Pytest discovery fails

[kjohnsen]

Type: Bug

Behaviour

Expected vs. Actual

I expect discovery to work, for the explorer to populate with tests. Instead I get pytest discovery error (see Output > Python)

Steps to reproduce:

1. Click the 'refresh tests' button on the testing pane

Diagnostic data

• Python version (& distribution if applicable, e.g. Anaconda): 3.10.9
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Conda
• Value of the python.languageServer setting: Pylance

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

Hi! Could you send your pytest version?

[eleanorjboyd]

likely it is #21540. If the version matches maybe the change didn't get out in the release.

Hi! Looking into this now but if you upgrade your pytest version you should no longer experience this issue. Thanks

[kjohnsen]

I upgraded to 7.4 and it's still broken. This is what I get on Ouput->Python:

2023-07-13 17:53:48.535 [info] Discover tests for workspace name: cleo - uri: /home/kyle/dbgt/projects/cleo

2023-07-13 17:53:57.059 [info] Using result resolver for discovery

At least the test explorer populates, but when I click "refresh tests" I get an error notification Cannot read properties of undefined (reading 'test').

When I try to run them using the test explorer, the test results pane pops up and says "Finished running tests!" but none have actually been run.

On a side note, the Insiders test explorer seems to be broken a lot for Python...I usually use the command line for tests since it's broken so often. Even so, I'd like to be able to use the debugger more often.

[eleanorjboyd]

Hi! The error notification is microsoft/vscode#187770 and should be fixed now. The result panel saying "Finished running tests" and not having them run is likely a different problem. Could you check your logs and see if an error is seen there.

In the meantime, we are releasing a new infrastructure which could be your problem at this point in time as we are working out issues coming from users. This rewrite is helping with old buggy behavior but is still experimental. You can opt out of the rewrite as I get this fix in by setting this in your **user **settings: "python.experiments.optOutFrom": ["pythonTestAdapter"],. If this doesn't work let me know as this will mean it is a different issue. Thank you and I will send updates in this thread as I get a fix in.
