인프런 커뮤니티 질문&답변

안녕하세요 강사님. 프로젝트 진행중에 간단한 테스트 작업 중 이상한 결과가 나와서 질문드립니다..!

@Transactional
@SpringBootTest
@ActiveProfiles("test")
class ProductListResponseDtoTest {

    @Autowired ProductRepository productRepository;

    @Test
    @DisplayName("주문 상세가 주어졌을 때 ProductListResponseDto 변환")
    public void ofWithOrderDetail() {
        Product product = Product.builder()
                .price(1000L)
                .name("빵빵이")
                .productNo("123")
                .build();
        productRepository.save(product);

        OrderDetail orderDetail = OrderDetail.builder()
                .product(product)
                .price(product.getPrice())
                .quantity(2L)
                .build();

        // when
        ProductListResponseDto result = ProductListResponseDto.of(orderDetail);

        // then
        assertThat(result).extracting("productId", "productNo", "name", "price", "quantity")
                .contains(1L, "123", "빵빵이", 1000L, 2L);
    }


    @Test
    @DisplayName("상품과 수량이 주어졌을 때 ProductListResponseDto 변환")
    public void ofWithProductAndQuantity() {
        Long quantity = 2L;

        Product product = Product.builder()
                .price(1000L)
                .name("빵빵이")
                .productNo("123")
                .build();
        productRepository.save(product);

        // when
        ProductListResponseDto result = ProductListResponseDto.of(product, quantity);

        // then
        assertThat(result).extracting("productId", "productNo", "name", "price", "quantity")
                .contains(1L, "123", "빵빵이", 1000L, 2L);

    }

}

@Transactional를 통해 각 테스트가 롤백되어 productId가 모두 1L 될 것으로 예상하였습니다.

그런데 기대와 달리 실패를 하였는데요. 첫번째 테스트(ofWithOrderDetail)의 productId의 값이 2L 되었습니다.

insert문과 에러 메세지입니다.

현재 Product 엔티티의 Id는 @GeneratedValue(strategy = GenerationType.IDENTITY) 로 이루어져 있습니다.

추가적으로 @ActiveProfiles("test")에 해당하는 yml의 일부는 아래와 같습니다.

datasource:
  url: jdbc:h2:mem:~/Marketbridge
  driver-class-name: org.h2.Driver
  username: sa
  password:

jpa:
  hibernate:
    ddl-auto: none
  show-sql: true

      default_batch_fetch_size: 100
  defer-datasource-initialization: true

h2:
  console:

이런 경우는 처음이라 어디가 잘못됐는지 찾지 못하겠네요 ㅠㅠ
