Access cmd line arguments within from a test

[inl-pd-autotest]

Hi, how to access command line arguments within from a test_script.py?
suppose I do pytest --resolution 1280x1024 and my conftest.py is:

import pytest
def pytest_addoption(parser):
	parser.addoption('--resolution', metavar='resolution', default='1280x1024', help='specify resolution in format like that: "1280x720"')
def resolution(request):	# not sure this is needed for the example, but I need to access resolution in conftest.py's fixtures, so I have it.
	return request.config.getoption('--resolution')

and test_example.py is:

import pytest # to try 'pytestconfig.resolution'.
def test_example():
	print(resolution) # fails with NameError: name 'resolution' is not defined
	print(pytestconfig.resolution) # fails the same way. I don't know what pytestconfig really is, but docs say it is pytest config object with access to command line opts.

If you decorate your resolution function with @pytest.fixture, you should be able to add a resolution argument to your test. There's also an example here in the docs.

This still doesn't work for me:
coftest.py:

import pytest
def pytest_addoption(parser):
	parser.addoption('--resolution', metavar='resolution', default='1280x1024', help='specify resolution in format like that: "1280x720"')
@pytest.fixture
def resolution(request):
	return request.config.getoption('--resolution')

test_example.py:

def test_example(resolution):
	print(resolution) # this doesn't get printed

I've tried such cmd line calls: pytest -q --resolution 1920x1080 pytest -q --resolution 1920x1080 test_example.py

Output:

You still haven't added @pytest.fixture to resolution, so I don't know why this works. You'll also need to add -s to see output of passing tests.

Thank you! I did test with @pytest.fixture (just forgot to add it here in issue), but didn't know I needed -s to make passing tests output stuff!
