#This is the file where all xpaths are defined

import time

#defined xpath for all the page element in that page
class ErrorMessage:

    myAccount_xpath = "//span[text()='My Account']"

    registerAccount_xpath = "//a[text()='Register']"

    submit_xpath = "//input[@type='submit']"

    FnameError_Xapth = "//div[text()='First Name must be between 1 and 32 characters!']"

        pwderror = self.driver.find_element_by_xpath(self.PwdError_Xpath).text
        assert pwderror == "Password must be between 4 and 20 characters!"

#这个文件是定义测试用例的地方

import pytest

from pages.loginfail import ErrorMessage


@pytest.mark.usefixtures("setup")
class LoginFail:

    def __init__(self):
        self.error = None

#从 xpath 类导入方法来运行测试用例

    # @pytest.fixture(autouse=True)
    def test_ra_003(self):
        self.error = ErrorMessage(self.driver)
        self.error.error_name()




#I am passing below codes in command line 
python -m pytest -m test_LoginFail.py --browser firefox --url "https://demo.opencart.com/"


And getting below errors while executing
#ERROR: usage: __main__.py [options] [file_or_dir] [file_or_dir] [...]
#__main__.py: error: unrecognized arguments: --browser --url https://demo.opencart.com/
  #inifile: None
  #rootdir: F:\PycharmPrjects\POMSelenium\testscripts

如果我使用单个浏览器启动，相同的代码将正常工作。请帮我调试这个问题。我尝试了谷歌，但我没有得到任何解决方案。在传递 --browser 和 --url 参数时，我遇到了错误。没有得到我在这里做错了什么。

我在 selenium 4.2.0、pytest 7.1.2 中也遇到了同样的问题

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


@pytest.fixture(scope="class")
def setup(request):
    global driver
    browser_name = request.config.getoption("browser_name")
    if browser_name == "chrome":
        driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))
    elif browser_name == "firefox":
        print("Firefox driver")
    elif browser_name == "IE":
        print("IE driver")
    driver.get("https://rahulshettyacademy.com/angularpractice/")
    driver.maximize_window()

    request.cls.driver = driver
    yield
    driver.close()
