所以我在我的Maven项目中使用这个例子：
public class JMeterFromScratch {
public static void main(String[] argv) throws Exception {
//JMeter Engine
StandardJMeterEngine jmeter = new StandardJMeterEngine();
//JMeter initialization (properties, log levels, locale, etc)
JMeterUtils.loadJMeterProperties("C:/git/jbehave-snbtracker/src/main/resources/config/jmeter.properties");
//JMeterUtils.initLogging();// you can comment this line out to see extra log messages of i.e. DEBUG level
JMeterUtils.initLocale();
// JMeter Test Plan
HashTree testPlanTree = new HashTree();
// HTTP Sampler
HTTPSampler httpSampler = new HTTPSampler();
httpSampler.setDomain("example.com");
httpSampler.setPort(80);
httpSampler.setPath("/");
httpSampler.setMethod("GET");
// Loop Controller
TestElement loopController = new LoopController();
((LoopController)loopController).setLoops(1);
loopController.addTestElement(httpSampler);
((LoopController)loopController).setFirst(true);
((LoopController)loopController).initialize();
// Thread Group
SetupThreadGroup threadGroup = new SetupThreadGroup();
threadGroup.setNumThreads(1);
threadGroup.setRampUp(1);
threadGroup.setSamplerController(((LoopController)loopController));
// Test Plan
TestPlan testPlan = new TestPlan("Create JMeter Script From Java Code");
// Construct Test Plan from previously initialized elements
testPlanTree.add("testPlan", testPlan);
testPlanTree.add("loopController", loopController);
testPlanTree.add("threadGroup", threadGroup);
testPlanTree.add("httpSampler", httpSampler);
// Run Test Plan
jmeter.configure(testPlanTree);
jmeter.run();
}
}
在其中我具有以下依赖性：
<dependency>
<groupId>org.apache.jmeter</groupId>
<artifactId>ApacheJMeter_core</artifactId>
<version>3.1</version>
</dependency>
<dependency>
<groupId>org.apache.jmeter</groupId>
<artifactId>ApacheJMeter_http</artifactId>
<version>2.13</version>
</dependency>
奇怪的是,在ThreadGroup类的makeThread()方法中,存在以下这一行：
JMeterThread jmeterThread = new JMeterThread(this.cloneTree(threadGroupTree), this, notifier);
对cloneTree的调用似乎确实克隆了树,但是LoopController中没有Sampler.因此,当JMeterThread到达此处时：
Sampler sampler = this.threadGroupLoopController.next(); // returns null
while(true) {
while(this.running && sampler != null) {
采样器为null,因此没有任何执行.
那我在做什么错？
谢谢.
解决方法:
>我不喜欢pom.xml中的版本不匹配,我相信您应该使用< version> 3.1< / version>对于两个组件
>我不喜欢您建立测试计划的方式,应该是这样的：
testPlanTree.add(testPlan);
HashTree threadGroupHashTree = testPlanTree.add(testPlan, threadGroup);
threadGroupHashTree.add(httpSampler);
>我认为您应该将日志记录添加到.jtl文件中,以便能够看到结果
