java - Mockito：监视一个spring autowrite bean，它不起作用

Question

我想在间谍一个spring bean上模拟approveActivity方法。

但在这方面，它是行不通的。

1. spring 自动写入对象是成功的。

2. 间谍对象是成功的。

3. 模拟方法抛出异常。

在此处输入代码

我不知道为什么，请帮助我！

SpringFramework 3.X 和 Mockito 2.x 和 Junit 4.X。

public class ActivityBasicSmokeTest extends AbstractSmockMockito4SpringTest {


    @Autowired
    private ActivityReduceAPI activityReduceAPI;

    @Test
    public void testForApprovingActivityStatus() throws FileNotFoundException {

        ActivityReduceAPI spyActivityReduceAPI = Mockito.spy(this.activityReduceAPI);

        // stop auto audit
        Mockito.doReturn(new ResultGeneralModel<>(true)).when(spyActivityReduceAPI)
            .approveActivity("1", 2L);  <---- this is throw Exception.

    }

}

ActivityReduceAPIImpl.java

@Override
public ResultGeneralModel<Boolean> approveActivity(String token, Long id) {
    try {
        AccountResponse account = sessionContext.getAccountFromTairByToken(token);
        ReduceActivityEntity activityEntity = activityService.get(id, account);
        ActivityParamUtil.validBeforeModified(activityEntity, ActivityStatusEnum.CREATE);
        Errors error = activityService.approveReduce(activityEntity, account);
        if (null != error) {
            return new ResultGeneralModel<>(error);
        }
        return new ResultGeneralModel<>(true);
    } catch (TfavatarBusException e) {
        return new ResultGeneralModel(ErrorUtil.getErrors(e));
    }
}

org.mockito.exceptions.misusing.UnfinishedStubbingException：此处检测到未完成的存根：在 com.taobao.film.tfavatar.domain.reduce.ActivityBasicSmokeTest.testForApprovingActivityStatus(ActivityBasicSmokeTest.java:458)

例如 thenReturn() 可能会丢失。正确的存根示例：

when(mock.isOk()).thenReturn(true);
when(mock.isOk()).thenThrow(exception);
doThrow(exception).when(mock).someVoidMethod();

提示： 1. 缺少 thenReturn() 2. 您正在尝试存根不支持的最终方法 3：您正在存根在 'thenReturn' 指令完成之前内部另一个模拟的行为

Answer 1

Edit4：最后在自己建立了一个spring 3项目之后，我可以验证cglib生成的方法确实是最终的。

打印出代理类的方法和它们的修饰符给了我这样的东西：

class test.ActivityReduceAPI$$EnhancerBySpringCGLIB$$747ceb58

methods:
...
approveActivity public final
...
CGLIB$approveActivity$1 final
...

使用 CglibHelper 类（在此处找到 https://www.thekua.com/atwork/2011/06/finding-real-object-under-spring-proxies/）我能够从代理中提取真实对象。有了这个，测试正在运行。

    @Test
    public void testForApprovingActivityStatus() {

        ActivityReduceAPI spyActivityReduceAPI = Mockito.spy((ActivityReduceAPI) new CglibHelper(activityReduceAPI).getTargetObject());

        Mockito.doReturn(new ResultGeneralModel<Boolean>(true)).when(spyActivityReduceAPI)
            .approveActivity("1", 2L);

        Assert.assertTrue(spyActivityReduceAPI.test("1", 2L));
    }
