Question

我用谷歌搜索了我能想到的一切无济于事。我正在运行Spring 4.3.1。

我已经继承了一个应用程序，并且正在尝试将单元测试恢复到有用的状态。

作为其中的一部分，我在单元测试中添加了以下行：

Mockito.when(udfConfigurationRepository.save(any(UDFConfiguration.class))).thenAnswer(parm -> parm.getArguments()[0]);

单元测试工作正常。然后，我为应用程序运行了一个构建，并收到以下错误：

java.lang.IllegalStateException: Failed to load ApplicationContext

在通过Spring实际测试存储库的所有测试中重新发生此错误。我唯一能想到的是，通过嘲笑这个回购，它为春天的作品搞得一团糟。

所有数据库测试都继承自此基类。

@ContextConfiguration(locations = { "/applicationContext-dao-test.xml" })
@Transactional
@TestExecutionListeners( { TransactionalTestExecutionListener.class })
public class BaseRepositoryTest extends AbstractTestNGSpringContextTests{
    public BaseRepositoryTest(){ super(); }
}

这是applicationContext-dao-test.xml：

          p:username="sa"
          p:password="" />

    <tx:annotation-driven transaction-manager="transactionManager" />
</beans>

现在所有这些测试都失败了，唯一的变化是模拟我的存储库的一行。

我觉得这与上下文有关，我可以用这种方式修复它，但似乎无法找到分离它们的正确方法。

Answer 1

如评论中所示，答案在于Reflections - Java 8 - invalid constant type。

事实证明，常量：18指的是使用java 8样式的lambdas而不是在java 8下编译的库时的问题。

因此，为了解决这个问题，我必须编写更多代码，如下所示：

Mockito.when(udfConfigurationRepository.save(any(UDFConfiguration.class))).thenAnswer(new Answer<UDFConfiguration>() {
        @Override
        public UDFConfiguration answer(InvocationOnMock invocationOnMock) throws Throwable {
            UDFConfiguration config = (UDFConfiguration) invocationOnMock.getArguments()[0];
            return config;
        }
    });

这样做修复了这个单元测试以及所有其他测试。

添加模拟中断数据库测试
