在Ant中调用FlexUnit，完成对Flex(AS)代码的测试。
      在http://weblogs.macromedia.com/pmartin/archives/2006/06/flexunit_ant.html中，Peter Martin已经为我们提供了FlexUnit的包以及例子
但是下载下来发现用不了,修改如下：
  
      1. 导入下载的工程FlexUnitExample，将FlexAntTasks.jar拷贝到ClassPath中，然后修改build.properties文件，增加basedir="."，修改
flex.unit.swf="${basedir}/bin/AntTestRunner.swf"
basedir="."
# General properties
output.dir=${basedir}/dist

# Compile properties
#flex.sdk.home=C:/apps/adobe/flex2.0/sdk
flex.sdk.home=D:/Dev/Adobe/Flex Builder 3/sdks/3.0.0
application=AntTestRunner.mxml
mxmlc.args=-file-specs ${application} -library-path+=lib -output ${flex.unit.swf}

# Test properties
#flex.unit.swf=${output.dir}/AntTestRunner.swf
flex.unit.swf=${basedir}/bin/AntTestRunner.swf
report.dir=${basedir}/report

  2.修改build.xml

<project name="FlexUnitExample" default="main">
        
    <!-- Load the custom task definitions. -->
    <taskdef
        resource="com/adobe/ac/ant/tasks/tasks.properties" />

    <!--
    <taskdef
        resource="com/adobe/ac/ant/tasks/tasks.properties"
        classpath="${basedir}/FlexAntTasks.jar"/>
    -->
    
    <!-- Load the properties file. -->
    <property file="build.properties" />
    
    <target name="main" depends="compile, test" />
    
    <target name="compile">
        <exec
            dir="${basedir}"
            executable="${flex.sdk.home}/bin/mxmlc.exe"
            os="Windows XP"
            failonerror="false">
                            
            <arg line="${mxmlc.args}" />
        </exec>
        
        <exec
            dir="${basedir}"
            executable="${flex.sdk.home}/bin/mxmlc"
            os="Linux"
            failonerror="false">
                                    
            <arg line="${mxmlc.args}" />
        </exec>
    </target>
    
    <target name="test">                        
        <flexunit
            timeout="0"
            swf="${flex.unit.swf}"
            toDir="${report.dir}"
            haltonfailure="false" />
                
        <junitreport todir="${report.dir}">
            <fileset dir="${report.dir}">
                <include name="TEST-*.xml"/>
              </fileset>
                
              <report format="frames" todir="${report.dir}/html"/>
        </junitreport>
    </target>
</project>
  
    3. 运行ant，就可以了，还是很方便的。
