not running parallel using Testng

[Rajiv Nanduani]

Hi all,

I have to run my test parallel in different browsers at same time. I have used testng but still it is not running in parallel. It is running sequentially one by one.first it opens Firefox, after completion it open IE.

like my test() need to be run in fireox and test2() in IE parallel at same time


Please have a look & correct me if any thing wrong.

The issue lies in your suite xml file.

You asked TestNG to run "tests" in parallel but your suite xml has ONLY one test. Please donot confuse this test with the @Test annotated method.

Here a test means <test> tag.

Change your parallel="methods" and you should see parallelism kick in.

Hi Krishnan,

Thanks a lot for guiding me  I was confused with test. Now i have updated the xml file the but still it is not showing in parallel means two browsers are not opening at same time. it is opening one after one(after completion of one).

xml file
----------------------------------------

<?xml version="1.0" encoding="UTF-8"?>

<suite name="Selenium TestNG Suite" parallel="methods"
    thread-count="3">

    <test name="Selenium TestNG - 1">
        <classes>
            <class name="remotRuneWebdriver.ParallelRun" />
        </classes>
        </test>
       

         <test name="Selenium TestNG - 2">

        <classes>
            <class name="remotRuneWebdriver.ParallelRun" />
        </classes>
        </test>
</suite>

please guide me..

Rajiv,

You changed your suite to now include two tests :)

You should first ascertain if TestNG is indeed spawning your tests [@Test annotated methods] in parallel.

I normally use a 

System.out.println("Thread id = " + Thread.currentThread().getId());

to print the thread ids.

If I see the same value then it means there is no parallelism being involved. If I see unique values then it means TestNG is indeed spawning the tests in parallel.

On a side note, I think you need to spend some time trying to understand TestNG a bit more before you start using it in your Selenium Tests.

There are a lot of things that you haven't told us yet. You seem to be using the Grid. So you need to tell us how exactly you spawned the grid and the node etc.,

To summarise, your question doesnt have anything to do with Selenium/WebDriver for that matter, but seems to be a question related to TestNG. I would encourage you to post it on testng-users forum.

Thanks & Regards
Krishnan Mahadevan

Thanks Krishnan for replying..

I have checked thread id it is showing different for each test
Thread id = 11
internetExplorer Started
Thread id = 10
firefox Started
Thread id = 13
firefox Started
Thread id = 14
internetExplorer Started

There are a lot of things that you haven't told us yet. You seem to be using the Grid. So you need to tell us how exactly you spawned the grid and the node etc.,

I have started the seleium grid server

java -jar selenium-server-standalone-2.25.0.jar -role hub

and also started the node/webdriver

java -jar selenium-server-standalone-2.25.0.jar -role webdriver -hub http://localhost:4444/grid/register

[Krishnan Mahadevan]

So that answers your question. TestNG is indeed spawning your threads in parallel !

Thanks & Regards

ya but browsers are opening in sequentially... :(

[Isaac Howard]

Another thing to look at is how many instances of FF and IE are on the node? The default should be 5 FF and 5 IE, but if it's only running one instance of each.

2nd. you can also add this

<?xml version="1.0" encoding="UTF-8"?>

<suite name="Selenium TestNG Suite" parallel="methods" thread-count="3">

    <test name="Selenium TestNG - 1" parallel="tests" thread-count="2">

        <classes>
            <class name="remotRuneWebdriver.ParallelRun" />
        </classes>
        </test>
        

         <test name="Selenium TestNG - 2" parallel="tests" thread-count="2">

        <classes>
            <class name="remotRuneWebdriver.ParallelRun" />
        </classes>
        </test>
</suite>

To make your threaded 'methods' run in multiple threads.

Last but not least, what is the power behind your nodes? I've noticed that when running on 'not so awesome' VMs that the node can't handle lots of simultaneous connections, and it looks like it's executing in series.

[ALISTER ERNEST]

To add to Issac's point, if you have a default value of just 1 instance of firefox running on your system, then the tests will be sequential though your testng.xml wants them to run in parallel. You might want to provide more than 1 instance of firefox for the tests to start in parallel.

I usually start my firefox node like this. Try it and see if this helps.

java -jar selenium-server-standalone-2.25.0.jar -role node -hub http://localhost:4444/grid/register -maxSession 10 -browser browserName=firefox,platform=WINDOWS,maxInstances=10 -port 5555

Finally i am able to run in parallel mode. Thanks all for guiding me

Special thanks to krishnan & Issac

hers is the XML 

i have 4 @tests/methods in parallel.ParallelRUN java file

in Firefox max instance 5 so i used 4 threads for this <test name="Selenium TestNG - 1" parallel="methods" thread-count="4">

In IE only one max instance is supported so i did not used  parallel  for this  <test name="Selenium TestNG - 2" >

I need to run in two browsers (Firefox and IE) simultaneously   I used two tests in XML using parallel="tests" thread-count="2"> 

now its open 4 firefox browsers at one go

and one IE instance, run 4 times for IE
