Android之自動化壓力測試工具:Monkey詳解
monkey 壓力測試
adb -d shell monkey -p your.package.name -v 6000
一、 什么是Monkey
Monkey是Android中的一個命令行工具,可以運行在模擬器里或實際設備中。它向系統發送偽隨機的用戶事件流(如按鍵輸入、觸摸屏輸入、手勢輸入等),實現對正在開發的應用程序進行壓力測試。Monkey測試是一種為了測試軟件的穩定性、健壯性的快速有效的方法。
二、 Monkey的特征
1、測試的對象僅為應用程序包,有一定的局限性。
2、 Monky測試使用的事件流數據流是隨機的,不能進行自定義。
3、可對MonkeyTest的對象,事件數量,類型,頻率等進行設置。
三、Monkey的基本用法
基本語法如下:
$ adb shell monkey [options]
如果不指定options,Monkey將以無反饋模式啟動,并把事件任意發送到安裝在目標環境中的全部包。下面是一個更為典型的命令行示例,它啟動指定的應用程序,并向其發送1500個偽隨機事件:
$ adb shell monkey -p your.package.name -v 1500
$ monkey -p(package的意思) 指定文件名 -v(測試的次數和頻率) number(次數)
四、Monkey測試的一個實例
通過這個實例,我們能理解Monkey測試的步驟以及如何知道哪些應用程序能夠用Monkey進行測試。
Windows下(注:2—4步是為了查看我們可以測試哪些應用程序包,可省略):
1、 通過eclipse啟動一個Android的emulator
2、 在命令行中輸入:adb devices查看設備連接情況
C:\Documents and Settings\Administrator>adb devices
List of devices attached
emulator-5554 device
3、 在有設備連接的前提下,在命令行中輸入:adb shell 進入shell界面
C:\Documents and Settings\Administrator>adb shell
#
4、 查看data/data文件夾下的應用程序包。注:我們能測試的應用程序包都在這個目錄下面
C:\Documents and Settings\Administrator>adb shell
# ls data/data
ls data/data
com.google.android.btrouter

com.android.providers.downloads
com.android.deskclock

5、 以com.android.camera作為對象進行MonkeyTest
#monkey -p com.android.camera -v 500
其中-p表示對象包 –v 表示事件數量
運行過程中,Emulator中的應用程序在不斷地切換畫面。
按照選定的不同級別的反饋信息,在Monkey中還可以看到其執行過程報告和生成的事件。
注:具體參數的設定可參考:

