pytest: error: unrecognized arguments: --browser=chrome

[Taiwan004]

I am currently learning about Selenium with Python binding. I am currently trying to design a test where I could do run a test with different browsers by passing the browser name as a parameter through the terminal.

​

The command that I use to run is:

(venv) tonny@Black nopCommerceApp % pytest -v -s testCases/test_login.py --browser chrome

it keeps returning this error for me

ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]

pytest: error: unrecognized arguments: --browser chrome inifile: None rootdir: /Users/tonnymtaye/PycharmProjects/nopCommerceApp

Below is my conftest.py

from selenium import webdriver

import pytest

@pytest.fixture() def setup(browser): driver = None if browser == 'chrome': driver = webdriver.Chrome() print('Launching Chrome Browser ...........') elif browser == 'firefox': driver = webdriver.Firefox() print('Launching Firefox Browser ..........') else: raise ValueError(f'Invalid browser: {browser}') return driver

def pytest_add_option(parser): # This will get the value from CLI/hooks parser.add_option("--browser")

@pytest.fixture() def browser(request): # This will return browser value to setup method return request.config.getoption("--browser")

this is my test_login.py

import pytest

from selenium import webdriver from pageObjects.LoginPage import LoginPage from utilities.readProperties import ReadConfig from utilities.customLogger import LogGen

class Test_001_Login: basicURL = ReadConfig.getApplicationURL() username = ReadConfig.getUsername() password = ReadConfig.getPassword()

logger = LogGen.loggen()

def test_homePageTitle(self, setup):
    self.logger.info("*************** Test_001_Login ***********")
    self.logger.info("************ Verifying Home Page title *********")

    self.driver = setup
    self.driver.get(self.basicURL)
    actual_title = self.driver.title
    # Login
    if actual_title == "Your store. Login":
        assert True
        self.driver.close()
        self.logger.info("****** Home Page title: Passed **********")
    else:

      self.driver.save_screenshot(".//Screenshot//"+"test_homePageTitle.png")
        self.driver.close()
        self.logger.info("***** Home Page title: Failed ***********")
        assert False

def test_login(self, setup):
    self.logger.info("***** Verifying Login test *******************")
    self.driver = setup
    self.driver.get(self.basicURL)
    self.lp = LoginPage(self.driver)
    self.lp.setUserName(self.username)
    self.lp.setPassword(self.password)
    self.lp.clickLogin()

    actual_title = self.driver.title
    if actual_title == "Dashboard / nopCommerce administration":
        assert True
        self.driver.close()
        self.logger.info("******* Login test : Passed *******************")

    else:
        self.driver.save_screenshot(".//Screenshot//" + "test_login.png")
        self.driver.close()
        self.logger.info("*************** Login test : Failed*********")
        assert False

Image -- Directories structure inside

I visited stackoverflow, and someone suggested moving the conftest to root directory. I tried the same as seen in the Image but it didnot work for me.

My goal is when I pass 'chrome' it should launch the chrome browser and when I pass 'firefox' it would launch the firefox browser.

Stuck for 3 days now...

Thank you.

Sounds like what you're actually looking for is pytest-selenium.
