编写第一个Selenium脚本
当你完成 Selenium安装 后, 便可以开始书写Selenium脚本了.
八个基本组成部分
Selenium所做的一切, 就是发送给浏览器命令, 用以执行某些操作或为信息发送请求. 您将使用Selenium执行的大部分操作, 都是以下基本命令的组合

4. 建立等待策略
将代码与浏览器的当前状态同步 是Selenium面临的最大挑战之一, 做好它是一个高级主题.
基本上, 您希望在尝试定位元素之前, 确保该元素位于页面上, 并且在尝试与该元素交互之前, 该元素处于可交互状态.
隐式等待很少是最好的解决方案, 但在这里最容易演示, 所以我们将使用它作为占位符.
