У меня есть следующий Spring Boot, который я хочу протестировать с помощью теста JUnit 5 и Mockito:
Сервис:

Код: Выделить всё

public interface FxRatesService {

Optional searchFxRates(String sourceCurrency, String targetCurrency, Instant fxTime);
}

Реализация услуги:

Код: Выделить всё

@Service
public class FxRatesServiceImpl implements FxRatesService {

private static final Logger logger = LoggerFactory.getLogger(FxRatesServiceImpl.class);

private FxRatesRepository fxRatesRepository;

public FxRatesServiceImpl() {
}

@Autowired
public FxRatesServiceImpl(FxRatesRepository fxRatesRepository) {
this.fxRatesRepository = fxRatesRepository;
}

@Override
public Optional searchFxRates(String sourceCurrency, String targetCurrency, Instant fxTime)
{
FxRates sourceCurrencyRate = fxRatesRepository.findByCurrencyAndCreatedAt(sourceCurrency, fxTime);
FxRates targetCurrencyRate = fxRatesRepository.findByCurrencyAndCreatedAt(targetCurrency, fxTime);

double sourceRate = sourceCurrencyRate.getRate();
double targetRate = targetCurrencyRate.getRate();

double bidSourceToTarget = calculateBid(sourceRate, targetRate);
double askTargetToSource = calculateAsk(targetRate, sourceRate);
double midSourceToTarget = calculateMid(bidSourceToTarget, askTargetToSource);

FxResponseDto obj = FxResponseDto.builder()
.bidRate(BigDecimal.valueOf(bidSourceToTarget))
.midRate(BigDecimal.valueOf(midSourceToTarget))
.askRate(BigDecimal.valueOf(askTargetToSource))
.build();

return Optional.of(obj);
}

// Method to calculate the bid rate of Currency A in terms of Currency B
private static double calculateBid(double bidA, double askB)
{
return bidA / askB;
}

// Method to calculate the ask rate of Currency A in terms of Currency B
private static double calculateAsk(double askA, double bidB)
{
return askA / bidB;
}

// Method to calculate the mid-rate given bid and ask rates
private static double calculateMid(double bidRate, double askRate)
{
return (bidRate + askRate) / 2.0;
}
}

@Repository
public interface FxRatesRepository extends JpaRepository, JpaSpecificationExecutor, CrudRepository {

FxRates findByCurrencyAndCreatedAt(String currency, Instant fxTime);

}

Я создал этот тест Junit:

Код: Выделить всё

@SpringBootTest
@ExtendWith(MockitoExtension.class)
public class FxRatesServiceImplTest {

@Mock
private FxRatesRepository fxRatesRepository;

@InjectMocks
private FxRatesService fxRatesService;

@InjectMocks
private FxRatesServiceImpl fxRatesServiceImpl;

private FxRates sourceCurrencyRate;
private FxRates targetCurrencyRate;
private Instant fxTime;

@BeforeEach
void init()
{
fxTime = Instant.now();

sourceCurrencyRate = new FxRates();
sourceCurrencyRate.setCurrency("USD");
sourceCurrencyRate.setCreatedAt(fxTime);
sourceCurrencyRate.setRate(1.2);

targetCurrencyRate = new FxRates();
targetCurrencyRate.setCurrency("EUR");
targetCurrencyRate.setCreatedAt(fxTime);
targetCurrencyRate.setRate(0.9);
}

@Test
public void searchFxRatesTest()
{
when(fxRatesRepository.findByCurrencyAndCreatedAt(eq("USD"), any(Instant.class)))
.thenReturn(sourceCurrencyRate);
when(fxRatesRepository.findByCurrencyAndCreatedAt(eq("EUR"), any(Instant.class)))
.thenReturn(targetCurrencyRate);

Optional  response = fxRatesServiceImpl.searchFxRates("USD", "EUR", fxTime);

assertTrue(response.isPresent());
FxResponseDto fxResponseDto = response.get();

FxRatesServiceImpl obj = new FxRatesServiceImpl();
double expectedBidRate = ReflectionTestUtils.invokeMethod(obj, "calculateBid", sourceCurrencyRate.getRate(), targetCurrencyRate.getRate());
double expectedAskRate = ReflectionTestUtils.invokeMethod(obj, "calculateAsk", targetCurrencyRate.getRate(), sourceCurrencyRate.getRate());
double expectedMidRate = ReflectionTestUtils.invokeMethod(obj, "calculateMid", expectedBidRate, expectedAskRate);

assertEquals(BigDecimal.valueOf(expectedBidRate), fxResponseDto.getBidRate());
assertEquals(BigDecimal.valueOf(expectedMidRate), fxResponseDto.getMidRate());
assertEquals(BigDecimal.valueOf(expectedAskRate), fxResponseDto.getAskRate());

}
}

Но когда я запускаю тест JUnit, я получаю ошибку:

Код: Выделить всё

Знаете ли вы, как правильно имитировать источник данных, чтобы имитировать запрос и результат в тестовом файле?
