Running Selenium test cases in parallel on multiple systems.

[arjun]

Hi,

I want to run my test cases in parallel on multiple platforms like different systems. I am executing test cases through Selenium Webdriver. I have configured Hub and more than 2 nodes and now want to run test cases in parallel.

Please help me guys if you have any knowledge regarding it.

Thanks.

It sounds like you are almost there. If the hub is already up and you have at least one node connected, then the only thing left is to point your WebDriver instances to the hub URL. There is a wiki page on it at: https://code.google.com/p/selenium/wiki/Grid2

Assuming you are using Java and TestNG you can refer here : http://rationaleemotions.wordpress.com/2013/07/31/parallel-webdriver-executions-using-testng/

Hi Krishnan,
                   Try to run the selenium with browsermobProxy + Selenium+TestNG combination. I am getting below error when trying  to run the multiple threads

The error doesn’t seem to have anything to do with parallel execution.

 

Have you tried to run just one single test for firefox ? To me it sounds like are having basic issues w.r.t firefox.

 

Can you please try using the latest version of :

 

• Selenium (3.4.0)
• GeckoDriver (v0.16.1)
• Latest nightly build of Firefox

 

You can refer to this release notes of GeckoDriver for more information.

 

Thanks & Regards

Hi ,
      I am running selenium(2.53) and firefox 40 for my project. I am running the testng suite programmatically using thread pool executors. I also wanted to use WebDriverBackedSelenium to use old selenium functions.

//Below is the execution code.
public class AdminCourseDashboardExecutor implements Runnable {

    @Override
    public void run() {
         TestNG tng = new TestNG();
             List<XmlSuite> suiteslist = new ArrayList<XmlSuite>();           
            List<XmlTest> testlist  = new ArrayList<XmlTest>();
            List<XmlClass> classeslist = new ArrayList<XmlClass>();
            List<Class> listenerClasses = new ArrayList<Class>();
               
            XmlSuite suite = new XmlSuite();
            suite.setName("

AdminCourseDashboardSuite");
     
            XmlTest test = new XmlTest(suite);
            test.setName("AdminCourseDashboardTest");
          
     
            XmlClass clss1 = new XmlClass(AdminCourseDashboard.class.getName());
            clss1.setName("AdminCourseDashboardClass");
            classeslist.add(clss1);
            test.setXmlClasses(classeslist);
            testlist.add(test);
            suite.setTests(testlist);
            suiteslist.add(suite);
            tng.setXmlSuites(suiteslist);
  
            tng.run();
        }
       

    public static void main(String args[]) throws InterruptedException{
        /* Paramater

         * */
         // String ClassName  =  args[0];
          String Threadpoolsize =  args[0];
          String SuiteName =  args[1];
          String TimeToRun = args[2];
          System.out.println(Threadpoolsize+"   "+SuiteName+"   "+TimeToRun+"   ");
          ScheduledExecutorService scheduledThreadPool = Executors.newScheduledThreadPool(Integer.parseInt(Threadpoolsize));

            long startTime = System.currentTimeMillis();
            long TimeDuration1 =  Integer.parseInt(TimeToRun)*60*1000;
           
            //new AdminCourseDashboardExecutor().run();
         for(int i=0; i<10; i++)    {   
               Thread.sleep(20000);
                scheduledThreadPool.scheduleAtFixedRate(new AdminCourseDashboardExecutor(),5, 120, TimeUnit.SECONDS);
            }
           
            scheduledThreadPool.awaitTermination((startTime+TimeDuration1)-System.currentTimeMillis(), TimeUnit.MILLISECONDS);
            scheduledThreadPool.shutdown();
    }
