如何从Java程序创建和运行Apache JMeter测试脚本？

我想使用Apache

JMeter提供的API从Java程序创建和运行测试脚本。我了解ThreadGroup和Samplers的基础知识。我可以使用JMeter

API在Java类中创建它们。

ThreadGroup threadGroup = new ThreadGroup();
    LoopController lc = new LoopController();
    lc.setLoops(5);
    lc.setContinueForever(true);
    threadGroup.setSamplerController(lc);
    threadGroup.setNumThreads(5);
    threadGroup.setRampUp(1);
HTTPSampler sampler = new HTTPSampler();
    sampler.setDomain("localhost");
    sampler.setPort(8080);
    sampler.setPath("/jpetstore/shop/viewCategory.shtml");
    sampler.setMethod("GET");
    Arguments arg = new Arguments();
    arg.addArgument("categoryId", "FISH");
    sampler.setArguments(arg);

但是，我对如何创建将线程组和采样器结合在一起的测试脚本然后从同一程序执行该脚本一无所知。有任何想法吗？

回答：

如果我理解正确，则希望从Java程序中以编程方式运行整个测试计划。就个人而言，我发现创建测试计划.JMX文件并以JMeter非GUI模式运行它更容易:)

这是一个基于原始问题中使用的控制器和采样器的简单Java示例。

import org.apache.jmeter.control.LoopController;
import org.apache.jmeter.engine.StandardJMeterEngine;
import org.apache.jmeter.protocol.http.sampler.HTTPSampler;
import org.apache.jmeter.testelement.TestElement;
import org.apache.jmeter.testelement.TestPlan;
import org.apache.jmeter.threads.SetupThreadGroup;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;
public class JMeterTestFromCode {
    public static void main(String[] args){
        // Engine
        StandardJMeterEngine jm = new StandardJMeterEngine();
        // jmeter.properties
        JMeterUtils.loadJMeterProperties("c:/tmp/jmeter.properties");
        HashTree hashTree = new HashTree();
        // HTTP Sampler
        HTTPSampler httpSampler = new HTTPSampler();
        httpSampler.setDomain("www.google.com");
        httpSampler.setPort(80);
        httpSampler.setPath("/");
        httpSampler.setMethod("GET");
        // Loop Controller
        TestElement loopCtrl = new LoopController();
        ((LoopController)loopCtrl).setLoops(1);
        ((LoopController)loopCtrl).addTestElement(httpSampler);
        ((LoopController)loopCtrl).setFirst(true);
        // Thread Group
        SetupThreadGroup threadGroup = new SetupThreadGroup();
        threadGroup.setNumThreads(1);
        threadGroup.setRampUp(1);
        threadGroup.setSamplerController((LoopController)loopCtrl);
        // Test plan
        TestPlan testPlan = new TestPlan("MY TEST PLAN");
        hashTree.add("testPlan", testPlan);
        hashTree.add("loopCtrl", loopCtrl);
        hashTree.add("threadGroup", threadGroup);
        hashTree.add("httpSampler", httpSampler);
        jm.configure(hashTree);
        jm.run();
    }
}
