Memory에 데이터를 넣어서 테스트 했을 때와 달리 데이터베이스를 연결해 사용할 때는 Spring 통합 테스트로 진행해야한다.
package hello.hellospring.sevice;

}
@Test

IllegalStateException e = assertThrows(IllegalStateException.class, () -> memberService.join(member2));
assertThat(e.getMessage()).isEqualTo("이미 존재하는 회원입니다.");
}
}
다음과 같이 정상적으로 수행되는 것을 확인할 수 있다.
