純Java創建新的JMeter測試用於Java採樣器

Question

我創建了JMeter Java請求並將jar複製到ext目錄（apache-jmeter-3.1\lib\ext）。 我試圖在遠程機器上運行測試。在GUI中，我可以配置並運行Java請求。 也可以使用下面的JMX文件通過Java代碼調用測試。

ClientJMeterEngine jmeter = new ClientJMeterEngine("myclient"); 
File file = new File(RemoteJmeterTest.class.getResource("/finalSample.jmx").getFile()); 
JMeterUtils.loadJMeterProperties("D:/apache-jmeter-3.1/bin/jmeter.properties"); 
JMeterUtils.setJMeterHome("D:/Tools/apache-jmeter-3.1"); 

HashTree testPlanTree = SaveService.loadTree(file); 
jmeter.configure(testPlanTree); 
jmeter.runTest(); 

現在我想純粹用Java創建一個新的JMeter測試。但我不知道如何配置Java採樣器。 我看到示例here指出如何配置HTTP採樣器。 而不是HTTPSampler，我需要配置我的Java請求。 請協助。

示例代碼添加Java Request採樣器將執行SleepTest看起來像：

JavaSampler javaSampler = new JavaSampler(); 
javaSampler.setName("Java Request"); 
javaSampler.setClassname("org.apache.jmeter.protocol.java.test.SleepTest"); 
Arguments arguments = new Arguments(); 
arguments.addArgument("SleepTime", "1000"); 
arguments.addArgument("SleepMask", "0x33F"); 
javaSampler.setArguments(arguments); 
javaSampler.setProperty(TestElement.TEST_CLASS, JavaSampler.class.getName()); 
javaSampler.setProperty(TestElement.GUI_CLASS, JavaTestSamplerGui.class.getName()); 

在情況下，如果你需要執行自己的類實現JavaSamplerClient界面剛剛替補類名，並根據需要提供自己的論點。
