继上篇Blog,本篇将重点介绍利用Maven并开发插件解析Jmeter生成的报告,于是就有Jmeter-analysis-maven-plugin这个插件,这个插件是由Aren Franka开发的,但是当你使用这个插件的时候会发现,它只能解析Http request请求的报告,不能解析如Webservice request请求的报告以及其他请求的报告,这是由于这个插件的代码中存在一个bug,于是自己动手修改了这个bug,因为通过Nongui生成的Jmeter报告是以.jtl结尾的类似于xml的文件,因此在Jmeter-analysis-maven-plugin这个插件中会采用SAX来解析报告文件。具体来看一下Jmeter报告文件的格式:
<?xml version="1.0" encoding="UTF-8"?> <testResults version="1.2"> <sample t="49" lt="0" ts="1339404299860" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-1" dt="text" by="713"/> <sample t="45" lt="0" ts="1339404301064" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-13" dt="text" by="713"/> <sample t="45" lt="0" ts="1339404301166" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-14" dt="text" by="713"/> <sample t="53" lt="0" ts="1339404301266" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-15" dt="text" by="713"/> <sample t="49" lt="0" ts="1339404301362" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-16" dt="text" by="713"/> <sample t="129" lt="0" ts="1339404301465" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-17" dt="text" by="713"/> <sample t="51" lt="0" ts="1339404301564" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-18" dt="text" by="713"/> <sample t="55" lt="0" ts="1339404301665" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-19" dt="text" by="713"/> <sample t="53" lt="0" ts="1339404301764" s="true" lb="PoscPaymentServiceImplService" rc="200" rm="OK" tn="posc 1-20" dt="text" by="713"/> </testResults>
这是一个webservice请求所得到的测试结果,所以每个请求都是以sample开始的,如果是http请求的话,会以httpsample开始,大家可以在我的代码中看到我用了一个hashset将这两种element都放在里面,然后通过判断是否存在相关的element来解析报告,原代码中只考虑了http这种情况,不过我已经email给aren,他已经修复了这个bug。下面我们具体看一下每个属性的含义,其中ts表示每个样本结束的Timestamp,s表示请求的状态,成功为true,失败为false,lb表示请求的名称,rc表示请求的response code, rm表示response message,tn表示thread name,dt表示data type, dy表示data byte。通过解析这个xml文本我们可以生成这样一个请求结果:
通过解析可以得到response time, tps等,还可以生成图表如下所示:
这个可以看到是请求的表现图。
Aren在开发Jmeter-analysis-maven-plugin这个插件的时候已经提供了,生成html,cvs, chart几种方式,我在代码中增加了一种方式就是将测试结果存入数据库。
具体大家可以看我后续在github上上传的代码。Aren在开发该插件的时候没有将Tps, VUser这些数据放在报告中,我也在代码中做了一些修改来展示这些数据。
总而言之使用这个插件可以很方便的来进行性能测试,我们只需要将上一篇blog所提到的关于Jmeter-maven-plugin结合本篇文章所提到的Jmeter-analysis-maven-plugin结合起来使用便可以方便的构建各种测试场景,我们只需要在pom.xml中进行如下配置:

便可以完成一个测试场景,关于具体每一个element,这里不做详细解释,因为在注解中已经写的很详细了。关于如何配合CI构建云测试平台将在下一篇blog中继续阐述。
