从Java代码调用Jmeter函数时不执行 [英] Jmeter functions don't executing when calling from java code

问题描述

我在jmx文件中使用了一些jmeter函数。
当我使用jmeter工具从命令行运行它时，它正常运行，执行函数并返回一个值。

当我运行java代码时，它加载相同的jmx文件，它将一个函数作为一个字符串并且不返回一个值。

我已经测试了几个函数，结果是一样的。
在jtl文件中，我看到类似这样的内容 - $ {__ time（yyyy-MM-dd HH：mm：ss）}

 < httpSample t =663it =0lt =631ts =1492989803759s =truelb =User-getapikey $ {__ time（yyyy-MM-dd HH：mm： ss）}rc =200rm =tn =线程组1-1dt =textde =UTF-8by =528ng =1na =1> ; 
  

它是我的java代码，当我没有函数时它正常工作：

  StandardJMeterEngine jmeter = new StandardJMeterEngine（）; 
 JMeterUtils.loadJMeterProperties（jmeterPropertiesPath）; 
 JMeterUtils.setJMeterHome（jmeterHomePath）; 
 JMeterUtils.initLogging（）; 
 JMeterUtils.initLocale（）; 
 
 SaveService.loadProperties（）; 
 HashTree testPlanTree = null; 
尝试{
 log.info（loading testPlanTree）; 
 testPlanTree = SaveService.loadTree（jmxFile）; 
 JMeter.convertSubTree（testPlanTree）; 
} catch（IOException ex）{
 log.info（将文件加载为树时出错）; 
 log.info（ex.getMessage（））; 
 return; 
} 
 jmeter.configure（testPlanTree）; 
 jmeter.run（）; 
  

解决方案

您的代码看起来不错，只需您的项目类路径中有 ApacheJMeter_functions.jar 。该文件位于JMeter安装的lib / ext文件夹下。

您可能还想添加

  Summariser summer = null; 
 String summariserName = JMeterUtils.getPropDefault（summariser.name，summary）; （sumriserName.length（）> 0）{
 summer = new Summariser（summariserName）; 
 if 
} 
 
 ResultCollector logger = new ResultCollector（summer）; 
 logger.setFilename（result.jtl）; 
 testPlanTree.add（testPlanTree.getArray（）[0]，logger）; 
  

查看

I'm using some jmeter functions in my jmx file. When I run it from command line with jmeter tool, its running normally, executing the function and return a value.

When I run the java code , which load the same jmx file its taking a function as a string and don't return a value.

I have tested with several functions, Results are the same. In jtl file I see something like this- ${__time(yyyy-MM-dd HH:mm:ss)}

<httpSample t="663" it="0" lt="631" ts="1492989803759" s="true" lb="User-getapikey   ${__time(yyyy-MM-dd HH:mm:ss)} " rc="200" rm="" tn="Thread Group 1-1" dt="text" de="UTF-8" by="528" ng="1" na="1">

Its my java code, its working normally when I don't have a functions:

StandardJMeterEngine jmeter = new StandardJMeterEngine();
JMeterUtils.loadJMeterProperties(jmeterPropertiesPath);
JMeterUtils.setJMeterHome(jmeterHomePath);
JMeterUtils.initLogging();
JMeterUtils.initLocale();

SaveService.loadProperties();
HashTree testPlanTree = null;
                try{
                    log.info("loading testPlanTree");
                    testPlanTree = SaveService.loadTree(jmxFile);
                    JMeter.convertSubTree( testPlanTree );
                }catch(IOException ex){
                    log.info("error loading file as tree");
                    log.info(ex.getMessage());
                    return;
                }
                jmeter.configure(testPlanTree);
                jmeter.run();

解决方案

Your code looks good, just double check you have ApacheJMeter_functions.jar in your project classpath. The file is located under "lib/ext" folder of your JMeter installation.

You might also want to add ResultCollector to store your test execution results into .jtl file like:

Summariser summer = null;
String summariserName = JMeterUtils.getPropDefault("summariser.name", "summary");
if (summariserName.length() > 0) {
    summer = new Summariser(summariserName);
}

ResultCollector logger = new ResultCollector(summer);
logger.setFilename("result.jtl");
testPlanTree.add(testPlanTree.getArray()[0], logger);
