Ant+Jmeter自动化接口测试

Ant驱动Jmeter
单独使用Jmeter来执行接口测试是非常简单的了，使用Ant来驱动Jmeter就需要些一个构建文件build.xml

<project name="Ant-Jmeter-Test" default="all" basedir=".">
    <tstamp>
        <format property="time" pattern="yyyyMMddhhmm" />
    tstamp>
    
    <property name="jmeter.home" value="/Users/gengmei/Downloads/apache-jmeter-3.0" />
    
    <property name="jmeter.result.jtl.dir" value="/Users/gengmei/Downloads/jmeterTest/resultLog/jtl" />
    
    <property name="jmeter.result.html.dir" value="/Users/gengmei/Downloads/jmeterTest/resultLog/html" />
    
    <property name="ReportName" value="TestReport" />
    <property name="jmeter.result.jtlName" value="${jmeter.result.jtl.dir}/${ReportName}${time}.jtl" />
    <property name="jmeter.result.htmlName" value="${jmeter.result.html.dir}/${ReportName}${time}.html" />
    
    <property name="mail_to" value="[email protected]" />
    
    <property name="ComputerName" value="172.30.9.158" />
    <target name="all">
        <antcall target="test" />
        <antcall target="report" />
    target>
    <target name="test">
        <taskdef name="jmeter" classname="org.programmerplanet.ant.taskdefs.jmeter.JMeterTask" />
        <jmeter jmeterhome="${jmeter.home}" resultlog="${jmeter.result.jtlName}">
            
            <testplans dir="/Users/gengmei/Downloads/jmeterTest/script" includes="*.jmx" />
        jmeter>
    target>
    <target name="report">
        <xslt in="${jmeter.result.jtlName}" out="${jmeter.result.htmlName}" style="${jmeter.home}/extras/jmeter-results-detail-report_21.xsl" />
        
        <copy todir="${jmeter.result.html.dir}">
            <fileset dir="${jmeter.home}/extras">
                <include name="collapse.png" />
                <include name="expand.png" />

只要Ant配置好，直接运行Ant就行了。结果如下：

几个大坑

taskdef class org.programmerplanet.ant.taskdefs.jmeter.JMeterTask cannot be found
using the classloader AntClassLoader[]

这个报错非常坑爹，是由于Ant有一个ant-jmeter-1.1.1.jar这个文件缺失了，所以一直会报这个错。

stylesheet /Users/SvenWeng/apache-jmeter-3.0/extras/jmeter-results-detail-report_21.xsl doesn't exist.
这个报错是由于我使用的是Jmeter3.0。而3.0文件下面的对应文件是jmeter-results-detail-report.xsl 所以报了这个错，但是这个文件是有问题的.

解决办法：
1，下载Jmeter2.*的文件包
2，找到红框中的文件复制到jmeter3.0对应的文件夹中
测试报告中三个指标为NaN
这个问题也是一个坑，我找了好久才找到原因。

需要从Jmeter的lib包里把xalan-2.7.2.jar和serializer-2.7.2.jar copy到Ant的lib包里。
