Hello! Could you check at the top of your logs for something that says Experiment 'pythonTestAdapter'? If none of the experiments are coming up then change the setting "python.analysis.logLevel": "Trace",` in your user settings. Let me know what it says regarding this experiment since that will narrow down if this issue is due to the testing rewrite or not. Thanks

I work in a multi-root project, but the issue also exist in single-root projects.

The adapter has multiple issues. Sometimes, it reports test status dynamically, other times not...

[eleanorjboyd]

@nlykkei thank you for the info! Apologies for the inconsistency and the bugs you are seeing, we are in the process of rolling out a new architecture for testing and experiencing some of those issues along the way. You can opt out of the experiment by going to your user setting and setting "python.experiments.optOutFrom": ["pythonTestAdapter"],. If this doesn't work let me know as this will mean it is a different issue.

To diagnose your issue further could you send over the settings you have for your pytest args and also a minimal repro that I could try? I have not encountered this error and therefore cannot investigate it further.

We appreciate your patience and help during this time! All the bugs users file are key to making our extension work and community support is essential. Thanks
