在Java中为Java Sampler创建一个新的JMeter测试 [英] Creating a New JMeter Test Purely in Java for Java Sampler

问题描述

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。

I've created a JMeter Java request and copied the jar to ext directory (apache-jmeter-3.1\lib\ext). I'm trying to run the test on a remote machine. From the GUI I'm able to configure and run the Java request. Also able to invoke the test via Java code using the JMX file as below.

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。
我看到示例这里指出如何配置HTTP采样器。
我需要配置我的Java请求，而不是HTTPSampler。
请协助。

Now I want to creating a New JMeter Test Purely in Java. But I don't know how to configure the Java sampler. I see example here pointing how to configure the HTTP Sampler. Instead of HTTPSampler, I need to configure my Java Request. Please assist.

推荐答案

添加 Java Request 采样器将执行 SleepTest 将如下所示：

Example code to add a Java Request sampler which will execute SleepTest will look like:

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()); 

如果你需要执行你自己的类来实现 JavaSamplerClient 接口只需替换类名，并在需要时提供您自己的参数。

In case if you need execute your own class implementing JavaSamplerClient interface just substitute the classname and provide your own arguments if needed.
