[英]How to use @RestTemplateClient with JUnit 5?
我使用的是Spring Boot 2.1.7.RELEASE和junit5。不幸的是,我遇到了@RestClientTest的問題,因為我正在獲取java.lang.IllegalStateException:由於MockServerRestTemplateCustomizer尚未綁定到RestTemplate,因此無法使用自動配置的MockRestServiceServer。 您有任何想法如何正確配置它嗎?
類似的代碼可以在junit 4中完美地工作。源代碼基於文檔https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html 。
源代碼:
@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");
}
例外:
java.lang.IllegalStateException: Unable to use auto-configured MockRestServiceServer since MockServerRestTemplateCustomizer has not been bound to a RestTemplate
at org.springframework.util.Assert.state(Assert.java:73)
at org.springframework.boot.test.autoconfigure.web.client.MockRestServiceServerAutoConfiguration$DeferredRequestExpectationManager.getDelegate(MockRestServiceServerAutoConfiguration.java:110)
at org.springframework.boot.test.autoconfigure.web.client.MockRestServiceServerAutoConfiguration$DeferredRequestExpectationManager.expectRequest(MockRestServiceServerAutoConfiguration.java:87)
at org.springframework.test.web.client.MockRestServiceServer.expect(MockRestServiceServer.java:107)
at org.springframework.test.web.client.MockRestServiceServer.expect(MockRestServiceServer.java:92)
at ExampleRestClientTest.getVehicleDetailsWhenResultIsSuccessShouldReturnDetails(ExampleRestClientTest.java:27)```
spring MockMvc會為您工作嗎?
@Autowired
private MockMvc mockMvc;
public void test() {
this.mockMvc.perform(get("/form")
.header(AUTHORIZATION, authHeader))
.andDo(print())
.andExpect(status().isOk());
}
我用最后一個彈簧靴2.1.7和junit 5測試了您的情況,一切正常。 請試試 :
