环境搭建：

1.需要配置WebTours网站

2.安装pymysql

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple  pymysql

3.mysql数据表user表内容

 实现代码

# 导入包
from selenium  import webdriver
from selenium.webdriver.support.select import Select
from time import sleep
import pymysql


conn = pymysql.connect(host='192.168.66.138',port=3306,user='root',passwd='123456',db='test')
cur = conn.cursor()
sql = 'select * from users where yhm>"zsan5"'
cur.execute(sql)
data = cur.fetchall()

# 打开浏览器
driver = webdriver.Chrome()
dt_data= []
for row in data:
    yhm = row[1]
    print(yhm)
    mm=row[2]
    print(mm)
    yq=row[3]
    print(yq)
    # 打开网址
    driver.get("http://127.0.0.1:1080/WebTours/")
    # 等待3秒
    sleep(3)
    # 关闭浏览器
    # driver.close()
    #关闭浏览器 及驱动
    # 切换框架
    driver.switch_to_default_content()
    driver.switch_to_frame("body")
    driver.switch_to_frame("info")

    driver.find_element_by_link_text("sign up now").click()

    sleep(3)
    # 跳转页面，还是需要切换框架
    driver.switch_to_default_content()
    driver.switch_to_frame("body")
    driver.switch_to_frame("info")

    driver.find_element_by_name("username").send_keys(yhm)
    driver.find_element_by_name("password").send_keys(mm)
    driver.find_element_by_name("passwordConfirm").send_keys(mm)
    driver.find_element_by_name("register").click()
    sleep(3)

    # 跳转页面，还是需要切换框架
    driver.switch_to_default_content()
    driver.switch_to_frame("body")
    driver.switch_to_frame("info")
    expect = yq
    actual = driver.find_element_by_tag_name("body").text
    # 精确匹配用in 否则用in 
    if expect in actual:
        rs ='pass'
    else:
        rs='fail'
        
    dt_data.append((rs,yhm))

print(dt_data)

# 批量更新数据
sql = 'update users set rs=%s where yhm=%s'
cur.executemany(sql,dt_data)
conn.commit()  
  
cur.close()
conn.close()
driver.quit()
