如何在抽象类中执行@mock（不是 Inject Mock）

Question

当我尝试 MOC 依赖类（实例变量）时，它不会被抽象类嘲笑。但它适用于所有其他类。任何想法如何解决这个问题。我知道，我可以从子类中覆盖这段代码。但我想知道是否可以通过抽象类进行覆盖。另外，我想使用 Mockito 来解决它。 目前，我在下一行得到一个 NULL 点异常，因为 mamApiDao 是 null 并且没有被嘲笑

OvpStatusResponse ovpStatusResponse = mamApiDao.updateOvpMetadataInMam(null, callbackMessage.getMediaId(), ovpStatus, publishMessage);

抽象类

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.server.ResponseStatusException;
    
        public abstract class CallbackManager {
        
            private final MamApiDao mamApiDao;
        
            public CallbackManager( MamApiDao mamApiDao) {
                this.mamApiDao = mamApiDao;
            }
           
        
            public void processCallback(CdnCallbackMessage callbackMessage, int retries, OvpStatus ovpStatus, String publishMessage) {
                // some code 
                
                //mamApiDao is NULL, it is not getting mocked
               OvpStatusResponse ovpStatusResponse = mamApiDao.updateOvpMetadataInMam(null, callbackMessage.getMediaId(), ovpStatus, publishMessage);
                
                // some code 
        
            }
            
        }

枚举类

public enum OvpStatus {

    ACTIVE("ACTIVE"),
    INACTIVE("INACTIVE"),
    ERROR("ERROR"),
    NONE("NONE");

    private String value;

    private OvpStatus(String value) {
        this.value = value;
    }

    public String getValue() {
        return this.value;
    }
}

你能像下面这样试试吗？

public class CallbackManagerTest {

@InjectMocks
CallbackManager callbackManager = Mockito.mock(CallbackManager.class, Mockito.CALLS_REAL_METHODS);

@MockBean
private MamApiDao mamApiDao;

@BeforeEach
void setUp() {
    MockitoAnnotations.openMocks(this);
  
}

//do something
