This article introduces the knowledge of "how to create a controller and preprocessor only once through JAVA code". Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Jmeter: create an one-time controller from JAVA code (OnceOnlyController)

Recently, I have been studying the dynamic creation of Jmeter scripts through JAVA. For creating OnceOnlyController, I really did not find any relevant information, so I studied it myself. It is not very difficult. The code is as follows:

/ * create OnceOnlyController controller only once * @ param threadGroupHashTree * @ param taskId * / public static void createOnceOnlyController (HashTree threadGroupHashTree, String taskId) {OnceOnlyController onceOnlyController=new OnceOnlyController (); onceOnlyController.setProperty ("testname", "test"); onceOnlyController.setProperty ("enable", true); HashTree testPlanTree = new HashTree () TestPlanTree.add (createBeanShellPreProcessor (taskId)); BeanShellSampler beanShellSampler = new BeanShellSampler (); beanShellSampler.setName ("test" + taskId); beanShellSampler.setProperty ("BeanShellSampler.query", "); testPlanTree.add (beanShellSampler) / / add BeanShellPreProcessor and BeanShellSampler to threadGroupHashTree.add (onceOnlyController,testPlanTree) under OnceOnlyController;} / * create BeanShell preprocessor * @ return * / public static BeanShellPreProcessor createBeanShellPreProcessor (String taskId) {BeanShellPreProcessor preProcessor=new BeanShellPreProcessor (); preProcessor.setEnabled (true); preProcessor.setProperty ("resetInterpreter", false) String script= "System.out.println (\" preprocessing num:\ "+ ctx.getThreadNum ());"; preProcessor.setProperty ("script", script); preProcessor.setProperty (TestElement.ENABLED, true); preProcessor.setProperty (TestElement.NAME, "abcd") PreProcessor.setProperty (TestElement.TEST_CLASS, preProcessor.getClass (). GetName ()); preProcessor.setProperty (TestElement.GUI_CLASS, TestBeanGUI.class.getName ()); System.out.println ("createBeanShellPreProcessor:" + preProcessor.getPropertyAsString ("script")); return preProcessor } "how to create a controller and preprocessor only once through JAVA code" ends here.
