1、运行环境
base=/system export CLASSPATH=$base/framework/monkey.jar trap "" HUP exec app_process $base/bin com.android.commands.monkey.Monkey $*
monkey是一个shell脚本，在目录“/system/bin/monkey”下，通过app_process执行monkey.jar
2、程序入口
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);
}
入口主函数直接调用run方法，里面主要干了三件事
- 初始化参数
- 初始化事件源
- 执行事件
3、初始化参数
调用processOptions方法初始化
private boolean processOptions() {
// quick (throwaway) check for unadorned command
if (mArgs.length < 1) {
showUsage();
return false;
}
try {
String opt;
while ((opt = nextOption()) != null) {
if (opt.equals("-s")) {
mSeed = nextOptionLong("Seed");
} else if (opt.equals("-p")) {
mValidPackages.add(nextOptionData());
} else if (opt.equals("-c")) {
mMainCategories.add(nextOptionData());
} else if (opt.equals("-v")) {
mVerbose += 1;
} else if (opt.equals("--ignore-crashes")) {
mIgnoreCrashes = true;
} else if (opt.equals("--ignore-timeouts")) {
mIgnoreTimeouts = true;
} else if (opt.equals("--ignore-security-exceptions")) {
mIgnoreSecurityExceptions = true;
} else if (opt.equals("--monitor-native-crashes")) {
mMonitorNativeCrashes = true;
} else if (opt.equals("--ignore-native-crashes")) {
mIgnoreNativeCrashes = true;
} else if (opt.equals("--kill-process-after-error")) {
mKillProcessAfterError = true;
} else if (opt.equals("--hprof")) {
mGenerateHprof = true;
} else if (opt.equals("--pct-touch")) {
int i = MonkeySourceRandom.FACTOR_TOUCH;
mFactors[i] = -nextOptionLong("touch events percentage");
} else if (opt.equals("--pct-motion")) {
int i = MonkeySourceRandom.FACTOR_MOTION;
mFactors[i] = -nextOptionLong("motion events percentage");
} else if (opt.equals("--pct-trackball")) {
int i = MonkeySourceRandom.FACTOR_TRACKBALL;
mFactors[i] = -nextOptionLong("trackball events percentage");
} else if (opt.equals("--pct-rotation")) {
int i = MonkeySourceRandom.FACTOR_ROTATION;
mFactors[i] = -nextOptionLong("screen rotation events percentage");
} else if (opt.equals("--pct-syskeys")) {
int i = MonkeySourceRandom.FACTOR_SYSOPS;
mFactors[i] = -nextOptionLong("system (key) operations percentage");
} else if (opt.equals("--pct-nav")) {
int i = MonkeySourceRandom.FACTOR_NAV;
mFactors[i] = -nextOptionLong("nav events percentage");
} else if (opt.equals("--pct-majornav")) {
int i = MonkeySourceRandom.FACTOR_MAJORNAV;
mFactors[i] = -nextOptionLong("major nav events percentage");
} else if (opt.equals("--pct-appswitch")) {
int i = MonkeySourceRandom.FACTOR_APPSWITCH;
mFactors[i] = -nextOptionLong("app switch events percentage");
} else if (opt.equals("--pct-flip")) {
int i = MonkeySourceRandom.FACTOR_FLIP;
mFactors[i] = -nextOptionLong("keyboard flip percentage");
} else if (opt.equals("--pct-anyevent")) {
int i = MonkeySourceRandom.FACTOR_ANYTHING;
mFactors[i] = -nextOptionLong("any events percentage");
} else if (opt.equals("--pct-pinchzoom")) {
int i = MonkeySourceRandom.FACTOR_PINCHZOOM;
mFactors[i] = -nextOptionLong("pinch zoom events percentage");
} else if (opt.equals("--pkg-blacklist-file")) {
mPkgBlacklistFile = nextOptionData();
} else if (opt.equals("--pkg-whitelist-file")) {
mPkgWhitelistFile = nextOptionData();
} else if (opt.equals("--throttle")) {
mThrottle = nextOptionLong("delay (in milliseconds) to wait between events");
} else if (opt.equals("--randomize-throttle")) {
