Question

在JMeter GUI中，可以轻松添加监听器，例如“查看结果树”或“在表中查看结果”并添加文件名

我有一个创建并运行看起来像这个

的测试计划的方法

//JMeter Engine
StandardJMeterEngine jmeter = new StandardJMeterEngine();

//JMeter initialization (properties, log levels, locale, etc)
JMeterUtils.loadJMeterProperties("/path/to/apache-jmeter-4.0/bin/jmeter.properties");
JMeterUtils.setJMeterHome("/path/to/apache-jmeter-4.0");
JMeterUtils.initLogging();// you can comment this line out to see extra log messages of i.e. DEBUG level
JMeterUtils.initLocale();

// JMeter Test Plan, basic all u JOrphan HashTree
HashTree testPlanTree = new HashTree();

// HTTP Sampler
HTTPSampler httpSampler = new HTTPSampler();
httpSampler.setDomain("example.com");
httpSampler.setPort(80);
httpSampler.setPath("/");
httpSampler.setMethod("GET");

// Loop Controller
LoopController loopController = new LoopController();
loopController.setLoops(1);
loopController.addTestElement(httpSampler);
loopController.setFirst(true);
loopController.initialize();


// Thread Group
ThreadGroup threadGroup = new ThreadGroup();
threadGroup.setNumThreads(1);
threadGroup.setRampUp(1);
threadGroup.setSamplerController(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();

是否有一个方便的预制测试元素，可以简单地添加到线程组并将结果直接保存到文件中（与“查看表中的结果”监听器从gui执行的方式相同）。
实现执行此任务的侦听器的内容如何

编辑：我使用ResultCollector添加了更改并成功保存了文件data.csv但是，它只创建了csv列名但从未创建任何结果。

Summariser summer = null;
String summariserName = JMeterUtils.getPropDefault("summariser.name", "summary");//$NON-NLS-1$
if (summariserName.length() > 0) {
    summer = new Summariser(summariserName);
}

ResultCollector rc = new ResultCollector(summer);
rc.setFilename("C:\\Users\\user\\data.csv");
rc.setErrorLogging(true);

threadGroup.addTestElement(rc);
testPlanTree.add("rc", rc);

我的完整输出看起来像这样

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property 'log4j2.debug' to show Log4j2 internal initialization logging.

从代码中删除这些行：

threadGroup.addTestElement(rc);
testPlanTree.add("rc", rc);

并将其替换为以下内容：

testPlanTree.add(testPlanTree.getArray()[0], rc);

另请注意，如果你离开这一行：

rc.setErrorLogging(true);

您的.jtl结果文件中只有仅错误。

我也没有看到任何采样器被执行，因此请使用以下参考资料仔细检查您的测试计划：
