I need to create a JMeter test that runs until a specific time, entered on the command line. For example:

jmeter.bat -DStopAt=10:00:00 MyTest.jmx

Can this be done with the 'End Time' in the thread scheduler? Or do I need a 'While' loop? How do I use the 'StopAt' parameter passed in on the command line?

You have 2 options:

  1. Change JMeter .jmx file before test runs:

    • Enable "Scheduler" and save your test script.
    • Look for the line like

      <longProp name="ThreadGroup.end_time">1481608595082</longProp>
      

      you will have different numeric value. It is basically test stop time in Unix time.

    • Substitute this value with the value you need
  2. Do it dynamically, but you will have to do some scripting

    • Add a separate Thread Group
    • Add a Beanshell Sampler to this Thread Group
    • Put the following code into the Beanshell Sampler's "Script" area

      import java.text.SimpleDateFormat;
      
      String input = System.getProperty("StopAt");
      SimpleDateFormat sdf = new SimpleDateFormat("hh:mm:ss");
      Date now = new Date();
      Date stop = sdf.parse(input);
      Calendar cal = Calendar.getInstance();
      int year = cal.get(Calendar.YEAR);
      int month = cal.get(Calendar.MONTH);
      int day = cal.get(Calendar.DAY_OF_YEAR);
      cal.setTime(stop);
      cal.set(Calendar.YEAR, year);
      cal.set(Calendar.MONTH, month);
      cal.set(Calendar.DAY_OF_YEAR, day);
      stop = cal.getTime();
      
      if (now.compareTo(stop) >= 0) {
          log.info("--- Stopping the test --- ");
          SampleResult.setStopTest(true);
      }
      

    SampleResult - is a pre-defined variable which stands for current (Beanshell Sampler) SampleResult, see the JavaDoc for all available methods and fields, the most interesting in your case are:

    • setStopTest() - ASK threads to stop (graceful shutdown may require some time)
    • setStopTestNow() - TELL threads to stop (you may have some extra errors due to abnormal threads termination)
