Monkeyrunner腳本的錄製與回放

　　繼上一篇monkeyrunner環境搭建：http://www.cnblogs.com/zh-ya-jing/p/4351245.html 以後，咱們能夠進一步學習monkeyrunner了。

　　我也是剛接觸monkeyrunner不久，對monkeyrunner的腳本錄製功能很感興趣，因此學習一下。沒想到中間遇到不少問題，以前是錄製腳本不經過，再以後是手機鏈接不上，monkeyrunner運行不起來，歸根結底仍是錄製腳本的問題，後向大神請教，可算是能成功錄製腳本了。

　　不知道出於什麼目的，google把monkeyrunner的腳本錄製功能雪藏了，須要從Android源碼中才能將其發掘出來。monkey_recorder.py是用來錄製在設備上的操做病生成腳本的，monkey_playback.py則用來回放腳本。

　　新建monkey_recorder.py文件，代碼以下：

#!/usr/bin/env monkeyrunner

from com.android.monkeyrunner import MonkeyRunner as mr
from com.android.monkeyrunner.recorder import MonkeyRecorder as recorder

device = mr.waitForConnection()
recorder.start(device)

　　新建monkey_playback.py文件，代碼以下：

#!/usr/bin/env monkeyrunner
# Copyright 2010, The Android Open Source Project
#
# Licensed under the Apache License, Version 2.0 (the "License");
# you may not use this file except in compliance with the License.

import sys
from com.android.monkeyrunner import MonkeyRunner

# The format of the file we are parsing is very carfeully constructed.
# Each line corresponds to a single command.  The line is split into 2
# parts with a | character.  Text to the left of the pipe denotes
# which command to run.  The text to the right of the pipe is a python
# dictionary (it can be evaled into existence) that specifies the
# arguments for the command.  In most cases, this directly maps to the
# keyword argument dictionary that could be passed to the underlying
# command. 

# Lookup table to map command strings to functions that implement that
# command.
CMD_MAP = {
    'TOUCH': lambda dev, arg: dev.touch(**arg),
    'DRAG': lambda dev, arg: dev.drag(**arg),
    'PRESS': lambda dev, arg: dev.press(**arg),
    'TYPE': lambda dev, arg: dev.type(**arg),
    'WAIT': lambda dev, arg: MonkeyRunner.sleep(**arg)
    }

# Process a single file for the specified device.
def process_file(fp, device):
    for line in fp:
        (cmd, rest) = line.split('|')
        try:
            # Parse the pydict
            rest = eval(rest)
        except:
            print 'unable to parse options'
            continue

        if cmd not in CMD_MAP:
            print 'unknown command: ' + cmd
            continue

        CMD_MAP[cmd](device, rest)


def main():
    file = sys.argv[1]
    fp = open(file, 'r')
    device = MonkeyRunner.waitForConnection()
    
    process_file(fp, device)
    fp.close();
    

if __name__ == '__main__':
    main()

　　鏈接真機或模擬器，執行如下命令：

$monkeyrunner monkey_recorder.py

執行完畢以後，monkeyrunner會打開一個窗口，以下所示。

它會不停地從設備上抓取最新界面，你能夠直接在左邊的屏幕截圖上單擊圖標來模擬觸控操做方式，不要直接操做真機或模擬器，不然沒法錄製腳本。操做的同時右邊會實時顯示錄製的腳本，單擊「Type something」按鈕輸入字符串，單擊「Fling」按鈕模擬滑動手勢。當操做錄製完畢後，單擊「Export Actions」按鈕，將腳本保存到指定目錄，好比test.mr，關閉monkeyrunner運行窗口。

　　將錄製好的腳本傳給monkey_playback.py文件就能夠回放了，執行以下命令:

$monkeyrunner monkey_playback.py test.mr

假如回放過程出錯，有多是真機或者模擬器反應比較慢，兩次操做之間間隔時間過短，因此建議兩次操做之間加些wait，即每次操做以後點擊「wait」按鈕，增長等待時間。

必須把monkey_recorder.py，monkey_playback.py和錄製的腳本test.mr放入"*\adt-bundle-windows-x86-20130917\sdk\tools"目錄下，並且運行.py文件都使用絕對路徑。