mRandomizeThrottle = true;
} else if (opt.equals("--wait-dbg")) {
// do nothing - it's caught at the very start of run()
} else if (opt.equals("--dbg-no-events")) {
mSendNoEvents = true;
} else if (opt.equals("--port")) {
mServerPort = (int) nextOptionLong("Server port to listen on for commands");
} else if (opt.equals("--setup")) {
mSetupFileName = nextOptionData();
} else if (opt.equals("-f")) {
mScriptFileNames.add(nextOptionData());
} else if (opt.equals("--profile-wait")) {
mProfileWaitTime = nextOptionLong("Profile delay" +
" (in milliseconds) to wait between user action");
} else if (opt.equals("--device-sleep-time")) {
mDeviceSleepTime = nextOptionLong("Device sleep time" +
"(in milliseconds)");
} else if (opt.equals("--randomize-script")) {
mRandomizeScript = true;
} else if (opt.equals("--script-log")) {
mScriptLog = true;
} else if (opt.equals("--bugreport")) {
mRequestBugreport = true;
} else if (opt.equals("--periodic-bugreport")){
mGetPeriodicBugreport = true;
mBugreportFrequency = nextOptionLong("Number of iterations");
} else if (opt.equals("-h")) {
showUsage();
return false;
} else {
System.err.println("** Error: Unknown option: " + opt);
showUsage();
return false;
}
}
} catch (RuntimeException ex) {
System.err.println("** Error: " + ex.toString());
showUsage();
return false;
}
// If a server port hasn't been specified, we need to specify
// a count
if (mServerPort == -1) {
String countStr = nextArg();
if (countStr == null) {
System.err.println("** Error: Count not specified");
showUsage();
return false;
}
try {
mCount = Integer.parseInt(countStr);
} catch (NumberFormatException e) {
System.err.println("** Error: Count is not a number");
showUsage();
return false;
}
}
return true;
}
根据命令行参数初始化对应各个参数
4、初始化系统接口
调用getSystemInterfaces初始化系统接口
private boolean getSystemInterfaces() {
mAm = ActivityManagerNative.getDefault();
if (mAm == null) {
System.err.println("** Error: Unable to connect to activity manager; is the system "
+ "running?");
return false;
}
mWm = IWindowManager.Stub.asInterface(ServiceManager.getService("window"));
if (mWm == null) {
System.err.println("** Error: Unable to connect to window manager; is the system "
+ "running?");
return false;
}
mPm = IPackageManager.Stub.asInterface(ServiceManager.getService("package"));
if (mPm == null) {
System.err.println("** Error: Unable to connect to package manager; is the system "
+ "running?");
return false;
}
try {
mAm.setActivityController(new ActivityController());
mNetworkMonitor.register(mAm);
} catch (RemoteException e) {
System.err.println("** Failed talking with activity manager!");
return false;
}
return true;
}
主要初始化IActivityManager、IWindowManager、IPackageManager三个接口，还有添加监控和注册广播
mAm.setActivityController(new ActivityController());
private class ActivityController extends IActivityController.Stub {
public boolean activityStarting(Intent intent, String pkg) {
boolean allow = checkEnteringPackage(pkg) || (DEBUG_ALLOW_ANY_STARTS != 0);
if (mVerbose > 0) {
// StrictMode's disk checks end up catching this on
// userdebug/eng builds due to PrintStream going to a
// FileOutputStream in the end (perhaps only when
// redirected to a file?) So we allow disk writes
// around this region for the monkey to minimize
// harmless dropbox uploads from monkeys.
