h2 를 2.1.214 버전을 제거 하고,
1.4.199 버젼으로 다운그레이드 하여 성공하였습니다.
지난번 다른 수업에서는 1.4.199 는 실패하고, 2.1.214 만 성공했었는데, 어렵네요.

들여 쓰기를 같이 하여 테스트 해 보았습니다.
실행해 봤는데, h2 를 끄면 오류를 내고 h2 를 켰을 때 오류를 내지 않는 것으로 봐서 정상 연결한 것 같은데, 테스트 시작시 연결로그도 없네요.
아래와 같이 나오고 h2 콘솔에서는 hello 테이블이 추가되지 않습니다.

DB 관련해서는 혹시 들여쓰기가 잘못되서 그런건 아닐까요?
테스트 시작될 때 로그 보시면 연결 정보 보실 수 있어요
이렇게 떠야 datasource 설정이 적용된것입니다
이런 식으로 뜨면 datasource를 찾지 못한거에요
테스트 할 때 datasource를 찾지 못하면 스프링부트가 임베디드 모드로(jdbc:h2:mem:XXXXX) 동작하는데 그래서 테스트는 정상적으로 성공했을 수 있어요
