Question

我必须嘲笑这项服务

@Service
public class RelationServiceImpl implements RelationService {

    @Autowired
    private Map<String, Class<? extends Historiable>> modelRelations;


    @Override
    public Class<? extends Historiable> getModel(String collectionName) {

        return modelRelations.get(collectionName);
    }

}

但是我不知道如何定义测试的行为。当我尝试这个

    @Mock
    private RelationService relationService;

        @Test
        public void getHistoryOk2() throws NotFoundException, ClassNotFoundException {
            ...



 when(relationService.getModel(eq(collectionName))).thenReturn(ShipmentRequest.class);
            ...

     }

我收到这样的编译器错误：

The method thenReturn(Class<capture#1-of ? extends Historiable>) in the type OngoingStubbing<Class<capture#1-of ? extends Historiable>> is not applicable for the arguments (Class<ShipmentRequest>)

但是ShipmentRequest是Historiable的子类

Historiable
|
|-ShipmentRequest
|-...
|-...

我也尝试过这个。而不是在“ thenReturn”部分中使用ShipmentRequest.class，而是调用此方法

when(relationService.getModel(eq(collectionName))).thenReturn(method());

    private Class<? extends Historiable> method(){
            return ShipmentRequest.class;
        }

但是错误变成这样

The method thenReturn(Class<capture#1-of ? extends Historiable>) in the type OngoingStubbing<Class<capture#1-of ? extends Historiable>> is not applicable for the arguments (Class<capture#3-of ? extends Historiable>)

需要其他强制转换：

     when((Class<ShipmentRequest>)relationService.getModel(eq(collectionName))).thenReturn(ShipmentRequest.class);

具有泛型的模拟服务方法
