Add extra command line parameters to Pytest - conftest - getoption

• conftest

• In this case the option expects a value

• And we need to use getoption to get the value

• See Parser

• See argparse

def pytest_addoption(parser):
    parser.addoption("--demo")
    parser.addoption("--noisy", action='store_true')

def test_me(request):
    print(request.config.getoption("--demo"))
    print(request.config.getoption("--noisy"))

pytest -s
None
False

pytest -s --demo Hello --noisy
Hello
True
