What is the method for passing command line arguments in pytest?

edit

In pytest, you can pass command line arguments by using the pytest_addoption fixture.

Here is an example:

# conftest.py

def pytest_addoption(parser):
    parser.addoption("--url", action="store", default="http://localhost", help="base URL for the tests")

# test_sample.py

def test_example(pytestconfig):
    base_url = pytestconfig.getoption("url")
    assert base_url == "http://example.com"

In this example, the pytest_addoption fixture is used to define a command line option --url. The value of this option can be retrieved in the tests using the pytestconfig fixture.

To run the test with the --url option, you would use the following command:

pytest --url=http://example.com
