JMeter - 如何执行 Http 请求列表并收集结果统计信息

Question

我需要按顺序执行 Http 请求列表并收集每个请求的结果/统计信息。映射将请求开始时间作为键，将请求对象作为值。

我可以分三步完成：

1. 使用 Oracle 表中显示的请求基础详细信息构建结果集

2. 迭代结果集。

   2a) 获取每条记录，创建包含详细信息的请求对象，并构建一个以请求开始时间为键、请求对象为值的映射。

   2b) 使用请求对象数据形成 SOAP 请求 XML 消息并将其作为值添加到 HttpArguement

   2c) 创建JMeter测试计划，配置JMeter，执行计划并收集结果

   2d) 根据请求之间的请求开始时间计算延迟时间，并将运行线程设置为休眠状态

3. 最后，服务在执行完所有记录后终止。

现在，我可以成功执行测试了。但是，我不确定这是正确的方法。请检查一下，如果我错了，请告诉我。

另外，现在我正在获取编码后的单个请求的结果摘要。但是，我喜欢在执行所有请求后获取累积统计信息。怎么做？请指导我。

完整代码如下：

// Build the result set [baseReqRecords] of request details from the database

while (baseReqRecords.next()) {
    // Get the request details
    // Get the start time

    long delay = 0;

    if (previousRequestStartTime != null) {
        delay = ((requestStartTime.getTime() - previousRequestStartTime
                .getTime()));
    }

    HTTPSamplerProxy httpSampler = new HTTPSamplerProxy();
    httpSampler.setName("SOAP Request");
    httpSampler.setEnabled(true);
    httpSampler.setPostBodyRaw(true);

    HTTPArgument httpArgument = new HTTPArgument();
    httpArgument.setAlwaysEncoded(false);
    httpArgument.setMetaData("=");

    if (operationsMap.get(reqOperation).equals(
            <<DESIRED_OPERATION>>)) {
        // build the request context object from the request details
        httpArgument.setValue(<<SOAP MESSAGE>>);
    }

    Arguments arguments = new Arguments();
    arguments.addArgument(httpArgument);

    System.out.println("HTTP Argument value: "
            + httpArgument.getValue());

    HeaderManager headerManager = new HeaderManager();
    headerManager.add(new Header("<<SM_USER>>",
            "<<value>>"));
    headerManager.add(new Header("Content-Type",
            "text/xml; charset=utf-8"));
    headerManager
            .add(new Header(
                    "SOAPAction",
                    "<<ACTION_URL>>"));
    headerManager.setName(JMeterUtils
            .getResString("header_manager_title"));
    headerManager.setProperty(TestElement.GUI_CLASS,
            HeaderPanel.class.getName());
    headerManager.setProperty(TestElement.TEST_CLASS,
            HeaderManager.class.getName());

    System.out.println("Headers: " + headerManager.getHeaders());

    httpSampler.setArguments(arguments);
    httpSampler.setDomain("<<SERVER>>");
    httpSampler.setPort(<<PORT>>);
    httpSampler
            .setPath("<<PATH>>");
    httpSampler.setMethod("POST");
    httpSampler.setName("Sampler");
    httpSampler.setFollowRedirects(true);
    httpSampler.setAutoRedirects(false);
    httpSampler.setUseKeepAlive(true);
    httpSampler.setDoMultipartPost(false);
    httpSampler.setMonitor(false);
    httpSampler.setProperty(TestElement.GUI_CLASS,
            HttpTestSampleGui.class.getName());
    httpSampler.setProperty(TestElement.TEST_CLASS,
            HTTPSamplerProxy.class.getName());

    LoopController loopController = new LoopController();
    loopController.setEnabled(true);
    loopController.setFirst(true);
    loopController.setContinueForever(false);
    loopController.setLoops(1);
    loopController.setProperty(TestElement.GUI_CLASS,
            LoopControlPanel.class.getName());
    loopController.setProperty(TestElement.TEST_CLASS,
            LoopController.class.getName());
    loopController.initialize();

    ThreadGroup threadGroup = new ThreadGroup();
    threadGroup.setNumThreads(1);
    threadGroup.setRampUp(1);
    threadGroup.setScheduler(false);
    threadGroup.setSamplerController(loopController);
    threadGroup.setEnabled(true);
    threadGroup.setProperty(TestElement.GUI_CLASS,
            ThreadGroupGui.class.getName());
    threadGroup.setProperty(TestElement.TEST_CLASS,
            ThreadGroup.class.getName());

    TestPlan testPlan = new TestPlan(
            "Test Plan");
    testPlan.setComment("Service Operations Test Plan");
    testPlan.setFunctionalMode(false);
    testPlan.setSerialized(false);
    testPlan.setUserDefinedVariables((Arguments) new ArgumentsPanel()
            .createTestElement());
    testPlan.setProperty(TestElement.GUI_CLASS,
            TestPlanGui.class.getName());
    testPlan.setProperty(TestElement.TEST_CLASS,
            TestPlan.class.getName());

    HashTree testPlanTree = new HashTree();

    HashTree samplerTree = new HashTree();
    samplerTree.add(httpSampler, headerManager);

    testPlanTree.add(testPlan);
    HashTree threadGroupHashTree = testPlanTree.add(testPlan,
            threadGroup);
    threadGroupHashTree.add(samplerTree);

    SaveService.saveTree(testPlanTree, new FileOutputStream(
            "jmeter_api.jmx"));

    Summariser summary = null;
    String summariserName = JMeterUtils.getPropDefault(
            "summariser.name", "summary");
    if (summariserName.length() > 0) {
        summary = new Summariser(summariserName);
    }

    String reportFile = "report.jtl";
    ResultCollector logger = new ResultCollector(summary);
    logger.setFilename(reportFile);
    testPlanTree.add(testPlanTree.getArray()[0], logger);

    jmeter.configure(testPlanTree);

    previousRequestStartTime = requestStartTime;
    jmeter.run();

    System.out.println("delay = " + delay);

    Thread.sleep(delay);
}

假设结果集中有 5 条请求详情记录。请求开始时间差为 60 秒。现在，我执行后收到如下结果：

summary =      1 in 00:00:01 =    0.9/s Avg:  1002 Min:  1002 Max:  1002 Err:     0 (0.00%)
delay = 0
summary =      1 in 00:00:01 =    1.1/s Avg:   850 Min:   850 Max:   850 Err:     0 (0.00%)
delay = 60000
summary =      1 in 00:00:01 =    1.5/s Avg:   612 Min:   612 Max:   612 Err:     0 (0.00%)
delay = 60000
summary =      1 in 00:00:01 =    1.1/s Avg:   859 Min:   859 Max:   859 Err:     0 (0.00%)
delay = 60000
summary =      1 in 00:00:01 =    1.1/s Avg:   849 Min:   849 Max:   849 Err:     0 (0.00%)

Answer 1

统计信息写入report.jtl文件，您可以使用您选择的Listener打开它，即Aggregate Report并查看请求摘要。您还可以使用 report.jtl 文件构建一个 HTML Reporting Dashboard，例如：

jmeter -g report.jtl -o /path/to/report/folder

我建议为您的请求使用不同的标签，因为它们都有SOAP Request 名称，因此无法在最终报告中区分它们。

其实你甚至不需要Java API，你可以使用JDBC Request sampler从Oracle获取请求数据，使用ForEach Controller迭代结果集。