五、關于Monkey測試的停止條件
Monkey Test執行過程中在下列三種情況下會自動停止:
1、如果限定了Monkey運行在一個或幾個特定的包上,那么它會監測試圖轉到其它包的操作,并對其進行阻止。
2、如果應用程序崩潰或接收到任何失控異常,Monkey將停止并報錯。
3、如果應用程序產生了應用程序不響應(application not responding)的錯誤,Monkey將會停止并報錯。
通過多次并且不同設定下的Monkey測試才算它是一個穩定性足夠的程序。
下面是開發文檔的原文,對其他的命令也有詳細解釋::
http://developer.android.com/guide/developing/tools/monkey.html:
Basic Use of the Monkey
You can launch the Monkey using a command line on your development machine or from a script. Because the Monkey runs in the emulator/device environment, you must launch it from a shell in that environment. You can do this by prefacing adb shell to each command, or by entering the shell and entering Monkey commands directly.
The basic syntax is:
$ adb shell monkey [options] <event-count>
With no options specified, the Monkey will launch in a quiet (non-verbose) mode, and will send events to any (and all) packages installed on your target. Here is a more typical command line, which will launch your application and send 500 pseudo-random events to it:
$ adb shell monkey -p your.package.name -v 500
General --help Prints a simple usage guide.
-v
Each -v on the command line will increment the verbosity level. Level 0 (the default) provides little information beyond startup notification, test completion, and final results. Level 1 provides more details about the test as it runs, such as individual events being sent to your activities. Level 2 provides more detailed setup information such as activities selected or not selected for testing.
Events
-s <seed>
Seed value for pseudo-random number generator. If you re-run the Monkey with the same seed value, it will generate the same sequence of events.
--throttle <milliseconds>
Inserts a fixed delay between events. You can use this option to slow down the Monkey. If not specified, there is no delay and the events are generated as rapidly as possible.
--pct-touch <percent>
Adjust percentage of touch events. (Touch events are a down-up event in a single place on the screen.)
--pct-motion <percent>
Adjust percentage of motion events. (Motion events consist of a down event somewhere on the screen, a series of pseudo-random movements, and an up event.)
--pct-trackball <percent>
Adjust percentage of trackball events. (Trackball events consist of one or more random movements, sometimes followed by a click.)
--pct-nav <percent>
Adjust percentage of "basic" navigation events. (Navigation events consist of up/down/left/right, as input from a directional input device.)
--pct-majornav <percent>
Adjust percentage of "major" navigation events. (These are navigation events that will typically cause actions within your UI, such as the center button in a 5-way pad, the back key, or the menu key.)
--pct-syskeys <percent>
Adjust percentage of "system" key events. (These are keys that are generally reserved for use by the system, such as Home, Back, Start Call, End Call, or Volume controls.)
--pct-appswitch <percent>
Adjust percentage of activity launches. At random intervals, the Monkey will issue a startActivity() call, as a way of maximizing coverage of all activities within your package.
--pct-anyevent <percent>
Adjust percentage of other types of events. This is a catch-all for all other types of events such as keypresses, other less-used buttons on the device, and so forth.
Constraints
-p <allowed-package-name>
If you specify one or more packages this way, the Monkey will only allow the system to visit activities within those packages. If your application requires access to activities in other packages (e.g. to select a contact) you'll need to specify those packages as well. If you don't specify any packages, the Monkey will allow the system to launch activities in all packages. To specify multiple packages, use the -p option multiple times — one -p option per package.
-c <main-category>
If you specify one or more categories this way, the Monkey will only allow the system to visit activities that are listed with one of the specified categories. If you don't specify any categories, the Monkey will select activities listed with the category Intent.CATEGORY_LAUNCHER or Intent.CATEGORY_MONKEY. To specify multiple categories, use the -c option multiple times — one -c option per category.
Debugging
--dbg-no-events
When specified, the Monkey will perform the initial launch into a test activity, but will not generate any further events. For best results, combine with -v, one or more package constraints, and a non-zero throttle to keep the Monkey running for 30 seconds or more. This provides an environment in which you can monitor package transitions invoked by your application.
--hprof
If set, this option will generate profiling reports immediately before and after the Monkey event sequence. This will generate large (~5Mb) files in data/misc, so use with care. See Traceview for more information on trace files.
--ignore-crashes
Normally, the Monkey will stop when the application crashes or experiences any type of unhandled exception. If you specify this option, the Monkey will continue to send events to the system, until the count is completed.
--ignore-timeouts
Normally, the Monkey will stop when the application experiences any type of timeout error such as a "Application Not Responding" dialog. If you specify this option, the Monkey will continue to send events to the system, until the count is completed.
--ignore-security-exceptions
Normally, the Monkey will stop when the application experiences any type of permissions error, for example if it attempts to launch an activity that requires certain permissions. If you specify this option, the Monkey will continue to send events to the system, until the count is completed.
--kill-process-after-error
Normally, when the Monkey stops due to an error, the application that failed will be left running. When this option is set, it will signal the system to stop the process in which the error occurred. Note, under a normal (successful) completion, the launched process(es) are not stopped, and the device is simply left in the last state after the final event.
--monitor-native-crashes
Watches for and reports crashes occurring in the Android system native code. If --kill-process-after-error is set, the system will stop.
--wait-dbg Stops the Monkey from executing until a debugger is attached to it.
