java使用模拟覆盖自动连线实例

Question

ServiceInstance。当对下面的URL进行PUT调用时，应该调用createInstance。为了能够测试在发送PUT请求时是否调用了正确的方法，我想模拟调用了该方法的对象（ServiceInstance）。但是，mock不会覆盖真实实例。我在这个环境中缺少什么

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { MySpringBootApplication.class })
@SpyBean(ServiceInstance.class)

public class ServiceTest {

@Autowired
ServiceInstance serviceInstance;

@BeforeClass
public static void setUp() {
    SpringApplication.run(MySpringBootApplication.class, new String[] {});
}

@Test
public void sendPutRequest() throws JSONException, ClientProtocolException, IOException {
    CloseableHttpClient httpClient = HttpClientBuilder.create().build();
    HttpPut putRequest = new HttpPut("http://localhost:8080/v2/instances/1");
    //.....

    httpClient.execute(putRequest);
    Mockito.verify(serviceInstance, Mockito.times(1)).createInstance(Mockito.any());

}

}

Answer 1

这是因为您没有使用mock，而是使用了spy，所以调用了real object和real method

不要使用SpyBean注释，尝试使用MockBean注释（它在Spring上下文中模拟bean）

Example

Answer 2

您可以为测试创建配置文件

@Profile("test")
@Configuration
public class ServiceInstanceConfiguration {
   @Bean
   @Primary
   public ServiceInstance serviceInstance() {
    return Mockito.mock(ServiceInstance.class);
   }
}

并使用配置文件“test”运行测试

@ActiveProfiles("test")
@RunWith(SpringRunner.class)
@SpringBootTest(classes = { MySpringBootApplication.class })
public class ServiceTest {

    @Autowired
    ServiceInstance serviceInstance;
  //...
