Appium+Java笔记（2）截图，移动控件，双指放大图片

本文记录了使用Java Appium进行自动化测试的过程，包括酷狗App中拖动元素和相机应用中双指放大图片的场景。在尝试Java-client-4.1.2和selenium3.0版本下，通过driver.pinch()和driver.zoom()方法未能成功实现图片放大，最终通过调整等待时间至2000ms实现了双指放大功能。同时介绍了webdriver.getScreenshotAs(OutputType.FILE)用于获取截图。

之前用Python试验过的，相同的测试方法使用Java试验一遍，记录记录。

1.酷狗“听”页面拖动“乐库”和“歌单”换位置，动作前后截图

2.打开相机，浏览并放大图片

运行环境 Java1.8 ; Java-client-4.1.2 ; selemium3.0 ; Appium-linux-1.12.1.AppImage

Java中driver.pinch(WebElement l), driver.zoom(WebElement l)可以调用，但是实际使用没实现放大缩小照片的效果。

关于模拟双指拖动放大图片，没按人家的等待时间来，试验时设置模拟点击后等待0.25秒就开始移动，结果只能从移动轨迹上看出确实往两侧拖动了，但就是没放大的效果，明明类似的方法，Python设置250ms后移动就行的，Java这折腾了半天，改成跟人家一模一样的等待2000ms，成功了！( ⊙ o ⊙ )

截图方法关键也是一句 webdriver.getScreenshotAs(OutputType.FILE)，File形式，后面需要copy出去。
