使用ant運行Monkeyrunner測試

注：本文在windows 7下實現，linux用戶請自行參考相關路徑自行修改

1. 瞭解monkeyrunner運行機制

2. 配置build.xml

用到的路徑

------------------------------------------------

ANDROID_HOME = "your android sdk path"

JAVA_EXT_DIRS = "java.ext.dirs"的值

-------------------------------------------------

1. 瞭解monkeyrunner運行機制

打開%ANDROID_HOME%\tools\monkeyrunner.bat

內容如下

setlocal

rem Set up prog to be the path of this script, including following symlinks,
rem and set up progdir to be the fully-qualified pathname of its directory.
set prog=%~f0

rem Change current directory and drive to where the script is, to avoid
rem issues with directories containing whitespaces.
cd /d %~dp0

rem Check we have a valid Java.exe in the path.
set java_exe=
call lib\find_java.bat
if not defined java_exe goto :EOF

set jarfile=monkeyrunner.jar
set frameworkdir=
set libdir=

if exist %frameworkdir%%jarfile% goto JarFileOk
    set frameworkdir=lib\

if exist %frameworkdir%%jarfile% goto JarFileOk
    set frameworkdir=..\framework\

:JarFileOk

set jarpath=%frameworkdir%%jarfile%

if not defined ANDROID_SWT goto QueryArch
    set swt_path=%ANDROID_SWT%
    goto SwtDone

:QueryArch

    for /f %%a in ('%java_exe% -jar %frameworkdir%archquery.jar') do set swt_path=%frameworkdir%%%a

:SwtDone

if exist %swt_path% goto SetPath
    echo SWT folder '%swt_path%' does not exist.
    echo Please set ANDROID_SWT to point to the folder containing swt.jar for your platform.
    exit /B

:SetPath

call %java_exe% -Xmx512m -Djava.ext.dirs=%frameworkdir%;%swt_path% -Dcom.android.monkeyrunner.bindir=..\framework -jar %jarpath% %*

最後整理出來如下內容

frameworkdir = %ANDROID_HOME%\tools\lib

架構類型 arch = java -jar %frameworkdir%\archquery.jar

swt_path = %frameworkdir%\%arch%

jarpath = value=%frameworkdir%\monkeyrunner.jar

%* = monkeyrunner的腳本文件（*.py 或者*.jy)

[windows下不存在framework文件夾，可以忽略]

使用如下命令則可以運行Monkeyrunner交互界面

java -Xmx512m -Djava.ext.dirs=%frameworkdir%;%swt_path%  -jar %jarpath%

使用如下命令則可以運行Monkeyrunner腳本

java -Xmx512m -Djava.ext.dirs=%frameworkdir%;%swt_path%  -jar %jarpath% demo.py

接下來，我們開始寫build.xml文件

2. 配置build.xml

創建一個build.xml文件

內容如下

<?xml version="1.0" encoding="UTF-8"?>

<project name="MonkeyRunnerTest" default="compile">
  <property name="src.dir" value="src"/>
  <property name="android.home" value="D:\APP\android-sdk-windows"/>
  <property name="frameworkdir" value="${android.home}\tools\lib"/>
  <property name="swt_path" value="${frameworkdir}\x86"/>
  <property name="jarpath" value="${frameworkdir}\monkeyrunner.jar"/>
  <property name="demo" value="${src.dir}\demo.py"/>

  <target name="runtest">
      <java jar="${jarpath}"
          maxmemory="512m"
          fork="true"
          >
          <arg file="${demo}"/>
      </java>
  </target>
</project>

解釋下

我們再看下monkeyrunner運行需要用到的java參數

java -Xmx512m -Djava.ext.dirs=%frameworkdir%;%swt_path%  -jar %jarpath%

maxmemory="512m" 代表-Xmx512m

jar="${jarpath}" 代表 -jar %jarpath%

arg file="${demo}" 代表 咱們要用到的腳本文件

[注意]

對於-Djava.ext.dirs=%frameworkdir%;%swt_path%，無法在ant內部進行修改，因爲java.ext.dirs比較特殊，不允許動態加載。這裏請參考如下文章

http://blog.csdn.net/coolriver/article/details/315206

http://java.chinaitlab.com/base/848761_3.html

當沒有辦法的情況下，只能使用最笨的辦法：把%frameworkdir%;%swt_path%這兩個目錄下的文件拷貝到java.ext.dirs目錄下

副作用：這樣會導致android project的ant無法正常使用，所以請備份目錄下原來的文件，以備不時之需

在ant中可以使用<echo message="java.ext.dirs : ${java.ext.dirs}"/>來打印路徑

------------------------------------------------------------------------------------------------

最後，運行ant runtest.

結果如下：

runtest:
