Unit test discovery error output too verbose

[gregvanl]

Testing #17039

When there is an issue with test discovery, the Test Explorer tree displays a recommendation to look at the output panel (see Output > Python).

This output is too long and includes several scroll pages of Python source code. There error output should be scoped to just the test discovery error.

Hello! I have reviewed this issue and given the architectural changes of the testing rewrite, this issue should no longer exist on the rewrite. Therefore I am going to close this issue but please comment or open a new issue if you are still seeing a problem when you try this yourself!

To use the rewrite yourself just add ”python.experiments.optInto": ["pythonTestAdapter"] to your user settings. You can confirm you have the rewrite enabled by setting your log level to trace, via the Developer: Set Log Level command in the command palette. Then check to see if Experiment 'pythonTestAdapter' is active is in your python logs.

Thanks!
