Pytest inline error reporting

[NorthIsUp]

This is a request to re-open #19401 which was closed with the following response:

Looking through this issue I think getting inline errors for pytest would be quite challenging due to the need to parse output which we also have seen can be hard to get right. That being said, I think that ask is out of scope for what is achievable in the project right now.

I agree that parsing output is hard, but pytest can also output junitxml files to a specified location, wouldn't that make the implementation quite simple?

thanks!

yes I can investigate more - good suggestion on the junitxml file
