MonkeyRunner_monkey runner下图片比对_monkeyrunner 图片对比准确率-优快云博客

本文介绍了一个利用MonkeyRunner实现的自动化测试脚本，该脚本能够通过OCR识别技术解析设备屏幕上的数学表达式，并自动计算结果，最后在屏幕上输入答案。

在python下对比两张图片是一件很容易的事情，在monkey runner下进行图片比对我还没有找到好的方法，python 中的PIL调用的是C模块，而monkey runner是java,所以不能在monkey runner中直接使用PIL库，还好上面的代码给了我解决问题的思路，在monkey runner中建立compareImage.sh，然后执行python脚本比对不就OK了吗
