Is there a way in PyTest to pass command line arguments to conftest.py directly?

Question

I know that there is a way to pass args in tests itself like it was shown here, but is there a way to pass in conftest.py directly? I want to configure some common stuff for all tests this way.

Answer 1

You can make something like this:

File: conftest.py

option = None

def pytest_addoption(parser):
    parser.addoption("--arg", action="store", default="example", help="Option for making some stuff")

def pytest_configure(config):
    global option
    option = config.option

and you can access your argument with option.arg in your conftest file.
