Trying to "wait for debugger" in tests doesn't work

There are lines in both LanguageServerTests.cs and DebugServerTests.cs that can be uncommented to enable debugger attachment:

https://github.com/PowerShell/PowerShellEditorServices/blob/4bb71bd93320ba9b2105e3b5d2007f09f0f4a959/test/PowerShellEditorServices.Test.Host/LanguageServerTests.cs#L53

However, trying these in VSCode, I just get a bunch of error dialogs pop up in the machine's native UI and the tests just plough on and fail. I'm guessing this option is meant for Visual Studio usage, rather than VSCode.

I'm thinking we should retire this functionality and instead add a compile-time-conditional block with something like a Console.ReadKey() that reports the process ID of the test runner (that's how I tend to do it at the moment at least).

检查 LanguageServerTests.cs 和 DebugServerTests.cs 中与调试器附加相关的代码行，从链接的 LanguageServerTests.cs 位置开始。在 VSCode 中重现该行为，并将原生错误对话框和测试执行的继续情况与预期的调试工作流进行比较。当废弃的行为被移除，或被提议的测试运行器暂停和进程识别所替代，并且测试提供了可用的附加点时，即视为完成。
