org.opentest4j.AssertionFailedError: Jacoco를 사용하면서 겪은 간단한 에러

./gradlew test 를 했을 때 발생하는 문제.

 

처음 내가 작성했던 테스트 코드들을 살펴보자

그냥 하나만 테스트 했을 때 문제 없이 잘 되는데 왜 자꾸 이럴까 해결을 못했었는데

 

@AfterEach
public void end() {
    userRepository.deleteAll();
}

./gradlew test는 모든 테스트를 동시에 실행하는 것이기 때문에

첫번째로 save했던 것과 겹쳐 문제가 발생했던 것이다...
