JUnit 测试 findById 返回 null
JUnit test findById returning null
我正在尝试为服务方法（如下）编写单元测试，并且我想断言存储库中的值不为空。但我一直得到空值，而是抛出异常。我不确定我的错误在哪里，所以我们将不胜感激。
这是测试：
@ExtendWith(MockitoExtension.class)
class BookingHistoryServiceImplTest {
@Mock
BookingHistoryRepository mockBookingHistoryRepository;
@Mock
UserRepository userRepository;
@Mock
PaymentRepository paymentRepository;
@Mock
BookingHistoryRepository bookingHistoryRepository;
BookingHistoryService bookingHistoryServiceToTest;
@Mock
AccommodationRepository accommodationRepository;
private BookingHistoryEntity testBookingHistoryEntity;
private AccommodationEntity testAccommodationEntity;
private UserEntity testUser;
@BeforeEach
void setUp() {
this.testUser = new UserEntity();
this.testUser.setPassword(TEST_USER_PASSWORD).setFirstName(TEST_USER_FIRST_NAME)
.setLastName(TEST_USER_LAST_NAME).setEmail(TEST_USER_EMAIL)
.setRoles(Set.of(new UserRoleEntity().setRole(UserRoleEnum.USER))).setPhoneNumber(TEST_USER_PHONE)
.setId(TEST_USER_ID);
// this.userRepository.save(this.testUser);
this.testAccommodationEntity = new AccommodationEntity();
this.testAccommodationEntity.setName(TEST_HOTEL)
.setType(new AccommodationTypeEntity().setType(AccommodationTypeEnum.HOTEL)).setCity(TEST_CITY)
.setAddress(TEST_ADDRESS).setPostalCode(TEST_PK).setImageUrl(TEST_IMAGE).setId(TEST_HOTEL_ID);
// this.accommodationRepository.save(this.testAccommodationEntity);
this.testBookingHistoryEntity = new BookingHistoryEntity();
this.testBookingHistoryEntity.setBookingTime(LocalDateTime.now()).setCancelled(true).setEmail(TEST_USER_EMAIL)
.setFirstName(TEST_USER_FIRST_NAME).setCancelledOn(LocalDateTime.now()).setCheckIn(TEST_VALID_CHECKIN)
.setCheckOut(TEST_VALID_CHECKOUT).setGuest(this.testUser).setLastName(TEST_USER_LAST_NAME)
.setProperty(this.testAccommodationEntity).setPayment(getPaymentEntity()).setId(1L);
}
在设置中我也有这个在copy/paste
中丢失了
this.bookingHistoryServiceToTest = new BookingHistoryServiceImpl(this.bookingHistoryRepository, new ModelMapper());
@Test
void find_completed_booking_by_id_should_return_BookingHistoryEntity() {
Mockito.when(this.mockBookingHistoryRepository.findById(this.testBookingHistoryEntity.getId()))
.thenReturn(Optional.of(this.testBookingHistoryEntity));
SummaryBookingServiceModel byId = this.bookingHistoryServiceToTest.findById(TEST_BOOKING_HISTORY_ID);
System.out.println();
assertNotNull(byId);
assertEquals(TEST_BOOKING_HISTORY_ID, byId.getBookingId());
}
}
服务：
@Override

BookingHistoryEntity bookingHistoryEntity = this.bookingHistoryRepository
.findById(id).orElseThrow(() -> new ObjectNotFoundException("Booking with id " + id + " not found!"));

更新：您有 2 个 BookingHistoryRepository 模拟：
mockBookingHistoryRepositorybookingHistoryRepository
您配置了第一个，但注入了第二个 serviceToTest。所以你需要删除其中一个。 F.e。删除 bookingHistoryRepository 并注入 serviceToTest mockBookingHistoryRepository
还有一些注意事项：
- 你不应该模拟你正在测试的实例。你需要在这里删除@Mock
@Mock BookingHistoryService bookingHistoryServiceToTest
- 您需要将模拟存储库注入 serviceToTest。像这样（或使用任何其他方式通过模拟设置实例字段）
@InjectMock BookingHistoryService bookingHistoryServiceToTest
