JMeter 测试中的吞吐量控制器自动化？

Question

我正在从事一个项目，在该项目中我必须将 JMeter 测试自动化作为后端服务。我的测试计划是这样的

Thread Group
 -Throughput Controller1
       --sampler1

 -Throughput controller2
       --sampler2

我的一个示例吞吐量实现是这样的。在这里，我正在做的是将线程数最初设置为 10，然后我想将其控制为 3 的线程数，另一个采样器的线程数为 7。

TestPlan testPlan = new TestPlan();
testPlan.setProperty(TestElement.TEST_CLASS, TestPlan.class.getName());
testPlan.setProperty(TestElement.GUI_CLASS, TestPlanGui.class.getName());
testPlan.setUserDefinedVariables((Arguments) new ArgumentsPanel().createTestElement());

SetupThreadGroup threadGroup = new SetupThreadGroup();
threadGroup.setRampUp(1);
threadGroup.setNumThreads(10);

ThroughputController throughputController = new ThroughputController();
throughputController.setComment("Through Put");
throughputController.setName("Through put");
throughputController.setMaxThroughput(3);
throughputController.setStyle(1);
   :
   :
   :
HTTPSamplerProxy examplecomSampler = loadTestSampler(urlDetails);

ListedHashTree testPlanTree = new ListedHashTree();
HashTree tpConfig = testPlanTree.add(testPlan);
HashTree tgConfig = tpConfig.add(threadGroup);
tgConfig.add(throughputController);
tgConfig.add(examplecomSampler)

当我运行这 10 个线程调用 examplecomSampler。但我想将其限制为 3，将其他 7 限制为另一个采样器，这是为什么呢？

谢谢。

我不认为你初始化吞吐量控制器的方式是正确的，而且在没有看到你的 class 的完整代码的情况下很难说还有什么问题。

请注意，您应该使用 JMeter GUI, other ways are not officially supported, however you can try using wrapper tools like Taurus

创建 JMeter 测试计划

一般JMeter jmx scripts are basically XML files so you can compare the test plan you generate using JMeter API使用来自 JMeter GUI 的测试计划，识别差异并修改代码以消除它们。

如果您仍想进入以编程方式创建 JMeter 脚本的方向，一个示例测试计划具有 2 个吞吐量控制器和 2 个采样器，相应地配置为 30% 和 70% 的执行，如下所示：

HashTree testPlanTree = new HashTree();

HTTPSamplerProxy examplecomSampler = new HTTPSamplerProxy();
examplecomSampler.setDomain("example.com");
examplecomSampler.setPort(80);
examplecomSampler.setPath("/");
examplecomSampler.setMethod("GET");
examplecomSampler.setName("Open example.com");
examplecomSampler.setProperty(TestElement.TEST_CLASS, HTTPSamplerProxy.class.getName());
examplecomSampler.setProperty(TestElement.GUI_CLASS, HttpTestSampleGui.class.getName());

HTTPSamplerProxy blazemetercomSampler = new HTTPSamplerProxy();
blazemetercomSampler.setDomain("blazemeter.com");
blazemetercomSampler.setPort(80);
blazemetercomSampler.setPath("/");
blazemetercomSampler.setMethod("GET");
blazemetercomSampler.setName("Open blazemeter.com");
blazemetercomSampler.setProperty(TestElement.TEST_CLASS, HTTPSamplerProxy.class.getName());
blazemetercomSampler.setProperty(TestElement.GUI_CLASS, HttpTestSampleGui.class.getName());

LoopController loopController = new LoopController();
loopController.setLoops(1);
loopController.setFirst(true);
loopController.setProperty(TestElement.TEST_CLASS, LoopController.class.getName());
loopController.setProperty(TestElement.GUI_CLASS, LoopControlPanel.class.getName());
loopController.initialize();

ThreadGroup threadGroup = new ThreadGroup();
threadGroup.setName("Example Thread Group");
threadGroup.setNumThreads(1);
threadGroup.setRampUp(1);
threadGroup.setSamplerController(loopController);
threadGroup.setProperty(TestElement.TEST_CLASS, ThreadGroup.class.getName());
threadGroup.setProperty(TestElement.GUI_CLASS, ThreadGroupGui.class.getName());

ThroughputController throughputController3 = new ThroughputController();
throughputController3.setComment("Through Put 3");
throughputController3.setName("Through put 3");
FloatProperty throughput3 = new FloatProperty();
throughput3.setName("ThroughputController.percentThroughput");
throughput3.setValue(30.0f);
throughputController3.setProperty(throughput3);
throughputController3.setProperty("ThroughputController.style", 1);
throughputController3.setProperty("ThroughputController.perThread", false);
throughputController3.setProperty(TestElement.TEST_CLASS, ThroughputController.class.getName());
throughputController3.setProperty(TestElement.GUI_CLASS, ThroughputControllerGui.class.getName());

ThroughputController throughputController7 = new ThroughputController();
throughputController7.setComment("Through Put 7");
throughputController7.setName("Through put 7");
FloatProperty throughput7 = new FloatProperty();
throughput7.setName("ThroughputController.percentThroughput");
throughput7.setValue(70.0f);
throughputController7.setProperty(throughput7);
throughputController7.setProperty("ThroughputController.style", 1);
throughputController7.setProperty("ThroughputController.perThread", false);
throughputController7.setProperty(TestElement.TEST_CLASS, ThroughputController.class.getName());
throughputController7.setProperty(TestElement.GUI_CLASS, ThroughputControllerGui.class.getName());

HashTree logicHashTree = new HashTree();

HashTree throughputController3Tree = new HashTree();
HashTree exampleComHashTree = new HashTree();

exampleComHashTree.add(examplecomSampler);
throughputController3Tree.add(throughputController3);
throughputController3Tree.add(throughputController3, exampleComHashTree);

HashTree throughputController7Tree = new HashTree();
HashTree blazemeterComHashTree = new HashTree();

blazemeterComHashTree.add(blazemetercomSampler);
throughputController7Tree.add(throughputController7);
throughputController7Tree.add(throughputController7, blazemeterComHashTree);


logicHashTree.add(throughputController3Tree);
logicHashTree.add(throughputController7Tree);

TestPlan testPlan = new TestPlan("Create JMeter Script From Java Code");
testPlan.setProperty(TestElement.TEST_CLASS, TestPlan.class.getName());
testPlan.setProperty(TestElement.GUI_CLASS, TestPlanGui.class.getName());
testPlan.setUserDefinedVariables((Arguments) new ArgumentsPanel().createTestElement());

testPlanTree.add(testPlan);
HashTree threadGroupHashTree = testPlanTree.add(testPlan, threadGroup);
threadGroupHashTree.add(logicHashTree);
