使用 JSR223 采樣器創建 JMeter 測試計划

Question

我是 Jmeter 的新手，我目前的要求是在 Java 中使用 JSR223 Sampler 創建一個JMeter測試計划，然后觸發它。

我嘗試的第一步是通過 Java 運行 jmx 文件（在腳本區域中使用 JSR223 采樣器和 java 代碼片段），但出現以下錯誤 - javax.scripts.ScriptException：找不到名為“java”的引擎，請確保設置語言JSR223 測試元素中的字段：JSR223 采樣器。

我的代碼：

File jmeterHome = new File(System.getProperty("jmeter.home")); String slash = System.getProperty("file.separator");

    if (jmeterHome.exists()) {
        File jmeterProperties = new File(jmeterHome.getPath() + slash + "bin" + slash + "jmeter.properties");
        if (jmeterProperties.exists()) {
            //JMeter Engine
            StandardJMeterEngine jmeter = new StandardJMeterEngine();

            //JMeter initialization (properties, log levels, locale, etc)
            JMeterUtils.setJMeterHome(jmeterHome.getPath());
            JMeterUtils.loadJMeterProperties(jmeterProperties.getPath());
            JMeterUtils.initLogging();// you can comment this line out to see extra log messages of i.e. DEBUG level
            JMeterUtils.initLocale();

            SaveService.loadProperties();

            // JMeter Test Plan, basically JOrphan HashTree
            HashTree testPlanTree = SaveService.loadTree(new File(JMX FILE PATH))   

            // Run Test Plan
            jmeter.configure(testPlanTree);
            jmeter.run();


        }
    }

Answer 1

如果你想“創建”一個測試計划，你真的應該“創建”它，聽起來你想從在線資源中復制和粘貼一個現成的解決方案，或者讓別人為你編寫腳本。

我希望您展示您的代碼並突出顯示有問題的地方，而不是要求實施測試計划。

任何。

以下是使用 Java 代碼實例化JSR223 采樣器的方法：

JSR223Sampler jsr223Sampler = new JSR223Sampler();
jsr223Sampler.setName("JSR223 Sampler");
jsr223Sampler.setProperty("cacheKey", "true");
jsr223Sampler.setProperty("script", "println('Hello')");
jsr223Sampler.setProperty("scriptLanguage", "groovy");
jsr223Sampler.setProperty(TestElement.TEST_CLASS, JSR223Sampler.class.getName());
jsr223Sampler.setProperty(TestElement.GUI_CLASS, TestBeanGUI.class.getName());
