pytest arg parsing bug #21176
Description
Type: Bug
Behaviour
Expected vs. Actual
Running a pytest test with pytestArgs results in the error
Error while running tests: test_example
TypeError: Cannot read properties of null (reading 'testsuites')
After removing the pytestArgs from the settings.json, everything runs as expected.
Steps to reproduce:
- Open a project with a pytest (i.e. https://github.com/philippun1/pytest-vscode-parameters which I created specifically to reproduce this bug)
- Let VS Code create a settings.json (or use the one from my repo)
- Add pytestArgs (or use the one from my repo), i.e.
"python.testing.pytestArgs": [
".",
"--test_option",
"somevalue"
],
- Go to the testing tab and run the test
- Test Results tab shows the type error
- Run from the terminal instead gives no error:
pytest . --test_option somevalue
