纯粹用Java创建一个新的JMeter测试，但另存为有效*.jmx

Question

我遵循这个线程中介绍的方法，然后按以下方式保存hashTree：

    FileOutputStream out = new FileOutputStream("test.jmx");
    SaveService.saveTree(hashTree, out);

是否可以保存和恢复已创建的测试？

另一方面，GitHub上有一个项目来创建和保存Test。结果到底是不是有效的JMX文件。

guiclass="TestPlanGui" testclass="TestPlan" 

    mc.setProperty(new StringProperty(TestElement.GUI_CLASS, this.getClass().getName()));
    mc.setProperty(new StringProperty(TestElement.TEST_CLASS, mc.getClass().getName()));

Answer 1

您很可能忘记设置以下属性：

• testelement.test_class
• testelement.gui_class

如果省略它们，您仍然可以使用JMeterEngine运行测试，但是在GUI中打开生成的脚本的尝试将失败。
