我们知道,如果要对一个网站进行自动化测试,可以使用Python的selenium对获取网页的元素进行一系列操作。同样,对于Windows应用,可以使用C#或者AutoIt(也是一种脚本语言,相比较与C#,AutoIt更适合做Windows应用的自动化脚本)捕获窗体句柄进行操作。

我们知道,如果要对一个网站进行自动化测试,可以使用Python的selenium对获取网页的元素进行一系列操作。同样,对于Windows应用,可以使用C#或者AutoIt(也是一种脚本语言,相比较与C#,AutoIt更适合做Windows应用的自动化脚本)捕获窗体句柄进行操作。

今天主要记录一下使用WPF制作可以录制自动化执行Windows操作脚本工具,类似于按键精灵的录制脚本的操作。主要使用勾子捕获鼠标键盘事件。
