在Java中为Java Sampler创建一个新的JMeter测试
我创建了一个JMeter Java请求并将jar复制到ext目录（ apache-jmeter-3.1\lib\ext ）。 我正在尝试在远程计算机上运行测试。 从GUI我可以配置和运行Java请求。 也可以使用JMX文件通过Java代码调用测试，如下所示。
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();
现在我想用Java创建一个新的JMeter测试。 但我不知道如何配置Java采样器。 我在这里看到示例指向如何配置HTTP Sampler。 我需要配置我的Java请求，而不是HTTPSampler。 请协助。
添加将执行SleepTest的Java Request采样器的示例代码如下所示：
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());
如果您需要执行自己的类来实现JavaSamplerClient接口，只需替换类名并在需要时提供您自己的参数。
