使用 JSR223 采样器创建 JMeter 测试计划
Create JMeter Test Plan using JSR223 Sampler
我是 Jmeter 的新手，我目前的要求是在 Java 中使用 JSR223 采样器创建一个 JMeter 测试计划，然后触发它。
我尝试的第一步是 运行 jmx 文件（在脚本区域使用 JSR223 采样器和 java 代码片段）通过 Java 但出现以下错误 - javax.scripts.ScriptException: 找不到名为 : ' 的引擎
java'，确保在 JSR223 测试元素中设置语言字段：JSR223 采样器。
我的代码：
File jmeterHome = new File(System.getProperty("jmeter.home"));
字符串斜杠 = 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();
}
}
如果你想“创建”一个测试计划，你真的应该“创建”它，这听起来像是你想从在线资源复制和粘贴现成的解决方案，或者请别人为你编写脚本.
我希望您展示您的代码并突出显示有问题的地方，而不是要求实施测试计划。
随便。
以下是使用 Java 代码实例化 JSR223 Sampler 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());
