java - Mockito 吞下堆栈跟踪？

Question

为什么 Mockito 会吞掉堆栈跟踪？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();
    }
}

抛出的异常总是这样

    at MockTest.test(MockTest.java:11)

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

** 那么，之间的所有东西在哪里

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

?

(此处提供的示例只是一种简化——我正在处理更多的间接寻址、类等。我不能让 Mockito 吞掉部分模拟堆栈跟踪的关键部分。 .)

Answer 1

是，mockito 清理堆栈跟踪!

工作中的代码片段 StackTraceFilter

有多种方法可以禁用它

• 从 Mockito 1.10.10 开始，通过 mockito 扩展机制提供您自己的 StackTraceCleanerProvider(创建资源文件 mockito-extensions/org.mockito.plugins.StackTraceCleanerProvider 使用您的实现的限定名称)

• 重写自定义IMockitoConfiguration中的cleansStackTrace方法，看there了解更多信息。
