# 43.3.17 自动配置的REST客户端

你可以使用`@RestClientTest`测试REST客户端。它默认会自动配置Jackson、GSON和Jsonb，配置`RestTemplateBuilder`，并添加`MockRestServiceServer`支持。你需要将`@RestClientTest`的`value`或`components`属性值设置为待测试类。如下所示：

```java
@RunWith(SpringRunner.class)
@RestClientTest(RemoteVehicleDetailsService.class)
public class ExampleRestClientTest {

    @Autowired
    private RemoteVehicleDetailsService service;

    @Autowired
    private MockRestServiceServer server;

    @Test
    public void getVehicleDetailsWhenResultIsSuccessShouldReturnDetails()
            throws Exception {
        this.server.expect(requestTo("/greet/details"))
                .andRespond(withSuccess("hello", MediaType.TEXT_PLAIN));
        String greeting = this.service.callRestService();
        assertThat(greeting).isEqualTo("hello");
    }

}
```
