在构造函数中传递实对象和模拟对象

Question

我有一个如下所示的Account t细节构造函数。

private final AccountDetailsRestClient accountDetailsRestClient;
private final ConstantMapService constantMapService; 

private CalculationMap calculationMap;

public AccountDetails(final AccountDetailsRestClient accountDetailsRestClient, final ConstantMapService constantMapService) {
    this.accountDetailsRestClient = accountDetailsRestClient;
    this.constantMapService = constantMapService;
    initializeConstantsData();
}

private void initializeConstantsData() {
    if (this.calculationMap == null) {
        this.calculationMap = constantMapService.getMap(java.time.LocalDate.now());
    }
}

使用Mockito，我无法初始化所有3个对象accountDetailsRestClient、constantMapService和calculationMap。如果accountDetailsRestClient不为null，则constantMapService为null，反之亦然。

Mockito测试类：

@RunWith(MockitoJUnitRunner.class)
    public class AccountDetailsTest {
    
        @Mock
        private AccountDetailsRestClient accountDetailsRestClient;
    
        @Mock(answer = RETURNS_DEEP_STUBS)
        private CalculationMap calculationMap;
    
        @InjectMocks
        private final AccountDetails sut = new AccountDetailsTestImpl(new ConstantMapServiceMock());

       @Test
        public void testMethod() {
            //left it blank to check constructor issue first
        }
    
        class AccountDetailsTestImpl extends AccountDetails {
            AccountDetailsTestImpl(final ConstantMapService constantMapService) {
                    super(accountDetailsRestClient, constantMapService);
                }
            }
    
    }

但是accountDetailsRestClient现在在构造函数中为null。

我如何在不使用PowerMock的情况下解决这个问题。要么通过更改类中的代码，要么通过更改mockito测试类？

不要使用@InjectMocks简单地用手做事，就像你几乎已经做到的那样：

AccountDetails sut = new AccountDetails(mockDependency, realObject);
