JEMETER非GUI：缺少com类。思想工作。xstream。转换器。转换异常错误

Question

我正在从头开始创建JMeter测试计划。这是我的代码：

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

        StandardJMeterEngine jmeterEngine = new StandardJMeterEngine();
        JMeterUtils.setJMeterHome("/Users/myDir/Documents/JMeter/apache-jmeter-3.3");
        JMeterUtils.loadJMeterProperties("src/main/resources/jmeter.properties");
        JMeterUtils.initLocale();

        //create test plan
        TestPlan testPlan = new TestPlan();
        testPlan.setEnabled(true);
        testPlan.setName("Test Plan");

        //create thread group
        ThreadGroup threadGroup = new ThreadGroup();
        threadGroup.setNumThreads(1);
        threadGroup.setRampUp(1);

        // create http sampler
        HTTPSampler httpSampler = new HTTPSampler();
        httpSampler.setProtocol("https");
        httpSampler.setDomain("myDomain.services.company.com");
        httpSampler.setPath("ims/login/v1/token");
        httpSampler.setMethod("POST"); 
        httpSampler.setFollowRedirects(true);
        httpSampler.setAutoRedirects(false);
        httpSampler.setUseKeepAlive(true);
        httpSampler.addArgument("client_id", "argValue1");
        httpSampler.addArgument("scope", "argValue2");
        httpSampler.addArgument("userName", "abc%2B249%40gmail.com");
        httpSampler.addArgument("password", "Abc123"); 

        //Add sampler to the thread group
        threadGroup.addTestElement(httpSampler);

        HashTree testPlanHashTree = new HashTree();
        testPlanHashTree.add(testPlan);
        testPlanHashTree.add(threadGroup);

        // Generating the JMX file
        SaveService.saveTree(testPlanHashTree, new FileOutputStream(JMeterUtils.getJMeterHome() + "/bin/Test2.jmx"));
    }

当我执行这段代码时，我的Test2。jmx已经创建。

接下来，我尝试通过使用以下命令运行Test2.jmx通过Jmetm的非GUI模式：

杰米。sh-n-t测试2。jmx

Jmeter没有运行我的测试计划，而是抛出以下错误：

Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:'/Users/chandrat/Documents/JMeter/apache-jmeter-3.3/bin/Test2.jmx', missing class com.thoughtworks.xstream.converters.ConversionException:

line number         : 6
version             : 3.3 r1808647
-------------------------------

我不知道如何解决这个问题？原因-消息是空白的？我应该怎么做才能在没有上述错误的情况下执行我的测试计划？

2） 你能看看我的测试计划生成代码吗？那代码对吗？测试组应该直接添加到树中还是先添加到测试计划中，然后再将测试计划添加到树中？

以下是pom文件中的依赖项，以防我丢失一个jar。

请帮忙。谢谢

为了能够在JMeter GUI中打开生成的测试计划，您需要定义更多的属性，修改代码如下：

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

    StandardJMeterEngine jmeterEngine = new StandardJMeterEngine();
    JMeterUtils.setJMeterHome("/Users/myDir/Documents/JMeter/apache-jmeter-3.3");
    JMeterUtils.loadJMeterProperties("src/main/resources/jmeter.properties");
    JMeterUtils.initLocale();

    //create test plan
    TestPlan testPlan = new TestPlan();
    testPlan.setEnabled(true);
    testPlan.setName("Test Plan");
    testPlan.setProperty(TestElement.TEST_CLASS, TestPlan.class.getName());
    testPlan.setProperty(TestElement.GUI_CLASS, TestPlanGui.class.getName());
    testPlan.setUserDefinedVariables((Arguments) new ArgumentsPanel().createTestElement());

    LoopController loopController = new LoopController();
    loopController.setLoops(1);
    loopController.setFirst(true);
    loopController.setProperty(TestElement.TEST_CLASS, LoopController.class.getName());
    loopController.setProperty(TestElement.GUI_CLASS, LoopControlPanel.class.getName());
    loopController.initialize();

    //create thread group
    ThreadGroup threadGroup = new ThreadGroup();
    threadGroup.setNumThreads(1);
    threadGroup.setRampUp(1);
    threadGroup.setSamplerController(loopController);
    threadGroup.setProperty(TestElement.TEST_CLASS, ThreadGroup.class.getName());
    threadGroup.setProperty(TestElement.GUI_CLASS, ThreadGroupGui.class.getName());

    // create http sampler
    HTTPSampler httpSampler = new HTTPSampler();
    httpSampler.setProtocol("https");
    httpSampler.setDomain("myDomain.services.company.com");
    httpSampler.setPath("ims/login/v1/token");
    httpSampler.setMethod("POST");
    httpSampler.setFollowRedirects(true);
    httpSampler.setAutoRedirects(false);
    httpSampler.setUseKeepAlive(true);
    httpSampler.addArgument("client_id", "argValue1");
    httpSampler.addArgument("scope", "argValue2");
    httpSampler.addArgument("userName", "abc%2B249%40gmail.com");
    httpSampler.addArgument("password", "Abc123");
    httpSampler.setProperty(TestElement.TEST_CLASS, HTTPSampler.class.getName());
    httpSampler.setProperty(TestElement.GUI_CLASS, HttpTestSampleGui.class.getName());

    //Add sampler to the thread group

    HashTree testPlanHashTree = new HashTree();
    HashTree threadGroupHashTree = testPlanHashTree.add(testPlan, threadGroup);
    threadGroupHashTree.add(httpSampler);

    // Generating the JMX file
    SaveService.saveTree(testPlanHashTree, new FileOutputStream(JMeterUtils.getJMeterHome() + "/bin/Test2.jmx"));
}
