Type: Bug

Behaviour

I set up a small python project (using pdm & pytest). I can run all the unit tests from within vscode using the TESTING tab. However when I try to debug a test, I will get the following error message on the TEST_RESULTS tab:

Error while running tests: test_conan_info_version_foo
TypeError: Cannot read properties of null (reading 'testsuites')

Error while running tests:
TypeError: Cannot read properties of null (reading 'testsuites')

I am using Debian Bookworm in WSL and running VSCode on Win11.

Steps to reproduce:

  1. Create new folder foo in your home directory in WSL (I tried using Debian Bookworm)
  2. cd foo
  3. run pdm init
  4. run pdm add pytest
  5. Create new file tests/foo_test.py. Content: 
    def test_foo():
    assert False
  6. Enable the vscode testing, choose: pytest, choost tests folder as test folder
  7. Run the test once. It should fail with assert False.
  8. Set a breakpoint in line 2 of foo_test.py
  9. Right-click on the red cross in line 1 of foo_test.py and choose Debug Test

The error will occur as described.

Diagnostic data

Hi! What pytest version are you using?

Hi! It looks like you are using the python extension without the testing rewrite which should fix your issue. Please opt in and give it another try. You can opt in by adding the following to your user settings: "python.experiments.optInto": ["pythonTestAdapter"],

After opting in, the debugging works :)

Thanks 👍

Hope I will not face any other issues by opting in. Will this get productive soon? I think to remember that this used to work w/o this.

The experiment is turned on for 100% of users and we will take it out of experiment and make it the only option soon!
