谢谢,麻烦在请教一个问题;浏览器的复用,为什么一直提示’Testdemo’ object has no attribute ‘driver’

  • 请注意,有问题发帖发在答疑区哈,板块不要乱发,在答疑区中置顶帖有介绍如何正确的写一个疑问贴,写出一个符合格式的疑问贴可以帮助大家更好的查看和定位问题

  • 现在帖子中的代码格式混乱,在Markdown中使用两组三个反引号```包裹,这样可以保证代码的格式统一,并且其中的特殊符号不会因为具有特殊含义而被浏览器错误的解析。

  • 关于代码中的报错,webdriver.Chrome()语句中传递的参数错了,上面定义的options参数你并没有传入,大小写注意一下哈
