如何模拟自动装配的Spring bean列表？

Question

我已经阅读了很多关于如何模拟Spring的bean及其自动化字段的文章.但是我无法找到有关自动装配的bean列表的信息.

具体问题

我有一个叫做的课FormValidatorManager.这个类循环遍历几个实现的验证器IFormValidator.

@Component
public class FormValidatorManager implements IValidatorManager {

    @Autowired
    private List<IFormValidator> validators;


    @Override
    public final IFieldError validate(ColumnDTO columnToValidate, String sentValue) {   
        String loweredColName = columnToValidate.getName().toLowerCase();
        IFieldError errorField = new FieldError(loweredColName);

        for (IEsmFormValidator validator : validators) {
            List<String> errrorsFound = validator.validate(columnToValidate, sentValue);

            //les erreurs ne doivent pas être cumulées.
            if(CollectionUtils.isNotEmpty(errrorsFound)){
                errorField.addErrors(errrorsFound);
                break;
            }
        }

        return errorField;
    }
}

我想测试这门课.但我找不到嘲弄validators财产的方法.

我试过的

既然IFormValidators是单身人士,我试图模仿这些豆类的几个实例,希望它们能够被反映出来FormValidatorManager.validators但却没有成功.

然后,我尝试创建一个IFormValidators注释为 的列表@Mock.通过List手动启动,我希望initMocks()注入创建的列表.那仍然没有成功.

这是我的最后一次尝试:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring/test-validator-context.xml"})
public class FormValidatorManagerTest {

    @Mock
    private RegexValidator regexValidator;

    @Mock
    private FormNotNullValidator notNullValidator;

    @Mock
    private FormDataTypeValidator dataValidator;

    @InjectMocks
    private FormValidatorManager validatorManager;

    @Mock
    private List<IEsmFormValidator> validators = new ArrayList<IEsmFormValidator>();

    @Mock
    private ColumnDTO columnDTO;

    @Before
    public void init() {

        validators.add(notNullValidator);
        validators.add(regexValidator);
        validators.add(dataValidator);

        MockitoAnnotations.initMocks(this);

        Mockito.when(columnDTO.getTitle()).thenReturn("Mock title");
        Mockito.when(columnDTO.getName()).thenReturn("Mock name");
    }



    @Test
    public void testNoErrorFound(){
        mockValidator(notNullValidator,  new ArrayList<String>());
        mockValidator(regexValidator,  new ArrayList<String>());
        mockValidator(dataValidator,  new ArrayList<String>());

        IFieldError fieldErrors = validatorManager.validate(columnDTO, "Not null value");

        Assert.assertEquals(0, fieldErrors.getErrors().size());

        verifyNumberOfValidateCalls(regexValidator, Mockito.atMost(1));
        verifyNumberOfValidateCalls(dataValidator, Mockito.atMost(1));
        verifyNumberOfValidateCalls(notNullValidator, Mockito.atMost(1));
    }



    private void mockValidator(IFormValidator validator, List<String> listToReturn){
        Mockito.when(validator.validate(Mockito.any(ColumnDTO.class), Mockito.anyString())).thenReturn( listToReturn );
    }

    private void verifyNumberOfValidateCalls(IFormValidator validator, VerificationMode verifMode){
        Mockito.verify(validator, verifMode).validate(Mockito.any(ColumnDTO.class), Mockito.anyString());
    }
}

一个NPE被抛出IFormValidator.validate(),我将被嘲笑.不应该调用具体的实现.

这会导致非常糟糕的行为,因为我对该类的一些测试是误报,而其他测试则完全失败.

我正在试图弄清楚如何模拟自动装配的bean列表,同时仍然可以模拟特定的实现.

你有想法开始解决方案吗？

Answer 1

我终于想通了...

有时候,提出问题可以让你更好地解决问题:p

问题是我在验证之前将验证器链接到列表.然后验证器为null,并且MockitAnnotations.initMocks(this)在调用时不能更新引用.

而且,为了避免迭代器问题List,我不得不使用@Spy而不是@Mock.

这是最终的解决方案:

@Mock
private EsmRegexValidator regexValidator;

@Mock
private EsmFormNotNullValidator notNullValidator;

@Mock
private EsmFormDataTypeValidator dataValidator;

@InjectMocks
private EsmFormValidatorManager validatorManager;

@Spy
private List<IEsmFormValidator> validators = new ArrayList<IEsmFormValidator>();

@Mock
private ColumnDTO columnDTO;

@Before
public void init() {

    MockitoAnnotations.initMocks(this);

    validators.add(notNullValidator);
    validators.add(regexValidator);
    validators.add(dataValidator);

    Mockito.when(columnDTO.getTitle()).thenReturn("Mock title");
    Mockito.when(columnDTO.getName()).thenReturn("Mock name");
}
