使用MOCKITO模拟Java.lang.reflect.Method

Question

我需要模拟java.lang.reflect.Method进行测试（我有动态的东西）。我们已经使用Junit Spring＆amp;编写了所有测试用例。嘲笑。但是我在为我的方面写Junit时面临问题。我们也已经写了自定义注释。请帮助我

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring/services-test.xml")
@ImportAutoConfiguration(RefreshAutoConfiguration.class)
public abstract class AbsServicesTest extends AbstractJUnit4SpringContextTests {
    
    static{
        System.setProperty("LOCAL");
    }
}

public class TaxValidatorAspectTest extends AbsServicesTest {
    
    @Autowired
    private ResourcesUtils resourcesUtil;
    
    @Mock
    private JoinPoint joinPoint;
    
    @Mock
    private MethodSignature methodSignature;
    
    @Mock
    private Method method;
    @Before
    public void setUp() throws Exception {
        MockitoAnnotations.initMocks(new TaxValidatorAspectTest());
        Mockito.when(joinPoint.getSignature()).thenReturn(methodSignature);
        Mockito.when(methodSignature.getMethod()).thenReturn(method);
    }
    
    @Test
    public void testBeforeMethod() throws IOException{
        TaxValidatorAspect taxonomyValidationAspect = new TaxValidatorAspect();
        final Object[] arguments = new Object[4];
        arguments[0] = requiredParam1;
        arguments[1] = requiredParam2;
        arguments[2] = requiredParam3;
        Mockito.when(joinPoint.getArgs()).thenReturn(arguments);
        taxonomyValidationAspect.before(joinPoint);
    }
}

我遇到的错误如下

    org.mockito.exceptions.base.MockitoException: 
    Cannot mock/spy class java.lang.reflect.Method
    Mockito cannot mock/spy because :
     - final or anonymous class

您可以使用以下行进行模拟java.lang.reflect.Method：

Method mockMethod = this.getClass().getMethod(methodName);

不允许以直截了当的方式使用模拟或间谍来为java.lang.reflect.Method！
