java测试计划结构在JMeter UI（预期）和API（错误）之间变化

Question

我的测试计划在UI中是这样的

Test Plan
   Thread Group1
       Sampler 1
          header manager
          result collector
          bean shell post processor   
       Sampler 2
          bean shell pre processor
          header manager
          result collector
          bean shell post processor
   Thread Group2
       Bean shell pre processor
       Throughput 1
          Sampler 3
              header manager
              result collector
       Throughput 2
          Sampler 4
              bean shell pre processor
              header manager
              result collector
              bean shell post processor  
          Sampler 5
              header manager
              result collector
       Result Collector

在Java代码中，我尝试像这样添加采样器

ThroughputController throughput1 = new ThroughputController();
throughput1.setPercentThroughput(100.0f);

ThroughputController throughput2 = new ThroughputController();
throughput1.setPercentThroughput(0.0f);

TestPlan testPlan = new TestPlan();
testPlan.setSerialized(true);

HashTree throughputTree1 = new HashTree();
HashTree throughputTree2 = new HashTree();

HashTree testPlanTree = new HashTree();
HashTree threadGroupTree1 = new HashTree();

HashTree samplerTree1 = new HashTree(); 
samplerTree1.add(sampler1,resultCollector1);
samplerTree1.add(sampler1,header1); 

但输出测试计划树并不像预期的那样

我怎样才能像在UI中一样，按照上面提到的顺序获得测试计划

二,。测试计划树会随着Java版本的不同而变化吗

以下代码依赖于JMeter API：

import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.config.gui.ArgumentsPanel;
import org.apache.jmeter.control.LoopController;

public class JMeterFromCode {

    public static void main(String[] args) throws Exception {

        String jmeterHome = "/tmp/jmeter";

        JMeterUtils.setJMeterHome(jmeterHome);
        JMeterUtils.loadJMeterProperties(jmeterHome + "/bin/jmeter.properties");

        LoopController loopController = new LoopController();
        loopController.setLoops(1);

        threadGroup1.setRampUp(1);
        threadGroup1.setSamplerController(loopController);
        threadGroup1.setProperty(TestElement.TEST_CLASS, ThreadGroup.class.getName());
        threadGroup1.setProperty(TestElement.GUI_CLASS, ThreadGroupGui.class.getName());

        ThreadGroup threadGroup2 = new ThreadGroup();
        threadGroup2.setName("Thread Group 2");
        threadGroup2.setNumThreads(1);
        threadGroup2.setRampUp(1);
        threadGroup2.setSamplerController(loopController);
        threadGroup2.setProperty(TestElement.TEST_CLASS, ThreadGroup.class.getName());
        threadGroup2.setProperty(TestElement.GUI_CLASS, ThreadGroupGui.class.getName());

        ThroughputController throughputController1 = new ThroughputController();

        IntegerProperty style = new IntegerProperty();
        style.setName("ThroughputController.style");
        style.setValue(1);
        FloatProperty throughput1 = new FloatProperty();
        throughput1.setValue(100);
        throughputController1.setProperty(throughput1);
        throughputController1.setProperty(style);
        throughputController1.setProperty(TestElement.TEST_CLASS, ThroughputController.class.getName());
        throughputController1.setProperty(TestElement.GUI_CLASS, ThroughputControllerGui.class.getName());

        ThroughputController throughputController2 = new ThroughputController();

        SaveService.saveTree(testPlanTree, new FileOutputStream(jmeterHome + "/bin/example.jmx"));
    }
}

产生JMeter Test Plan类似：

这应该是你要找的东西

还要注意，有一种更简单的方法可以在不使用JMeter GUI的情况下创建JMeter测试计划，Taurus工具提供了使用简单的YAML语法创建和运行JMeter测试的可能性，有关详细信息，请参阅Taurus: A New Star in the Test Automation Tools Constellation文章
