使用Mockito模拟java.lang.reflect.Method

Question

我需要为我的测试模拟java.lang.reflect.Method（我有动态的东西）。我们使用Junit spring和mockito编写了所有测试用例。但是我在为我的方面写Junit时遇到了问题。我们也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);
}
}

我收到如下错误

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

Answer 1

您可以使用下面的行来模拟java.lang.reflect.Method

方法mockMethod = this.getClass（）。getMethod（methodName）

不允许以直接的方式使用mock或spy来为java.lang.reflect.Method创建一个模拟对象！
