Type: Bug

Behaviour

I'm working on a poetry project with pytest and pytest-describe.
Tests are not recognized by the python extension.

My .vscode/settings.json contains

"python.experiments.optInto": ["pythonTestAdapter"],

However, despite setting "Trace" in VSCode Output "Python", there's no "Experiment" in the output.

Steps to reproduce:

  1. Set up a project with pytest-describe.
  2. Configure pytest in pyproject.toml with
[tool.pytest.ini_options]
describe_prefixes = [
    "describe_",
    "when_",
    "with_",
    "without_",
    "if_",
    "unless_",
    "for_",
]
  1. Create test file in tests/convert/test_convert_command.py with nested describe structure, e.g.
def describe_convert_command():
    @pytest.fixture
    def content():
        return None
    @pytest.fixture
    def from_format():
        return None
    @pytest.fixture
    def command(content, from_format):
        return ConvertCommand(content=content, from_format=from_format)
    @pytest.fixture
    def result(command):
        return command.convert()
    def describe_init():
        def with_format_go_licenses():
            @pytest.fixture
            def from_format():
                return "go-licenses"
            def with_valid_invalid_file_format():
                @pytest.fixture
                def content():
                    return inspect.cleandoc("""some key\nsome value""")

                def it_raises_a_value_error(command):
                    with pytest.raises(ValueError):
                        command.convert()

@karthiknadig I downgraded to 2024.22.0 and then to 2024.20.0 but my problem still exists with any version. I don't think it's related to the issue you linked.
I don't see a buffer overflow either.

I did some digging and debugging into the extension code and compared it with my output:

    if kind == "function":
        if testfunc and fullname != testfunc + parameterized:
            raise should_never_reach_here(

and

extra info:
fullname: it_raises_a_value_error
testfunc: describe_convert_command.describe_init.with_format_go_licenses.with_invalid_file_format.it_raises_a_value_error
parameterized:

traceback:

fullname is fetched via _get_location from item and item.location contains only it_raises_a_value_error as third element. So to me it looks as if pytest discovery in this case doesn't deliver the required fullname, but some short name only.

Thus I believe it rather has something to do with pytest-describe and the extension not being able to determine them correctly.
WDYT? And would you mind reopening again?
Thanks

@kassi

after downgraded vscode-python extension, I also needed to clone my project to a new folder to get it working again, don't know why, I even upgraded the version again to check if it could be solved only doing this and I needed to clone into a new folder again(also downgrade again), give it a try.
