尝试使用JMeter API生成JMeter测试计划（jmx）：从代码创建的jmeter jmx文件与JMeter创建的jmeter jmx文件不匹配

尝试使用JMeter API生成JMeter测试计划（jmx）：从代码创建的jmeter jmx文件与JMeter创建的jmeter jmx文件不匹配

最后，在研究了jmeter源代码之后，我发现除了我在做什么之外，我还需要显式设置guiClass和testClass参数。

testPlan.setProperty（TestElement.TEST_CLASS，TestPlan.class.getName（））;
testPlan.setProperty（TestElement.GUI_CLASS，TestPlanGui.class.getName（））;

类似地，对于其他测试元素，例如ThreadGroup，JavaSampler等。

完整的代码如下，
