问题：无法关闭 Chrome 中的警报框。
情况：我需要在 Chrome 浏览器中关闭警报。一系列测试将向用户触发警报，例如：“您忘记了自己的名字。” 为了返回用户名字段并输入文本，我必须首先关闭警报。这在 FireFox 中完美运行，但 Chrome 中的警报被忽略。我已经阅读了很多关于此的条目，但没有一个有效。
测试代码：
from selenium import webdriver
import selenium.webdriver.chrome.webdriver
import selenium.webdriver.common.alert
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException
import unittest, time, re
class ChallengeTests(unittest.TestCase):
def setUp(self):
self.driver = webdriver.Chrome()
self.driver.implicitly_wait(5)
self.base_url = "https://www.test.com"
self.verificationErrors = []
self.accept_next_alert = True
# MISSING FIRST NAME
def test_01_missing_first_name(self):
driver = self.driver
driver.get(self.base_url + "/")
#driver.find_element_by_id("fname").send_keys("Foo")
driver.find_element_by_id("lname").send_keys("Bar")
driver.find_element_by_id("screenname").send_keys("EvilMonkey")
driver.find_element_by_id("password").send_keys("test")
driver.find_element_by_id("password2").send_keys("test")
driver.find_element_by_id("reg_button").click()
alert = self.driver.switch_to_alert()
alert.dismiss()
driver.find_element_by_id("fname").send_keys("Foo")
driver.find_element_by_id("reg_button").click()