StrictMode.ThreadPolicy savedPolicy = StrictMode.allowThreadDiskWrites();
System.out.println(" // " + (allow ? "Allowing" : "Rejecting") + " start of "
+ intent + " in package " + pkg);
StrictMode.setThreadPolicy(savedPolicy);
}
currentPackage = pkg;
currentIntent = intent;
return allow;
}
public boolean activityResuming(String pkg) {
StrictMode.ThreadPolicy savedPolicy = StrictMode.allowThreadDiskWrites();
System.out.println(" // activityResuming(" + pkg + ")");
boolean allow = checkEnteringPackage(pkg) || (DEBUG_ALLOW_ANY_RESTARTS != 0);
if (!allow) {
if (mVerbose > 0) {
System.out.println(" // " + (allow ? "Allowing" : "Rejecting")
+ " resume of package " + pkg);
}
}
currentPackage = pkg;
StrictMode.setThreadPolicy(savedPolicy);
return allow;
}
public boolean appCrashed(String processName, int pid,
String shortMsg, String longMsg,
long timeMillis, String stackTrace) {
StrictMode.ThreadPolicy savedPolicy = StrictMode.allowThreadDiskWrites();
System.err.println("// CRASH: " + processName + " (pid " + pid + ")");
System.err.println("// Short Msg: " + shortMsg);
System.err.println("// Long Msg: " + longMsg);
System.err.println("// Build Label: " + Build.FINGERPRINT);
System.err.println("// Build Changelist: " + Build.VERSION.INCREMENTAL);
System.err.println("// Build Time: " + Build.TIME);
System.err.println("// " + stackTrace.replace("\n", "\n// "));
StrictMode.setThreadPolicy(savedPolicy);
if (!mIgnoreCrashes || mRequestBugreport) {
synchronized (Monkey.this) {
if (!mIgnoreCrashes) {
mAbort = true;
}
if (mRequestBugreport){
mRequestAppCrashBugreport = true;
mReportProcessName = processName;
}
}
return !mKillProcessAfterError;
}
return false;
}
public int appEarlyNotResponding(String processName, int pid, String annotation) {
return 0;
}
public int appNotResponding(String processName, int pid, String processStats) {
StrictMode.ThreadPolicy savedPolicy = StrictMode.allowThreadDiskWrites();
System.err.println("// NOT RESPONDING: " + processName + " (pid " + pid + ")");
System.err.println(processStats);
StrictMode.setThreadPolicy(savedPolicy);
synchronized (Monkey.this) {
mRequestAnrTraces = true;
mRequestDumpsysMemInfo = true;
mRequestProcRank = true;
if (mRequestBugreport){
mRequestAnrBugreport = true;
mReportProcessName = processName;
}
}
if (!mIgnoreTimeouts) {
synchronized (Monkey.this) {
mAbort = true;
}
}
return (mKillProcessAfterError) ? -1 : 1;
}
}
public void register(IActivityManager am) throws RemoteException {
if (LDEBUG) System.out.println("registering Receiver");
am.registerReceiver(null, null, this, filter, null, UserHandle.USER_ALL);
}
public void performReceive(Intent intent, int resultCode, String data, Bundle extras,
boolean ordered, boolean sticky, int sendingUser) throws RemoteException {
NetworkInfo ni = (NetworkInfo) intent.getParcelableExtra(
ConnectivityManager.EXTRA_NETWORK_INFO);
if (LDEBUG) System.out.println("Network state changed: "
+ "type=" + ni.getType() + ", state=" + ni.getState());
updateNetworkStats();
