문제

Spring Boot 프로젝트에서 테스트 코드를 작성했지만 실행 시 오류 발생.
테스트 코드는 강의 내용을 기반으로 작성했으며, 강의에서는 JUnit4를 사용했으나 최신 Spring Boot는 JUnit5를 기본으로 지원. 이로 인해 JUnit4를 사용하려면 명시적인 설정이 필요.

        member.setUsername("memberA");

        // when
        Long saveId = memberRepository.save(member);
        Member findMember = memberRepository.find(saveId);

        // then

        Assertions.assertThat(findMember.getUsername()).isEqualTo(member.getUsername());
    }
