아이템 조회하는 부분에서 강의와 똑같이 오류가 발생했었는데요. 지금 버전에서는 findByItemName 혹은 findByItemNameContaining 모두 정상 작동합니다.
다른 부분에서 오류가 발생해서 찾아보니까 findItems에 작성된 JPQL에서 like 뒤에 변수 기입할 때 %를 넣지 않아서 그런 거더라고요. 넣으니 테스트 통과합니다 :-)

    @Query("select i from Item i where i.itemName like %:itemName% and i.price <= :price")
    List<Item> findItems(@Param("itemName") String itemName, @Param("price") Integer price);

저만 겪은 오류인가 싶기도 한데 혹시 몰라서 공유해봅니다. 감사합니다.

ps. 제가 겪은 에러는 문법 오류라고 알려주지 않는 것 같네요. 어렵습니다ㅠ

안녕하세요. literate_t님, 공식 서포터즈 David입니다.

공유 감사합니다.

질문자 분께서 마주한 것은 에러는 아니고, 테스트 실패로 보여집니다.

특정 Item이 올 것을 기대했으나 실제로는 아무것도 존재하지 않아서 테스트가 실패한 것 같습니다.

비교 대상이 되는 실제 값이 존재하는지부터 디버깅 해보시면 좋을 것 같습니다.

감사합니다.

아이템 조회가 되지 않아 테스트가 통과 못한 이유는 쿼리 문제였습니다.
like %:itemName%으로 해줘야 하는데 강의나, 교안에서 모두 누락되어 있었습니다.
