python+chrome做UI自动化常见的坑
1、调不起chrome浏览器
需下载自己浏览器对应版本的浏览器驱动chromedriver.exe并放至python路径，下载地址：ChromeDriver Mirror
http://npm.taobao.org/mirrors/chromedriver/
2、浏览器打开多个窗口/页面弹出新页面，如何定位新页面
time.sleep(3)#切窗口操作前，一定要加上延时，待上一次点击操作要打开的窗口先打开
handles = driver.window_handles # 获取当前浏览器的所有窗口句柄
driver.switch_to.window(handles[-1]) # 切换到最新打开的窗口
driver.switch_to.window(handles[-2]) # 切换到倒数第二个打开的窗口
driver.switch_to.window(handles[0]) # 切换到最开始打开的窗口3、定位一个元素有两个值：
goods_stock_all = driver.find_elements_by_xpath('//*[@id="ywAppRoot"]/div/div/div[3]/div[2]/div[3]/div[1]/div[2]/div[1]/div')[0].text
goods_stock_2 = driver.find_elements_by_xpath('//*[@id="ywAppRoot"]/div/div/div[3]/div[2]/div[3]/div[1]/div[2]/div[1]/div/span')[0].text
order_goods_number_all = driver.find_elements_by_xpath('//*[@id="ywAppRoot"]/div/div/div[3]/div[2]/div[3]/div[1]/div[2]/div[2]/div')[0].text
order_goods_number_2 = driver.find_elements_by_xpath('//*[@id="ywAppRoot"]/div/div/div[3]/div[2]/div[3]/div[1]/div[2]/div[2]/div/span')[0].text
goods_stock = goods_stock_all.replace(goods_stock_2, '')#元素定位取到2个值，将后面的值剔除
order_goods_number = order_goods_number_all.replace(order_goods_number_2, '')样例：
#coding=utf-8
