问题：无法关闭Chrome中的提醒框。
情况：我需要在Chrome浏览器中关闭提醒。一系列测试将触发用户警报，例如：“您忘记了您的名字。”为了返回用户名字段并输入文本，我必须先关闭警报。这在FireFox中完美运行，但Chrome中的警报会被忽略。我已经阅读了很多条目，但都没有。
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()

答案 0 :(得分：1)
实际上，Amey指出了我的无知。我更新了Selenium和其他物品，但不是chromedriver。主要是我。我会记得在再次发布之前检查everything。
谢谢，Amey！
