Improve python test discovery error reporting

[wonderfuldays021]

Currently when there's something wrong during test discovery, I need to go to Output -> Python and find the exact issue among tons of other messages.
Is it possible to click error in test explorer and show corresponding error messages?

Also in this case, other tests without issue are not shown in test explorer. This makes me think all tests in this repo cannot be discovered. Could it be made clearer like which tests are with issues and which are not.

Hello, we are aware of buggy behavior on test discovery and are working on a rewrite of how testing works in vscode. During this effort we plan on reviewing the scenarios for errors and that should fix this issue as well. The main issue which will be working on is here: #17242, and progress will be updated on this issue. Thank you!

There is now a clickable link that will take you to the output. It would be good to have it bring you to the exact line in the logs that includes the error. This more specific request will be tracked: #4205. Thanks!
