MemberRepositoryTest에서 저렇게 오류가 나는데 뭐가 잘못된걸까요ㅠ

package jpabook.jpashop;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class JpashopApplicationTests {

   @Test
   void contextLoads() {
   }

}

그리고 db를 실행시키지 않고 이 테스트를 돌리면 에러가 나는데 H2 db 실행여부랑 테스트 오류랑 상관이 있을까요?
