如何以编程方式从代码运行jMeter基准测试？

我想通过代码对一些远程API调用进行基准测试。到目前为止，我一直在使用JMH，但它不太适合我作为压力测试工具的需要（JMH非常适合微基准测试，其中代码片段是非常快速的基准测试）。我的远程API会在数十秒内响应，因此我确实需要使用以下工具运行测试：

多参数化输入

多个客户端线程（控制负载）

我可以通过JMeterUI中的手动测试实现很多功能，但是我想编写一些java测试/基准测试，它们使用JMeter并执行相同的操作。有没有办法做到这一点？

您可以启动现有的JMeter测试，也可以使用

运行现有测试示例代码：

import org.apache.jmeter.engine.StandardJMeterEngine;
import org.apache.jmeter.reporters.ResultCollector;
import org.apache.jmeter.reporters.Summariser;
import org.apache.jmeter.save.SaveService;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;

import java.io.File;

public class RunExistingJMeterTest {

    public static void main(String[] args) throws Exception {
        // Initialize properties
        JMeterUtils.loadJMeterProperties("/path/to/your/jmeter/bin/jmeter.properties");        

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


        // Initialize logging, locale, etc.
        JMeterUtils.setJMeterHome("/path/to/your/jmeter");
        JMeterUtils.initLocale();

        // Initialize JMeter SaveService
        SaveService.loadProperties();

        // Load existing .jmx Test Plan
        HashTree testPlanTree = SaveService.loadTree(new File("/path/to/your/jmeter/extras/Test.jmx"));

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


        // Store execution results into a .jtl file
        String logFile = "/path/to/results/file.jtl";
        ResultCollector logger = new ResultCollector(summer);
        logger.setFilename(logFile);
        testPlanTree.add(testPlanTree.getArray()[0], logger);

        // Run JMeter Test
        jmeter.configure(testPlanTree);
        jmeter.run();

    }
}

        Summariser summer = null;
        String summariserName = JMeterUtils.getPropDefault("summariser.name", "summary");
        if (summariserName.length() > 0) {

        }
