我的测试脚本的层次结构如下：

- test plan
  - thread group 1
    - http sampler 1-1

  - thread group 2
    - http sampler 2-1
- thread group 1
    - http sampler 1-1

  - thread group 3
    - http sampler 3-1

我可以遍历所有的线程组。但是，我不能使用类似的模式来遍历http采样器。
下面是我的代码：

public static void main(String[] args) throws IOException {
        // LOAD EXITISTING JMETER XML
        JmxReader jmxReader = new JmxReader(".\\resources\\manually-configure.jmx");
        HashTree testPlanTree = jmxReader.getTree();

        SearchByClass testPlanSearcher = new SearchByClass(TestPlan.class);
        SearchByClass threadGroupSearcher = new SearchByClass(ThreadGroup.class);
        SearchByClass httpSamplerSearcher = new SearchByClass(HTTPSampler.class);
        testPlanTree.traverse(testPlanSearcher);
        Iterator testPlanIter = testPlanSearcher.getSearchResults().iterator();

        while (testPlanIter.hasNext()) { // This loop will only execute once, due to we only have one test plan
            TestPlan testPlan = (TestPlan) testPlanIter.next();
            HashTree subTreeOfTestPlan = testPlanSearcher.getSubTree(testPlan);
            subTreeOfTestPlan.traverse(threadGroupSearcher);
            Iterator threadGroupIter = threadGroupSearcher.getSearchResults().iterator();
            while(threadGroupIter.hasNext()) {
                ThreadGroup threadGroup = (ThreadGroup) threadGroupIter.next();
                HashTree subTreeOfThreadGroup = threadGroupSearcher.getSubTree(threadGroup);
                subTreeOfThreadGroup.traverse(httpSamplerSearcher);
                Iterator httpSamplerIter = httpSamplerSearcher.getSearchResults().iterator();

                while (httpSamplerIter.hasNext()) {
                    httpSamplerIter.next();
                    System.out.println("I found a http sampler"); \\ ??? Nothing got printed
                }
            }
         }
    }

遍历http smapler的第三个内部循环不会执行。但是，每个线程组中至少有一个采样器。
