如何从Java程序创建和运行Apache JMeter Test Scripts？
我想使用Apache JMeter提供的API从Java程序创建和运行测试脚本。 我已经理解了ThreadGroup和Samplers的基础知识。 我可以使用JMeter API在我的Java类中创建它们。
ThreadGroup threadGroup = new ThreadGroup(); LoopController lc = new LoopController(); lc.setLoops(5); lc.setContinueForever(true); threadGroup.setSamplerController(lc); threadGroup.setNumThreads(5); threadGroup.setRampUp(1); HTTPSampler sampler = new HTTPSampler(); sampler.setDomain("localhost"); sampler.setPort(8080); sampler.setPath("/jpetstore/shop/viewCategory.shtml"); sampler.setMethod("GET"); Arguments arg = new Arguments(); arg.addArgument("categoryId", "FISH"); sampler.setArguments(arg); 但是，我不知道如何创建一个组合线程组和采样器的测试脚本，然后从同一个程序执行它。 有任何想法吗？
如果我理解正确，您希望以编程方式从Java程序中运行整个测试计划。 就个人而言，我发现创建测试计划.JMX文件并在JMeter非GUI模式下运行更容易:)
这是一个简单的Java示例，它基于原始问题中使用的控制器和采样器。
import org.apache.jmeter.control.LoopController; import org.apache.jmeter.engine.StandardJMeterEngine; import org.apache.jmeter.protocol.http.sampler.HTTPSampler; import org.apache.jmeter.testelement.TestElement; import org.apache.jmeter.testelement.TestPlan; import org.apache.jmeter.threads.SetupThreadGroup; import org.apache.jmeter.util.JMeterUtils; import org.apache.jorphan.collections.HashTree; public class JMeterTestFromCode { public static void main(String[] args){ // Engine StandardJMeterEngine jm = new StandardJMeterEngine(); // jmeter.properties JMeterUtils.loadJMeterProperties("c:/tmp/jmeter.properties"); HashTree hashTree = new HashTree(); // HTTP Sampler HTTPSampler httpSampler = new HTTPSampler(); httpSampler.setDomain("www.google.com"); httpSampler.setPort(80); httpSampler.setPath("/"); httpSampler.setMethod("GET"); // Loop Controller TestElement loopCtrl = new LoopController(); ((LoopController)loopCtrl).setLoops(1); ((LoopController)loopCtrl).addTestElement(httpSampler); ((LoopController)loopCtrl).setFirst(true); // Thread Group SetupThreadGroup threadGroup = new SetupThreadGroup(); threadGroup.setNumThreads(1); threadGroup.setRampUp(1); threadGroup.setSamplerController((LoopController)loopCtrl); // Test plan TestPlan testPlan = new TestPlan("MY TEST PLAN"); hashTree.add("testPlan", testPlan); hashTree.add("loopCtrl", loopCtrl); hashTree.add("threadGroup", threadGroup); hashTree.add("httpSampler", httpSampler); jm.configure(hashTree); jm.run(); } }
依赖
这些是基于JMeter 2.9和使用的HTTPSampler所需的最小JAR。 其他采样器很可能具有不同的库JAR依赖性。
- ApacheJMeter_core.jar
- jorphan.jar
- 阿瓦隆框架-4.1.4.jar
- ApacheJMeter_http.jar
- 共享记录-1.1.1.jar
- logkit-2.0.jar
- 口 – 2.0.8.jar
- 公地IO-2.2.jar
- 公地lang3-3.1.jar
注意
- 在首次从JMeter安装/ bin目录复制之后，我还在Windows上的c：\ tmp中修改了jmeter.properties的路径。
- 我不确定如何为HTTPSampler设置转发代理。

我利用JMeter Java Api和Maven依赖创建了一个简单的概念validation项目： https ： //github.com/piotrbo/jmeterpoc
您可以生成JMeter项目jmx文件并从命令行执行它或直接从Java代码执行它。
由于jmx文件需要为每个TestElement存在’guiclass’属性，因此有点棘手。 要执行jmx，添加guiclass就足够了（即使值不正确）。 要在JMeter GUI中打开，需要为每个guiclass正确的值。
更令人讨厌的问题是基于条件的流量控制器。 JMeter API不会为您提供更多GUI。 您仍然需要将condition传递给IfController作为常规String 。 该字符串应包含javascript。 所以你有基于Java的项目与javascript，例如语法错误，你不会知道它，直到你执行你的性能测试:-(
可能是一个更好的替代方案来保持代码和IDE的支持而不是JMeter GUI是学习Scala并使用http://gatling.io/
在非GUI模式下运行要快得多。 制作了一个在后端模式下使用Jmeter然后解析XML文件以显示测试结果的项目。 看看这个repo- https://github.com/rohitjaryal/RESTApiAutomation.git
