Enable a debugger to be attached to unit tests

Our current `nox`-based approach does not make it easy to attach a debugger to our unit tests. This makes debugging them time-consuming and awkward. Once we figure out a clean solution, we should document it in our Contributor's Guide

首先检查当前基于 nox 的单元测试工作流和 Contributor's Guide。确定一种将调试器附加到这些测试的简洁方法，然后在指南中记录由此得到的工作流；当 contributors 无需面对当前的调试障碍即可按其操作时，即视为完成。
