How to access command line arguments from nonpython tests

[Cameronsplaze]

I'm writing something really similar to this yaml reader here: https://docs.pytest.org/en/6.2.x/example/nonpython.html

Inside the YamlItem -> runtest method, I want to be able to check command line arguments.The old way before going to a plugin, I would load them as a fixture "cli_args" and pass that around to the testing method. I don't know how to pass a fixture into runtest, without getting "TypeError: init() missing 1 required positional argument: 'some-arg'".

If it matters, I add a bunch of "addoption" in the pytest_addoption method, then load them to a dict with "request.config.getoption" inside the fixture. Maybe I can skip the fixture, and somehow access the getoption method inside this class?

Here's the same exact example as in the link, in case you don't trust links / it gets moved:

import pytest


def pytest_collect_file(parent, path):
    if path.ext == ".yaml" and path.basename.startswith("test"):
        return YamlFile.from_parent(parent, fspath=path)


class YamlFile(pytest.File):
    def collect(self):
        # We need a yaml parser, e.g. PyYAML.
        import yaml

        raw = yaml.safe_load(self.fspath.open())
        for name, spec in sorted(raw.items()):
            yield YamlItem.from_parent(self, name=name, spec=spec)


class YamlItem(pytest.Item):
    def __init__(self, name, parent, spec):
        super().__init__(name, parent)
        self.spec = spec

    def runtest(self):
        for name, value in sorted(self.spec.items()):
            #### NOTE: THIS is where I want to see what custom cli args I used <-------
            # Some custom test execution (dumb example follows).
            if name != value:
                raise YamlException(self, name, value)

    def repr_failure(self, excinfo):
        """Called when self.runtest() raises an exception."""
        if isinstance(excinfo.value, YamlException):
            return "\n".join(
                [
                    "usecase execution failed",
                    "   spec failed: {1!r}: {2!r}".format(*excinfo.value.args),
                    "   no further details known at this point.",
                ]
            )

    def reportinfo(self):
        return self.fspath, 0, f"usecase: {self.name}"


class YamlException(Exception):
    """Custom exception for error reporting."""

I finally found how to access the config, with this block of text here https://docs.pytest.org/en/6.2.x/deprecations.html#pytest-config-global.
I'm guessing fixtures aren't supported with plugins. You're able to access the config through the pytest.Item that YamlItem is based on. It's just a self.config.getoption inside the runtest method.

Yep, fixtures are (unfortunately) somewhat tightly integrated with Python tests, with no API for plugins available to use them in a custom way.
