SpringBoot 테스트가 '사용 가능한 'webHandler'라는 빈이 없음'으로 실패함

SpringBoot 테스트가 '사용 가능한 'webHandler'라는 빈이 없음'으로 실패함 물어보다

1. 질문(문제점):

SpringBoot Webflux 테스트를 실행하려고 하는데 webtestclient에 대한 Spring 테스트 문서를 따르려고 하는 동안 오류가 발생 합니다No bean named 'webHandler' available .

문제가 되는 줄이 setup()에 있는 것 같습니다.

public WebTestClient webTestClient;

@Before
public void setUp() {
    webTestClient = WebTestClient.bindToApplicationContext(this.context).build();

내 어노테이션은 다음과 같습니다.

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = MyApplication.class)
@ActiveProfiles("offlineuno")

스택 추적은 다음과 같습니다.

업데이트 : 해결 방법으로 사용하고 있습니다.

 webTestClient = WebTestClient.bindToServer().baseUrl("http://localhost:8080").build();

이제 수동으로 스프링 부트 서버(IntelliJ에서)를 실행한 다음 테스트 클라이언트를 실행합니다.

2. 해결방안:

WebTestClient.bindToApplicationContextNetty에서 실행되는 애플리케이션용입니다.

귀하의 응용 프로그램이 서블릿이고 사용해야한다고 생각합니다.

MockMvcWebTestClient.bindToApplicationContext
