스프링 통합 테스트에서 에러가 발생합니다

https://www.inflearn.com/questions/734751/java-lang-illegalstateexception-failed-to-load-applicationcontext-%EC%98%A4%EB%A5%98-%EC%A7%88%EB%AC%B8%EB%93%9C%EB%A6%BD%EB%8B%88%EB%8B%A4

위 링크에서 공식 서포터즈 David님이 properties에 spring.datasource.username:과 spring.datasource.password:를 추가하라고 조언해주셨는데 새로운 에러가 발생하였습니다...
구글링한 결과 java.lang.NumberFormatException: For input string: "spring"는 잘못된 형변환으로 자료형 불일치일 경우 발생하는 에러라는데 강사님 코드와 제 코드를 비교해봐도 어디가 잘못된건지 잘 모르겠습니다
현재 회원가입 테스트와 중복 회원 예외 테스트 둘다 같은 에러가 뜨는 것으로 보이는데 아래에 제가 작성한 코드와 에러를 첨부하였습니다
