今天尝试用monkeyrunner脚本在夜神模拟器上安装并截图QQ，但是遇到了一些问题：

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

 #连接模拟器
 device = MonkeyRunner.waitForConnection()

 #打开锁屏
 device.drag((355,1061),(621,1061),3,1)

 #安装QQ
 device.installPackage("F:\\QQ_730.apk")
 MonkeyRunner.sleep(8)

 #启动QQ
 device.startActivity(component="com.tencent.mobileqq/.activity.LoginActivity")
 MonkeyRunner.sleep(5)

 #点击登录
 device.touch(180,1170,"DOWN_AND_UP")
 MonkeyRunner.sleep(3)

 #保存截图
 result = device.takeSnapshot()
 result.writeToFile("qq.png","png")

无奈刚开始就报错了。

"SyntaxError: Non-ASCII character in file 'C:\Users\Administrator\qq.py'

这是一个语法错误，原因可能是我们脚本的注释用的是中文。我们可以在脚本开始加上#-*-coding:utf-8-*-

 #-*-coding:utf-8-*-

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

 #连接模拟器
 device = MonkeyRunner.waitForConnection()

 #打开锁屏
 device.drag((355,1061),(621,1061),3,1)

 #安装QQ
 device.installPackage("F:\\QQ_730.apk")
 MonkeyRunner.sleep(8)

 #启动QQ
 device.startActivity(component="com.tencent.mobileqq/.activity.LoginActivity")
 MonkeyRunner.sleep(5)

 #点击登录
 device.touch(180,1170,"DOWN_AND_UP")
 MonkeyRunner.sleep(3)

 #保存截图
 result = device.takeSnapshot()
 result.writeToFile("qq.png","png")

可是，又报错了：

再次尝试：

 import sys
 reload(sys)
 sys.setdefaultencoding("utf-8")

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

 #连接模拟器
 device = MonkeyRunner.waitForConnection()

 #打开锁屏
 device.drag((355,1061),(621,1061),3,1)

 #安装QQ
 device.installPackage("F:\\QQ_730.apk")
 MonkeyRunner.sleep(8)

 #启动QQ
 device.startActivity(component="com.tencent.mobileqq/.activity.LoginActivity")
 MonkeyRunner.sleep(5)

 #点击登录
 device.touch(180,1170,"DOWN_AND_UP")
 MonkeyRunner.sleep(3)

 #保存图片
 result = device.takeSnapshot()
 result.writeToFile("qq.png","png")

值得注意的两点是：

1.  检查夜神模拟器有没有连上：adb devices

如果没有连上，用adb connect 127.0.0.1:62001连接，再用adb devices检查。（详见lynnLi的博客monkeyrunner之夜神模拟器的安装与使用（二））

2.  一定要用好MonkeyRunner.sleep()

在实际的测试过程中，有的时候发现脚本业务逻辑是正确的，可是不知道为什么一旦执行起来结果却是错误的，那么有一种可能就是你的操作过快，导致界面元素没有完全展示出来就开始了后续操作，从而引起的问题。（引自《精通移动App测试实战：技术、工具和案例》，于涌 王磊 曹向志编著）

====================================9月26日更新======================================

不知是Eclipse出错概率多，还是我的python脚本问题，今天写了一段python脚本，在Elipse中运行也出现了相同的错误，解决的办法却不一样：

出现报错：

方法一：如果我加上

import sys
reload(sys)
sys.setdefaultencoding("utf-8")

报错：

方法二：如果我加上：

#-*-coding:utf-8-*-

依旧报错：

方法三：如果我加上

#coding:utf-8

反而能够正常跑下去而不报错。其中原因，待我分析之后附上。
