How to make pytest not to read tests directory as command line argument?

Question

When I am trying to run pytest using command,

pytest testfolder/ --user=val1

testfolder/ is read as an argument in ArgumentParser().

In ArgumentParser(), I have some command line arguments where --user is only a mandatory argument and rest arguments have a default value. But this command changes the first argument's value to testfolder/, which I don't want. I want to specify the test folder name but not want it to be read as an argument of test.

Hope this help, you can try using the Parser class from pytest to command line arguments, via the addoption method which allows you to register a command line option, "After command line parsing, options are available on the pytest config object via config.option.NAME where NAME is usually set by passing a dest attribute, for example addoption("--long", dest="NAME", ...)". For example:

sample.py

def test_test_folder(test_folder):
    print(test_folder)

#def test_user(user):
#   print(user)

conftest.py

import pytest

def pytest_addoption(parser):
     parser.addoption("--test_folder", action="store", default="test", help="my option: test")
     #parser.addoption("--user", action="store", default="root", help="my option: root")

@pytest.fixture
def test_folder(request):
     return request.config.getoption("--test_folder")

#def user(request):
#     return request.config.getoption("--user")

output:

pytest -s sample.py --test_folder folder
