【问题描述】：

我使用 Eclipse 中运行的 JDK 1.8 进行了带注释的 Junit 4 测试。我正在使用 Mockito 来模拟被测服务类中的 DAO。抽象类中的 runner 扩展了 SpringJUnit4ClassRunner。当我运行测试时，会调用具体 DAO 类中未实现的方法，而不是模拟的方法。我已经搜索和搜索，似乎无法找到解决方案。我做错了什么？

已解决 - 我更改了 @InjectMocks @Autowired IOrganizationsService 组织服务；删除接口和自动装配，@InjectMocks OrganizationsService organizationsService；固定在下面，DAO 被嘲笑。现在的问题是，为什么声明中的 DAO 没有使用接口模拟？

@ContextConfiguration(classes = { AppXmlConfigTest.class, AppConfig.class }, inheritLocations = false)
@WebAppConfiguration
public class MockOrganizationsServiceTest extends AbstractCoreJunit4Test {

public MockOrganizationsServiceTest() {
    super();
}

@InjectMocks
OrganizationsService organizationsService;

@Mock
IOrganizationsDao organizationsDao;

@Before
public void setupMock() {
    MockitoAnnotations.initMocks(this);
}

@Test
public void testGetOrganizations() {

    LocalDate localDate = LocalDate.now();

    List<OrganizationTypeEnum> organizationTypes = new ArrayList<OrganizationTypeEnum>();
    organizationTypes.add(OrganizationTypeEnum.All);


    List<AllocationStatusEnum> allocationStatuses = new ArrayList<AllocationStatusEnum>();
    allocationStatuses.add(AllocationStatusEnum.ALL);

    List<IOrganization> organizations = new ArrayList<IOrganization>();
    IOrganization organization = new Organization();
    organization.setOrganizationId(1);
    organizations.add(organization);

    Mockito.when(organizationsDao.getOrganizations(isA(LocalDate.class), isA(List.class), isA(List.class))).thenReturn(organizations);

    List<IOrganization> orgs = organizationsService.getOrganizations(localDate, organizationTypes, allocationStatuses);
    assertNotNull(orgs);
}
}

服务类是这样的，

public class OrganizationsService extends AbstractService implements IOrganizationsService {

@Autowired
IOrganizationsDao organizationsDao;

/**
 * @param organizationsDao the organizationsDao to set
 */
public void setOrganizationsDao(IOrganizationsDao organizationsDao) {
    this.organizationsDao = organizationsDao;
}

@Override
public List<IOrganization> getOrganizations(LocalDate effectiveDate, List<OrganizationTypeEnum> organizationTypes, List<AllocationStatusEnum> allocationStatuses) {

    return organizationsDao.getOrganizations(effectiveDate, organizationTypes, allocationStatuses);
}

DAO 就是这样，

public class OrganizationsDao extends AbstractDao implements IOrganizationsDao {

@Override
public List<IOrganization> getPendingOrganizations(LocalDate effectiveDate) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public List<IOrganization> getOrganizations(LocalDate effectiveDate, List<OrganizationTypeEnum> organizationTypeEnums,
        List<AllocationStatusEnum> allocationStatuses) {
    // TODO Auto-generated method stub
    return null;
}

【解决方案1】：

我认为这里的问题是，在模拟方法调用时，您使用 isA 作为参数。据我了解， isA 方法用于验证而不是传递参数。尝试任何方法：

Mockito.when(organizationsDao.getOrganizations(any(LocalDate.class), any(List.class), any(List.class))).thenReturn(organizations);

【讨论】：

显然，@InjectMocks 需要一个具体的类。