if (NetworkInfo.State.CONNECTED == ni.getState()) {
if (LDEBUG) System.out.println("Network connected");
mLastNetworkType = ni.getType();
} else if (NetworkInfo.State.DISCONNECTED == ni.getState()) {
if (LDEBUG) System.out.println("Network not connected");
mLastNetworkType = -1; // unknown since we're disconnected
}
mEventTime = SystemClock.elapsedRealtime();
}
- 添加对activity的监控
- 添加对网络的监控
5、初始化事件源
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();
}
事件源代表测试数据的事件是从哪里过来的，不同的event source会有不同的类来做相应的实现：
- MonkeySourceNetwork.java: 事件是从网络如monkeyrunner过来的，处理的是界面控制操作事件
- MonkeySourceNetworkVars.java: 事件也是从网络如monkeyrunner过来的，处理的是getPropery事件
- MonkeySourceNetworkViews.java:事件也是从网络如monkeyrunner过来的，处理的是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
6、执行事件
调用runMonkeyCycles方法循环执行事件
把命令翻译成monkey事件然后放到命令队列EventQueue
以monkey自身随机事件源为例
... ((MonkeySourceRandom) mEventSource).generateActivity();
public void generateActivity() {
MonkeyActivityEvent e = new MonkeyActivityEvent(mMainApps.get(
mRandom.nextInt(mMainApps.size())));
mQ.addLast(e);
}
首先在初始化事件源时，会初始化一个MonkeyActivityEvent事件添加到EventQueue
MonkeyEvent ev = mEventSource.getNextEvent();
public MonkeyEvent getNextEvent() {
if (mQ.isEmpty()) {
generateEvents();
}
mEventCount++;
MonkeyEvent e = mQ.getFirst();
mQ.removeFirst();
return e;
}
private void generateEvents() {
float cls = mRandom.nextFloat();
int lastKey = 0;
if (cls < mFactors[FACTOR_TOUCH]) {
generatePointerEvent(mRandom, GESTURE_TAP);
return;
} else if (cls < mFactors[FACTOR_MOTION]) {
generatePointerEvent(mRandom, GESTURE_DRAG);
return;
} else if (cls < mFactors[FACTOR_PINCHZOOM]) {
generatePointerEvent(mRandom, GESTURE_PINCH_OR_ZOOM);
return;
} else if (cls < mFactors[FACTOR_TRACKBALL]) {
generateTrackballEvent(mRandom);
return;
} else if (cls < mFactors[FACTOR_ROTATION]) {
generateRotationEvent(mRandom);
return;
}
// The remaining event categories are injected as key events
for (;;) {
if (cls < mFactors[FACTOR_NAV]) {
lastKey = NAV_KEYS[mRandom.nextInt(NAV_KEYS.length)];
} else if (cls < mFactors[FACTOR_MAJORNAV]) {
lastKey = MAJOR_NAV_KEYS[mRandom.nextInt(MAJOR_NAV_KEYS.length)];
} else if (cls < mFactors[FACTOR_SYSOPS]) {
lastKey = SYS_KEYS[mRandom.nextInt(SYS_KEYS.length)];
} else if (cls < mFactors[FACTOR_APPSWITCH]) {
MonkeyActivityEvent e = new MonkeyActivityEvent(mMainApps.get(
mRandom.nextInt(mMainApps.size())));
mQ.addLast(e);
return;
} else if (cls < mFactors[FACTOR_FLIP]) {
MonkeyFlipEvent e = new MonkeyFlipEvent(mKeyboardOpen);
mKeyboardOpen = !mKeyboardOpen;
mQ.addLast(e);
return;
} else {
lastKey = 1 + mRandom.nextInt(KeyEvent.getMaxKeyCode() - 1);
}
if (lastKey != KeyEvent.KEYCODE_POWER
&& lastKey != KeyEvent.KEYCODE_ENDCALL
&& PHYSICAL_KEY_EXISTS[lastKey]) {
break;
}
}
MonkeyKeyEvent e = new MonkeyKeyEvent(KeyEvent.ACTION_DOWN, lastKey);
mQ.addLast(e);
e = new MonkeyKeyEvent(KeyEvent.ACTION_UP, lastKey);
mQ.addLast(e);
}
循环到EventQueue获取事件并执行，如果为空的话，就随机生成事件并添加到EventQueue中
事件执行完毕就从EventQueue中删除
3、执行事件通过事件注入方式执行，MonkeyEvent实现类都实现了父类的injectEvent方法
