Selenium所用版本为3.11.0

1、第一个Selenium自动化测试脚本

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.baidu.com")


driver.find_element_by_id("kw").send_keys("Selenium")
driver.find_element_by_id("su").click()
driver.quit()

2、WebDriver中的常用方法

①点击

from selenium import webdriver

driver=webdriver.Chrome()
driver.get("https://www.baidu.com")

driver.find_element_by_id("kw").clear()
driver.find_element_by_id("kw").send_keys("selenium")
driver.find_element_by_id("su").click()

driver.quit()

②提交

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.baidu.com")

search_text=driver.find_element_by_id(kw)
search_text.send_keys(selenium)
search_text.submit()

driver.quit()

③获取属性值等

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("http://www.baidu.com")


#获得输入框的尺寸
size = driver.find_element_by_id(kw).size
print(size)

#返回百度页面底部备案信息
text=driver.find_element_by_id("bottom_layer").text
print(text)

#返回元素的属性值,可以是id、name、type或其他任意属性
attribute=driver.find_element_by_id("kw").get_attribute(type)
print(attribute)

#返回元素的结果是否可见，返回结果为True或False
result = driver.find_element_by_id("kw").is_displayed()
print(result)

driver.quit()

3、控制浏览器窗口大小

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("http://m.baidu.com")

#参数数字为像素
print("设置浏览器宽480、高800显示")
# driver.set_window_size(480,800)
driver.maximize_window()
driver.quit()

4、控制浏览器后退、前进

from selenium import webdriver

driver = webdriver.Chrome()
#访问百度首页
first_url = http://www.baidu.com
print("now access %s" %(first_url))
driver.get(first_url)

#访问新闻页
second_url = http://news.baidu.com
print("now access %s" %(second_url))
driver.get(second_url)

#返回（后退）到百度首页
print("back to %s " %(first_url))
driver.back()

#手动刷新
driver.refresh()

#前进到新闻页
print("forward to %s " %(second_url))
driver.forward()

driver.quit()

5、悬停

from selenium import webdriver

#引入ActionChains类
from selenium.webdriver import ActionChains

driver = webdriver.Chrome()
driver.get("https://www.baidu.cn")
driver.maximize_window()

#定位到要悬停的元素
above=driver.find_element_by_link_text("设置")
#对定位到的元素执行鼠标悬停操作
ActionChains(driver).move_to_element(above).perform()

6、键盘操作

from selenium import webdriver
#调用key模块
from selenium.webdriver.common.keys import Keys

#在输入框输入内容
driver = webdriver.Chrome()
driver.get("http://www.baidu.com")

#删除多输入的一个m
driver.find_element_by_id("kw").send_keys("selenium")
driver.find_element_by_id("kw").send_keys(Keys.BACK_SPACE)

#输入空格键+"教程"
driver.find_element_by_id("kw").send_keys(Keys.SPACE)
driver.find_element_by_id("kw").send_keys("教程")

#输入组合键Ctrl+a,全选输入框内容
driver.find_element_by_id("kw").send_keys(Keys.CONTROL,a)

#输入组合键Ctrl+x,剪切输入框内容
driver.find_element_by_id("kw").send_keys(Keys.CONTROL,x)

#输入组合键Ctrl+v,粘贴输入框内容
driver.find_element_by_id("kw").send_keys(Keys.CONTROL,v)

#用回车键代替单击操作
driver.find_element_by_id("su").send_keys(Keys.ENTERN)
driver.quit()

7、获得验证信息

from time import sleep
from selenium import webdriver

driver=webdriver.Chrome()
driver.get("https://www.baidu.com")
print("Before search=====================")

#打印当前页面title
title=driver.title
print("title:"+title)

#打印当前页面URL
now_url=driver.current_url
print("URL:"+now_url)

driver.find_element_by_id("kw").send_keys("selenium")
driver.find_element_by_id("su").click()
sleep(2)

print("After search========================")

#再次打印当前页面title
title=driver.title
print("title:"+title)

#再次打印当前页面URL
now_url=driver.current_url
print("URL:"+now_url)

#获取搜索结果条数
num = driver.find_element_by_class_name("nums").text
print("result:"+num)

driver.quit()
