如何过滤pytest栈追踪输出中的不必要行？

我是用pip install pytest安装的pytest，平时都是在Windows 10的命令提示符里运行它，不是在IDE里。我常用的启动命令是：

> pytest --random-order -k test_my_test_module

这里的--random-order来自pytest-random-order工具包，我每次运行pytest都会加这个参数，后来嫌麻烦，干脆写了个Python脚本自动帮我带上这个参数启动pytest。

不过就算去掉这个参数，只运行最基础的命令：

> pytest -k test_my_test_module

还是会遇到同样的输出问题。

我现在不确定是不是其他用户也会碰到这种情况——pytest会输出一大串内部实现的调用栈，这些内容对我来说完全没用，根本不想看到。正常来说，pytest是不是应该少显示这些内部细节啊？

我找过pytest输出配置相关的文档，试过--tb=short和-q这些选项，但它们好像没达到我想要的效果——还是会输出大量pytest内部的栈追踪信息。比如我得到的栈追踪片段是这样的：

...

（后面还有很长很长的内容）

我真的不需要这些pytest内部的调用细节，比如那些关于pluggy的内容，每次排查问题都要在一堆无用信息里翻找有用的部分，太麻烦了。

我想到Python的logging模块里，基础Formatter类有个formatStack(stack_info)方法，默认没做什么处理，我们可以重写这个方法，把栈追踪里不需要的行删掉。如果pytest本身没有官方的配置方式来过滤这些无用的栈行，我可能就得试试用这种方法来解决问题了。
