- 에러 발생 이유
- securityfilter에서 직접 선언한 jwtVerificationFilter이 동작하는데 mockbean이 없어서 발생하는 에러
- 에러 해결 방법
- test할 때 jwtVerficationFilter와 관련된 객체의 mockbean 생성하기
@MockBean
private JwtTokenizer jwtTokenizer;
@MockBean
private CustomAuthorityUtils customAuthorityUtils;

List 선언 시 .andExpect() 메서드에서 인식 못함
- 에러
- List형 객체를 ResultActions객체.andExpect() 메서드에서 null로 인식하는 문제 발생
- 에러 해결방법
- List 객체를 ArrayList 객체 등으로 선언하기
// .andExpect() 메서드에서 null로 인식됨
List<String> list = List.of("a", "b", "c");
// list -> arrayList로 변환
// .andExpect() 메서드에서 null 값이 아닌 원하던 list 값으로 인식됨
List<string> array = list.stream().collect(Collectors.toCollection(ArrayList::new));
