JPA 양방향 연관관계 매핑하고 테스트 코드 작성하는 과정에서 발생한 험난한 여정..

삽질 1

failed to replace datasource with an embedded database for tests
-> 실제 DB가 연결되지 않았기 때문

삽질 2

luvShort_schema 연결했더니 이미 video 테이블 있다고 하길래 테이블 없는 new_schema 연결했더니 또 없다고..
-> application.yml 설정하는 거 깜빡했음.. jpa: hibernate: ddl-auto: update로 설정!

삽질 3

not-null property references a null or transient value
-> 엔티티 저장 시 임베디드 타입을 초기화시키지 않는 경우 발생

삽질 4

양방향 매핑 테스트 코드는 통과하는데 실제 DB까보면 저장 안됨.. 필드 다 안채워서 그런가?

테스트 코드 쪽 지식이 특히 부족한데 에러 뜰 때마다 구글링으로 지식 습득하고 이해하는 거 꽤 재밌다ㅋㅋ 그래도 언제 날잡고 테스트 작성하는 법 공부해야겠다

삽질 5

테스트 코드가 통과되는데도 이런 에러가 떴음
