如果你还想从头学起Selenium,可以看看这个系列的文章哦!
https://www.cnblogs.com/poloyy/category/1680176.html
其次,如果你不懂前端基础知识,需要自己去补充哦,博主暂时没有总结(虽然我也会,所以我学selenium就不用复习前端了哈哈哈...)
注意,目前的实战都是流水账式写的,后面才会结合框架+PO模式
目的是为了掌握所学的Selenium基础
实战题目
- 访问: https://www.vmall.com/
- 获取一级菜单下包含哪些二级菜单,不包含查看全部
- 然后获取下面,热销单品中所有 顶部 带有 爆款字样的产品名称及价格
代码思路(人为测试时的操作步骤)
- 定位一级菜单的选项列表
- 循环列表,每次都将鼠标悬浮在当前选项上,然后打印二级菜单的列表
- 热销单品在页面下方,需要滑动页面
- 定位热销单品列表
- 循环,获取标题和价格,打印爆款
