• 컨트롤러 코드

@PostMapping("/account/deposit")
     public ResponseEntity<?> depositAccount(@RequestBody @Valid AccountDepositRequestDto accountDepositRequestDto,
               BindingResult bindingResult) {
          AccountDepositResponseDto accountDepositResponseDto = accountService.계좌입금(accountDepositRequestDto);
          return new ResponseEntity<>(new ResponseDto<>(1, "계좌입금 성공", accountDepositResponseDto), HttpStatus.CREATED);
     }

• 포스트맨 테스트를 위한 더미 수정

@Configuration
public class DummyDevInit extends DummyObject {

     @Profile("dev") // dev만 동작, prod는 실행 안되야함
     @Bean
     CommandLineRunner init(UserRepository userRepository, AccountRepository accountRepository) {
          return (args) -> {
               // 서버 실행 시, 무조건 실행
               User ssar = userRepository.save(newUser("ssar", "쌀"));
               User cos = userRepository.save(newUser("cos", "코스"));

               Account ssarAccount1 = accountRepository.save(newAccount(1111L, ssar));
