package kdy.board.article.api;

import MSA.board.article.service.response.ArticleResponse;
import lombok.AllArgsConstructor;
import lombok.Getter;
import org.junit.jupiter.api.Test;
import org.springframework.web.client.RestClient;

public class ArticleApiTest {
    RestClient restClient = RestClient.create("http://localhost:9000");

    @Test
    void createTest() {
        ArticleResponse response = create(new ArticleCreateRequest(
                "hi", "my content", 1L, 1L
        ));
        System.out.println("response = " + response);
    }

    ArticleResponse create(ArticleCreateRequest request) {
        return restClient.post()
                .uri("/v1/articles")
                .body(request)
                .retrieve()
                .body(ArticleResponse.class);
    }

    @Getter
    @AllArgsConstructor
    static class ArticleCreateRequest {
        private String title;
        private String content;
        private Long writerId;
        private Long boardId;
    }

    @Getter
    @AllArgsConstructor
    static class ArticleUpdateRequest {
        private String title;
        private String content;
    }
}

위와 같이 코드 쓰고 Test를 진행하면 아래와 같은 에러가 뜹니다.

cmd창에서 검색해봐도 현재 9000을 쓰고 있는 서버는 없다고 뜨는데 어느 부분이 문제인 건가요?

넵! 지금 ArticleApplication도 돌리고 있고 로그도 아래와 같이 찍혀서 9000번에서 잘 돌아가고 있는 것 같습니다..

Tomcat initialized with port 9000 (http)

그래도 계속 Test 통과를 못 하고 있습니다..

learningkimkim님, 안녕하세요!

스프링부트 서버 애플리케이션이 9000번 포트에서 실행되고 있는게 맞을까요?

애플리케이션이 실행 중인 상태에서 수행해주셔야 합니다!
