In my conftest.py I added following code

import pytest
from selenium import webdriver


def pytest_addoption(parser):
    parser.addoption(
        "--browser_name", action="store", default="chrome"
    )


@pytest.fixture(scope="class")
def setup(request):
    browser_name = request.config.getoption("--browser_name")
    if browser_name == "chrome":
        driver = webdriver.Chrome()
    elif browser_name == "firefox":
        driver = webdriver.Firefox()
    elif browser_name == "Edge":
        driver = webdriver.Edge()
    driver.get("https://rahulshettyacademy.com/angularpractice/")
    driver.maximize_window()
    request.cls.driver = driver
    yield
    driver.close()

I want to choose browser name from command line, but pytest does not recognize it when I run my tests by pytest --browser_name firefox. What might be the problem? ERROR message:

ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: unrecognized arguments: --browser_name
  inifile: None
  rootdir: /home/*****/PycharmProjects/SeleniumFramework

CodePudding user response：

Possibly an issue with how you're using the fixture, or the location of you're conftest. Perhaps you have an issue with your version of pytest? The following works with pytest-4.6.9

conftest.py

import pytest


def pytest_addoption(parser):
    parser.addoption("--browser_name", action="store", default="chrome")


@pytest.fixture(scope="class")
def setup(request):
    if (browser_name := request.config.getoption("--browser_name")) == "chrome":
        print("chrome")
    else:
        print("Not chrome")

test_foo.py

def test_foo(setup):
    pass

Then with pytest test_foo.py -s --browser_name="firefox" I get

collected 1 item                                                                                                                                                                                                  

test_foo.py Not chrome
.
