    @Bean
    public EnrollExtStub enrollExtStub(){
        return new EnrollExtStub();
    }
}

然后在测试中

@RunWith(MockitoJUnitRunner.class)
public class CustomerEnrollmentSoapServiceImplTest {

    @InjectMocks
    private CustomerEnrollmentSoapServiceImpl service;

    @Mock
    private EnrollExtStub enrollExtStub;
...

或者，您可以让它直接调用另一个类似于EnrollExtStubConfig的类，并在其中创建EnrollExtStub，并且可以对该类进行模拟以返回模拟EnrollExtStub。

Answer 2

@RunWith(PowerMockRunner.class)
@PrepareForTest({CustomerEnrollmentSoapServiceImpl.class})
public class CustomerEnrollmentSoapServiceImplTest  {

  @Test
  public void enrollMemberTest() throws Exception {

    EnrollExtStub enrollExtStubMock = PowerMockito.mock(EnrollExtStub.class);
    PowerMockito.whenNew(EnrollExtStub.class).thenReturn(enrollExtStubMock);

    PowerMockito.when(enrollExtStubMock.enrollExt(Matchers.anyClass(enrollExt.class), Matchers.anyClass(MessageHeader.class))
       .thenReturn(enrollExtResponse);
 }
}

如何使用Mockito模拟实例化类的方法？
