英文:
No value present, when test method getEntityById?
问题
有下一个问题，当我测试方法时，出现异常NoSuchElementException - > no value present
我的Mock
@InjectMocks
private CarServiceImpl carService;
@Mock
private CarRepository carrepo;
我的测试
@Test
void getCarById() {
Car car = new Car();
car.setId(1L);
carService.getCarById(1l);
when(carrepo.findById(1l)).thenReturn(Optional.of(car));
Car actualCar = carService.getCarById(1L);
Assertions.assertEquals(car, actualCar);
}
和服务层
@Override
public Car getCarById(Long id) {
return carrepo.findById(id).get();
}
如果有人知道问题出在哪，请帮助我。
英文:
Have next problem, when i test method i have exception NoSuchElementException - > no value present
My Mock
@InjectMocks
private CarServiceImpl carService;
@Mock
private CarRepository carrepo;
My test
@Test
void getCarById() {
Car car = new Car();
car.setId(1L);
carService.getCarById(1l);
when(carrepo.findById(1l)).thenReturn(Optional.of(car));
Car actualCar = carService.getCarById(1L);
Assertions.assertEquals (car, actualCar);
}
And Service Layer
@Override
public Car getCarById(Long id) {
return carrepo.findById(id).get();
}
if somebody know where is problem, please help me

不确定您在这个测试中想要实现什么，但在Mockito的when之前，您调用了carService.getCarById(1L);。您之后也调用了它，但我猜您最初调用getCarById(1L)时可能没有可用的值，因此会出现“no value present”消息。
英文:
Not sure what you're trying to accomplish in this test, but you're calling carService.getCarById(1L); BEFORE the Mockito when. You also call it after but I'm guessing that the initial time you call the getCarById(1L) there's no value available hence the no value present message.

这个测试将由我通过，大家谢谢！
@Test
void getCarById() {
Car car = new Car();
car.setId(1L);
when(carrepo.findById(1l)).thenReturn(Optional.of(car));
Car actualCar = carService.getCarById(1L);
Assertions.assertEquals(car, actualCar);
}
英文:
This test will passed form me, everybody tnx!
@Test
void getCarById() {
Car car = new Car();
car.setId(1L);
when(carrepo.findById(1l)).thenReturn(Optional.of(car));
Car actualCar = carService.getCarById(1L);
Assertions.assertEquals (car, actualCar);
}
