@vigneshmanick It seems like you are using a older version of the extension, can you please update?

[vigneshmanick]

Thanks for the response.

I am stuck on vscode version 1.85.2 due to glibc requirements (It's a RHEL 7.9 Machine) and i guess the python extension is also tied to that?. When i run check for updates for extension i get the message that it's upto date.

Is this is a known issue in the python extension that has been fixed in a newer version?

apologies for the delay! I will get to this shortly!

[eleanorjboyd]

Hello! From your logs it seems like you are not on the testing rewrite which may fix this issue. Please switch over and let me know if this helps!

To switch, add this setting to your users settings.json "python.experiments.optInto": ["pythonTestAdapter"]. You can confirm you have the rewrite enabled by using the command palette to set "developer set log level" to "trace" then checking for Experiment 'pythonTestAdapter' is active in your python logs.

Thanks for the response, i can confirm that with changing the pythonTestAdapter setting the tests are now recognized properly. I can now see all the tests as before.

[eleanorjboyd]

great!
