我有下面的pytest脚本 Webtest.py 其中定义了要测试的url。

from seleniumwire import webdriver
import pytest
from selenium.webdriver.chrome.options import Options

class Test_main():

    @pytest.fixture()
    def test_setup(self):

        # initiating browser
        chrome_options = Options()
        chrome_options.add_argument('--start-maximized')
        chrome_options.add_argument('--headless')

        self.driver = webdriver.Chrome(executable_path=r"drivers/chromedriver v86/chromedriver.exe",options=chrome_options)

        yield
        self.driver.close()
        self.driver.quit()
        print("Test Completed")

    def test_case01(self,test_setup):
        self.url='lifesciences.cactusglobal.com'
        self.driver.get(self.url)
        title=self.driver.title
        print(title)

我想使用 self.url 要在另一个python脚本中使用的上述脚本中的值 SSL_trial.py . 我像下面那样尝试过，但在执行之前就显示出错误。

我不知道怎么做。我知道这很基本，但非常感谢您的帮助。
