JUnir4, JUni5

안녕하세요, 인프런 AI 인턴입니다.

고도윤님의 질문에 답변 드립니다. 현재 발생하신 문제는 JUnit 버전에 따른 호환성 문제로 추정됩니다. 강의 중 JUnit4를 사용하셨다면, 코드에 사용된 어노테이션이나 특정 기능이 JUnit5에서 다르게 작동할 수 있습니다. 이 경우 테스트 코드 실행 시 에러가 발생할 수 있습니다.

JUnit5를 사용하고 계시면 @RunWith(SpringRunner.class) 어노테이션 대신 @ExtendWith(SpringExtension.class)을 사용해야 합니다. 또한, build.gradle 파일에 JUnit5 관련 설정이 올바르게 되어 있는지 확인해야 합니다. JUnit5를 사용할 경우, testImplementation 'org.junit.jupiter:junit-jupiter-api:5.x.x'와 같은 의존성이 포함되어 있어야 하고, JUnit4의 경우 testImplementation 'junit:junit:4.x.x'가 필요합니다.

이전 수강생들이 직면했던 유사한 문제와 해결책을 담고 있는 관련 링크입니다:
- MemberRepositoryTest 실행시 오류에서는 JUnit 버전 차이로 인한 실행 문제에 관한 질문과 답변을 확인하실 수 있습니다.

특히, 다음 링크에 있는 답변이 도움이 될 수 있습니다:
- 김영한 강사님께서 제공하신 MemberRepositoryTest 실행시 오류 해결 방법에서는 @RunWith(SpringRunner.class)를 @ExtendWith(SpringExtension.class)로 변경하는 것이 언급되었습니다.

JUnit 버전에 대한 변경 사항을 적용하고 나서도 문제가 지속된다면, IDEA의 Gradle 설정 확인, 프로젝트의 Clean & Rebuild, IntelliJ IDEA의 캐시 및 재시작 같은 추가적인 해결 방법을 시도해 볼 수 있습니다.

저는 질문자님의 이해를 돕고자 지식공유자님의 기존 답변을 참고하여 유사한 답변 링크를 추천해드리고 있습니다.
현재 베타 기능으로 답변이 만족스럽지 않을 수 있는 점 양해 부탁드립니다. 🙏
추가적으로 궁금한 점이 있으시면, 이어서 질문해 주세요. 곧 지식공유자께서 답변해 주실 것입니다.

저도 같은오류인데 미치겠네요..ㅠㅠ

지금 build.gradle 에 의존성을 추가해도 안되는데 진짜 왜이러는건가요?

// JUnit 5 의존성 추가 testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.2' testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.7.2'

안녕하세요. 고도윤님, 공식 서포터즈 OMG입니다.

질문과 댓글의 내용을 보았을 때 build.gradle의 아래 설정이 적용되어 있지 않은 것 같습니다.

적용해보시고, 해결이 안될 경우 댓글 남겨주세요.

감사합니다.

현재 지금 강의파일에 올려주신대로 JUnit4 로 해서 테스트코드를 작성한 결과도 다음과 같습니다.

package jpabook.jpashop;


import jakarta.transaction.Transactional;
import org.assertj.core.api.Assertions;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class MemberRepositoryTest {
    @Autowired
    MemberRepository memberRepository;

    @Test
    @Transactional
    @Rollback(false)
    public void testMember() {
        Member member = new Member();
        member.setUsername("memberA");
        Long savedId = memberRepository.save(member);
        Member findMember = memberRepository.find(savedId);
        Assertions.assertThat(findMember.getId()).isEqualTo(member.getId());
        Assertions.assertThat(findMember.getUsername()).isEqualTo(member.getUsername());

        Assertions.assertThat(findMember).isEqualTo(member); //JPA 엔티티 동일성 보장

    }
}
