Monkey源码分析之运行流程

    /**      * Command-line entry point.      *      * @param args The command-line arguments      */     public static void main(String[] args) {         // Set the process name showing in "ps" or "top"         Process.setArgV0("com.android.commands.monkey");          int resultCode = (new Monkey()).run(args);         System.exit(resultCode);     } 

    private int run(String[] args) {     ...         if (!processOptions()) {             return -1;         }     ... }

3. 初始化测试事件源

   private int run(String[] args) {         ...         if (mScriptFileNames != null && mScriptFileNames.size() == 1) {             // script mode, ignore other options             mEventSource = new MonkeySourceScript(mRandom, mScriptFileNames.get(0), mThrottle,                     mRandomizeThrottle, mProfileWaitTime, mDeviceSleepTime);             mEventSource.setVerbose(mVerbose);              mCountEvents = false;         } else if (mScriptFileNames != null && mScriptFileNames.size() > 1) {             if (mSetupFileName != null) {                 mEventSource = new MonkeySourceRandomScript(mSetupFileName,                         mScriptFileNames, mThrottle, mRandomizeThrottle, mRandom,                         mProfileWaitTime, mDeviceSleepTime, mRandomizeScript);                 mCount++;             } else {                 mEventSource = new MonkeySourceRandomScript(mScriptFileNames,                         mThrottle, mRandomizeThrottle, mRandom,                         mProfileWaitTime, mDeviceSleepTime, mRandomizeScript);             }             mEventSource.setVerbose(mVerbose);             mCountEvents = false;         } else if (mServerPort != -1) {             try {                 mEventSource = new MonkeySourceNetwork(mServerPort);             } catch (IOException e) {                 System.out.println("Error binding to network socket.");                 return -5;             }             mCount = Integer.MAX_VALUE;         } else {             // random source by default             if (mVerbose >= 2) { // check seeding performance                 System.out.println("// Seeded: " + mSeed);             }             mEventSource = new MonkeySourceRandom(mRandom, mMainApps, mThrottle, mRandomizeThrottle);             mEventSource.setVerbose(mVerbose);             // set any of the factors that has been set             for (int i = 0; i < MonkeySourceRandom.FACTORZ_COUNT; i++) {                 if (mFactors[i] <= 0.0f) {                     ((MonkeySourceRandom) mEventSource).setFactors(i, mFactors[i]);                 }             }              // in random mode, we start with a random activity             ((MonkeySourceRandom) mEventSource).generateActivity();         }         ...         mNetworkMonitor.start();         int crashedAtCycle = runMonkeyCycles();         mNetworkMonitor.stop();         ... }

• MonkeySourceNetwork.java: 事件是从网络如monkeyrunner过来的，处理的是《MonkeyRunner源码分析之与Android设备通讯方式》描述的界面控制操作事件
• MonkeySourceNetworkVars.java: 事件也是从网络如monkeyrunner过来的，处理的是《MonkeyRunner源码分析之与Android设备通讯方式》提到的getPropery事件
• MonkeySourceNetworkViews.java:事件也是从网络如monkeyrunner过来的，处理的是《MonkeyRunner源码分析之与Android设备通讯方式》提到的Views相关的事件
• MonkeySourceRandom.java:事件是从monkey内部生成的随机事件集，也就是我们通过命令行启动monkey测试目标app的常用方式
• MonkeySourceRanodomeScript.java: 上面的随机内部数据源也可以通过指定setup脚本来创建
• MonkeySourceScript.java: 用户也可以遵循一定的规则编写monkey脚本来驱动monkey进行相关测试，与上面不同的是它不再是随机的
