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创建的文件之间不匹配

Question

我正在尝试使用jmeter java api创建一个jmeter jmx文件.这就是我所做的,

1. gui.jmx

使用jmeter gui应用程序创建一个我可以比较的参考jmx文件.对于测试计划,我只在线程组中添加一个线程组和一个java采样器.所有值都是默认值.

1. code.jmx

使用jmeter java api,我创建了一个包含测试计划,线程组和java sampler的jmx文件.所有值均根据情况1设置.

从代码创建jmx文件后,我注意到以下差异,

1)gui.jmx中的节点由code.jmx中的以下内容替换

    <org.apache.jorphan.collections.HashTree>

虽然这不是问题,但是可以以某种方式生成以下标记,因为GUI保存它

    <hashTree>

2)测试元素节点在gui.jmx中包含属性'guiClass'和'testClass',例如,这些属性不是在code.jmx中生成的,我也没有找到任何API来显式设置它们- >由此生成的code.jmx没有在jmeter gui控制台中打开.这可能意味着生成的jmx只能在无控制台模式下使用.这是设计的吗？有没有办法通过代码使用jmeter apis添加这些属性？(不使用DOM作为黑客)

3)gui.jmx的xml结构如下,

    <hashTree>
    <TestPlan ...>
    ...
    </TestPlan>
    <hashTree>
    <ThreadGroup ...>
    ...
    </ThreadGroup>
    **<hashTree/>**
    </hashTree>
</hashTree>

请注意HashTree元素的嵌套.当在JMeter GUI中打开时,元素彼此嵌套.

code.jmx的xml结构如下,

<org.apache.jorphan.collections.HashTree>
    <TestPlan ...>
    ...
    </TestPlan>
    **<org.apache.jorphan.collections.HashTree/>**
    <ThreadGroup ...>
    ...
    </ThreadGroup>
    **<org.apache.jorphan.collections.HashTree/>**
</org.apache.jorphan.collections.HashTree>

请注意标记位置的差异.没有筑巢.他们都处于同一水平.为什么会这样呢？使用jmx api添加测试元素的正确方法是什么,以便哈希树元素在第一种情况下彼此嵌套？

Answer 1

最后在查看jmeter源代码之后,我想到除了我正在做的事情之外,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());

类似于其他测试元素,如ThreadGroup,JavaSampler等.
