基于Instrumentation Framework的开源项目AndroidMonkey简介

来源：互联网发布：淘宝客源码7.0破解版编辑：程序博客网时间：2024/06/14 21:25

在上一篇文章《MonkeyRunner和Android设备通讯方式源码分析》中本人提到MonkeyRunner跟目标安卓机器交互的其中一种方式是通过在目标机器端开启'monkey -port $port'来跟monkeyrunner建立连接进行交互的，后来打算下载安卓机器端的monkey源代码来分析下monkey是如何处理的，在google中打入关键字“android monkey source code“后定位到以下连接”https://code.google.com/p/androidmonkey“，看到是google的然后又是android，以为就是自己想要的monkey了，所以没有多看就直接下载进行分析。

过程中越看越糊涂，最大的一个疑问是怎么monkey是用instrumentation来注入event呢？这样的话它怎么做到跨进程应用的事件发送呢？因为根据本人的了解instrumentation框架是不能跨进程的，而monkey是绝对跨进程的！

[java] view plaincopy
@Override  
public int fireEvent(Instrumentation testRuner) {  
    String note;  
    if (mAction == KeyEvent.ACTION_UP) {  
        note = "ACTION_UP";  
    } else {  
        note = "ACTION_DOWN";  
    }  
  
    System.out.println(":Typing Key (" + note + "): " + mKeyCode  
            + "    // ");  
    try {  
/           testRuner.sendKeySync(getEvent());  
        testRuner.sendKeyDownUpSync(mKeyCode);  
    } catch (Exception e) {  
        System.out.println("Failed to send key (" + note + "): " + mKeyCode  
                + "    // ");  
        return MonkeyEvent.INJECT_FAIL;  
    }  
  
    return MonkeyEvent.INJECT_SUCCESS;  
}  

纠结了一段时间后返回下载地方看了下概览，很短，但很清楚的描述了这个不是我想要的monkey，而是原生monkey的一个修改后做成的android库。既然碰上了就顺便翻译下它的介绍和使用吧，反正就那么几句话，待今后有时间再来进一步研究它了，至于它是否真的如我所言不能跨进程，就留待今后或者大家来验证了。

1. 概览

官方原文:https://code.google.com/p/androidmonkey

AndroidMonkey is an Android Library. It is, in fact, a copy of the original Android Monkey Toolhttp://developer.android.com/guide/developing/tools/monkey.html and made as a library for testing and analysis (e.g. code coverage) purposes.

AndroidMonkey是一个android库。事实上它是在基于原生monkey的基础上做成的一个方便测试和分析(比如：代码覆盖率)的一个测试库。

Tester/User can easily use the library to create random test cases to test android apps with GUI.

测试人员/用户可以很方便的使用这个库来创建针对安卓gui应用的随机测试脚本

Why this library:

为什么使用这个库：

You can use this library to create random test cases for your application, with just few lines of code
使用这个库的话你可以只用几行代码就能编写出针对你的app的随机测试用例
You can add your assertions to access the state of the SUT (you can hardly do this with the Android Monkey Tool)
你可以在你的测试代码中加入断言从而很方便的去判断你的SUT(被测系统/应用)的当前情况(如果你用monkey的话是很难做到的)
You can do Coverage analysis of random testing on Android Application, this is useful for Research Purpose (like what I'm doing)
你可以通过随即测试对你的app做覆盖率分析，这对我们的研究是很有用的（像我现在所做的）（译者注：其实最后这一句话应该这样子去理解：如果你是一个公司的采购，你想去评估一个应用是否足够稳定满足你的需求，那么你就会先试用做一些前期研究）

2.使用简介

HowToUse /使用简介

Introduction/简介

Here's how to use the library/以下是介绍如何使用这个库:

Details/详情

Create an android test project／创建android项目

An Android Test project should be created first, using Android ADT [http://developer.android.com/sdk/eclipse-adt.html] Refer the the AndroidMonkey library (jar or project)

先创建一个Android Test Project项目，通过Android ADT[http://developer.android.com/sdk/eclipse-adt.html] 添加对AndroidMonkey库的引用(引用jar或者项目)

Create a test class／创建测试类

Create a normal ActivityInstrumentationTestCase2 test class, and add the following test case:

创建一个普通的ActivityInstrumentationTestCase2测试类，然后加入如下的测试用例代码：

[java] view plaincopy
public void testMonkeyEvents(){  
Display display = getActivity().getWindowManager().getDefaultDisplay(); Instrumentation inst = getInstrumentation(); PackageManager pm = getActivity().getPackageManager();  
Monkey monkey = new Monkey(display, packageToTest, inst, pm);  
for (int i = 0; i < NUM_EVENTS; i++){  
monkey.nextRandomEvent();  
}  
}
