re-running a pytest test causes it to run all tests in the workspace

[DetachHead]

this started happening as of the latest vscode update (1.89.0)

to reproduce:

1. put a breakpoint in a pytest test
   
2. right click the run button and click "Debug test"
3. when it pauses on the breakpoint, click the restart button
   
4. check the debug console

Same thing happening here.

Workaround (till not fixed): install/downgrade ms-python.python == 2024.4.1 version.

[golgor]

Also started experiencing this. Thanks for the workaround @alfonzso!

[iiwolf]

This was driving me nuts and I couldn't find a thread on it! Can confirm that downgrading works

[eleanorjboyd]

Hello! We are aware of this issue and actively working to get a fix- apologies for the delay this ended up being a more complex fix than anticipated. Thanks

[DetachHead]

it seems like a recent update has changed the behavior. now instead of raising KeyError, it re-runs but it incorrectly attempts to run all tests in your project instead of the specific test you're trying to rerun

I can confirm this. It is very annoying. 😞

[lanshenghai]

Not fixed until now?

[eleanorjboyd]

Hello! I am pretty sure we fixed this but please reopen if that is not the case- thanks!

[DetachHead]

@eleanorjboyd it's still broken, it still attempts to re-run every test in the project instead of whatever test(s) were selected as i mentioned here. can this issue be re-opened please? (it doesn't let me re-open it myself)

or would you rather i raise a new issue as the behavior has changed?

Same for me

works now, thanks!
