Python 封装Swipe实现手机屏幕滑动操作

一. 封装Swipe目的

1. Appium的滑动API：Swipe（int start x,int start y,int end x,int y,duration)
   使用前首先得获取手机屏幕的分辨率，然后根据分辨率计算得出滑动的起始和终点坐标。
   封装后的swipe，只需调用对应的方法即可实现 向上/向下/向左/向右/斜向上 常规滑动屏幕操作。
2. Appium的API，使用均依赖于webdriver的调用，必须先建立session连接才能实现swipe功能
   封装后的swipe，基于ADB command，只需手机与PC建立ADB连接即可实现swipe功能。
3. Appium的API通过建立不同的session 实现同时操作多部手机
   封装后的swipe，直接通过传入手机 serial Number 即可实现同时操作多部手机。

综上，封装后的swipe可应用于Appium自动化测试并独立于Appium，且可以实现多部手机同时运作的功能。
