monkeyrunner 自动化测试 图片对比的实现

这个功能在网上看了好多人的代码，但是总是在image.writeToFile('D:/tmp/images/black.png','png')这一句出错.查了google的API也感觉没错呀。

后来自己动脑，改成了image.writeToFile('D:/tmp/images/black.png'),竟然就成功了。后面的图片后缀竟然是可以不用加的。而且

然后loadimage后面的后缀同样可选。我是这样写的 result = MonkeyRunner.loadImageFromFile('D:/tmp/images/black.png','png')

code:

from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice, MonkeyImage

import sys,time

device = MonkeyRunner.waitForConnection()

device.wake()

device.startActivity(action = "android.media.action.IMAGE_CAPTURE")

MonkeyRunner.sleep(3.0)

image = device.takeSnapshot()

MonkeyRunner.sleep(1.0)

if (image != None):

        image.writeToFile('D:/tmp/images/black.png')

cout = 1

while(cout < 1000):

        device.startActivity(action = "android.media.action.IMAGE_CAPTURE")

        MonkeyRunner.sleep(3.0)

        image = device.takeSnapshot()

        MonkeyRunner.sleep(1.0)

        result = MonkeyRunner.loadImageFromFile('D:/tmp/images/black.png','png')

        MonkeyRunner.sleep(3.0)

        if(image.sameAs(result,0.8)):

                print "success!"

        else:

                print "fail!"

                break;

        cout += 1
