java – Mockito吞下堆栈跟踪？

为什么Mockito吞下堆栈痕迹？例如,如果我有一个

public class Foo
{
    public void foo()
    {
        bar();
    }

    public void bar()
    {
        baz();
    }

    public void baz()
    {
        throw new RuntimeException();
    }
}

和一个测试例如

public class MockTest
{
    @Test
    public void test()
    {
        Mockito.spy(new Foo()).foo();
    }
}

抛出的异常总是看起来像

java.lang.RuntimeException

    at MockTest.test(MockTest.java:11)

    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

所以,所有的东西在哪里

Foo.baz(Foo.java:17)
MockTest.test(MockTest.java:11)

？

(这里提供的示例只是一个简化 – 我正在处理更多的indirections,类等,我不能让Mockito吞噬部分模拟堆栈跟踪的关键部分…)

解决方法

是的,mockito清理堆栈跟踪！

这段代码在工作StackTraceFilter

有不同的方法来禁用它

>自Mockito 1.10.10以来,通过mockito扩展机制提供您自己的StackTraceCleanerProvider(创建一个资源文件mockito-extensions / org.mockito.plugins.StackTraceCleanerProvider,具有您实现的限定名称)
>在自定义的IMockitoConfiguration中覆盖cleaningStackTrace方法,查看there了解更多信息.
