操作系统： Win10
Python： venv 3.8
Chrome： 95.0.4638.69
ChromeDriver： 95.0.4638.69
Selenium： 4.0.0

尝试运行简单的测试：

import os
import unittest
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By


class SmokeTests(unittest.TestCase):
    @classmethod
    def setUpClass(self):
        chromedriver_path = os.path.join(os.path.dirname(os.path.realpath(__file__)), r"libs\chromedriver.exe")
        ser = Service(chromedriver_path)
        self.driver = webdriver.Chrome(service=ser)
        base_url = 'https://google.com/'
        self.driver.get(base_url)

    @classmethod
    def tearDownClass(self):
        self.driver.quit()

    def test_name_in_tab_title(self):
        expected_tab_title = 'Google'
        observed_tab_title = self.driver.title
        self.assertEqual(expected_tab_title, observed_tab_title)

测试在前一天进行，当我再次启动机器时出现错误：

删除并再次添加chromedriver.exe修复了问题。
