How to execute more than 1 xml file in PARALLEL with TestNG

[Manoj Kapuganti]

Hi All,

I want to execute multiple xml files (Example: 2 xml files) in parallel with eclipse.

Is there a way to achieve this alone with Eclipse & TestNG.

Best Regards,

Manoj Kapuganti

Hi  Manoj,

Maybe you can try like this:

        TestNG ng = new TestNG();

        ng.setXmlSuites([A list include your xml files]);

        ng.setSuiteThreadPoolSize(3);

        ng.run();

Hi Tim,

Thanks for you reply.

Could you please let me know how to use above code. Do I need to use listeners. If yes give me briefly.

Hello Tim,

Thank you so much for your help.

Now I am able to execute multiple xml files in parallel.

import java.io.FileNotFoundException;

import java.io.IOException;

import java.util.List;

import javax.xml.parsers.ParserConfigurationException;

import org.testng.xml.Parser;

import org.testng.xml.XmlSuite;

import org.testng.TestNG;

import org.xml.sax.SAXException;

public class MultipleXmls{

public static void main(String[] args) throws FileNotFoundException, ParserConfigurationException, SAXException, IOException {

TestNG testng = new TestNG(); 

testng.setXmlSuites((List <XmlSuite>)(new Parser("G:\\ManojKS\\Eclipse workspace\\Test1.xml").parse()));

testng.setSuiteThreadPoolSize(3);

testng.run();

    }

}

In Test1.xml content is

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

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="All Suites"> 

  <suite-files>

  <suite-file path="G:\ManojKS\Eclipse workspace\systemSettings\atest1.xml" />

  <suite-file path="G:\ManojKS\Eclipse workspace\systemSettings\atest2.xml" />

  <suite-file path="G:\ManojKS\Eclipse workspace\systemSettings\atest3.xml" />

  </suite-files>

</suite>

Thank you so much for your help again.

Best Regards,

Tim,

Am curious to know:

1.  How do you do this via the TestNG xml suite file [without using the TestNG APIs]

2.  How do you determine that the suites are INDEED running in parallel ? [Thread.getCurrentThread().getId() ?  I see the suites run in parallel when i merely enable parallelism at every suite level itself. So trying to understand the relevance and difference ]

would you happen to know ?

Hi  Krishnan ,

For Q1, I do not know how to do this though the xml files, according to the documents of testng, do not find related contents.

For Q2,  I do not try this before, I just provide a possible solution according the meaning of API. :) Thanks for your reminder, I need have a try for this.

Hello Manoj,

Are you using Grid 2.0 to run your Sites parallel??and also please tell me can we generate XSLT reports when running TestNG programatically ??

Please advise me

Advanced Thanks

Rao

[Manoj Kapuganti]

Hello Rao,

I am not using Grid.

By using testng.setSuiteThreadPoolSize(10) we can run 10 suites in parallel.

Please see the post on Aug 9, all details including script was pasted over there.

I am not aware of XSLT reports.

Let me know if you need any other details

Best Regards,

Manoj Kapuganti

[Rao]

Hello Manoj

Thanks for quick reply, In my TestBase class (I am running my suites parallel in multiple browsers by reading Browser parameter from XML file)

@Parameters ({"browsername"} )

public void openBrowser(String browser) throws MalformedURLException{

if (!isBrowserOpened) {

driver = new ThreadLocal<RemoteWebDriver>();

DesiredCapabilities dc = new DesiredCapabilities();

if (browser.equalsIgnoreCase("firefox")){

dc.setBrowserName(DesiredCapabilities.firefox().getBrowserName());

driver.set(new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),dc));

}

if (browser.equalsIgnoreCase("iexplorer")){

dc.setBrowserName(DesiredCapabilities.internetExplorer().getBrowserName());

driver.set(new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),dc));

}

if (browser.equalsIgnoreCase("chrome")){

dc.setBrowserName(DesiredCapabilities.chrome().getBrowserName());

driver.set(new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),dc));

}

isBrowserOpened = true;

}

}

My XML file is like below

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

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Selenium2 Grid with webdriver2" verbose="3" parallel="classes" thread-count="4" >

  <test name="Test LG04" >

<parameter name="browsername" value="chrome" />

    <classes>

      <class name="com.exony.test.framework.login.TestCase_LG04" />

    </classes>

   

  </test>

  <test name="Test LG04_FireFox">

    <parameter name="browsername" value="firefox" />

    <classes>

      <class name="com.exony.test.framework.login.TestCase_LG04" />

    </classes>

  </test>

  <!-- <test name="Test LG06">

<parameter name="browsername" value="firefox"/> 

   <classes>

        <class name="com.exony.test.framework.login.TestCase_LG04" ></class>  

</test>

</suite>

In the above xml file i am specifying the same class to run in both browsers at a time. Manoj, do you know how can specify in TestNg.Xml to run the Suites in multiple browsers at a time. please help me with this

Advanced Thanks

Rao

[Manoj Kapuganti]

Hello Rao,

Please use below Xml file

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

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Selenium2 Grid with webdriver2" verbose="3" parallel="tests">

<test name="Test LG04" >

<parameter name="browsername" value="chrome" />

    <classes>

      <class name="com.exony.test.framework.login.TestCase_LG04" />

    </classes>

</test>

  <test name="Test LG04_FireFox">

    <parameter name="browsername" value="firefox" />

    <classes>

      <class name="com.exony.test.framework.login.TestCase_LG04" />

    </classes>

</test>

<test name="Test LG06">

<parameter name="browsername" value="firefox"/> 

   <classes>

        <class name="com.exony.test.framework.login.TestCase_LG04" ></class>  

</test>

</suite>

Rightclick on xml file, choose Run as TestNG. By executing this all 3 tests will start in parallel.

Here you are using only 1 suite. But your in your question you said to execute multiple suites...

Please let me know if you have any queries.

Best Regards,

Manoj Kapuganti

[mummana subramanya]

thanks to uh and especially tim for providing the solution for parallel execution of test suites :) before parallel execution it took 5mins approx to complete the all test cases since m using selenium grid its getting completed  with 3 mins :)

Friends pls help me with this, its easy to solve for experts like you, and it's all ready solved one but i am using the same code as Manoj mentioned , but facing the nullpointerexception.

kindly help me in this regard.

Rishi

[Himanshu Shekhar]

Hello Saptha,

If you are still facing the same error, could you please try running again after making the following changes:

• Replace  testng.setSuiteThreadPoolSize(3); to  testng.setSuiteThreadPoolSize(2); since in your case you are using just two test suites.

HI Manoj,

I am looking for same solution, but the interesting part I would like to hear from you is How can I achieve the same with Selenium Grid and Ant run.

Appreciate your feedback, thanks in adv.

Hi Manoj, 

I used the same below code but i get the following error

Two suites cannot have the same name: Test, where as both sub xml have different suite name, What i Observe is it all the iteration it is picking only first xml and it throws this error.

testng.setXmlSuites((List <XmlSuite>)(new Parser("G:\\ManojKS\\Eclipse workspace\\Test1.xml").parse())); Is this line iterates all xmls properly

Any help on this is really appreciated

Thanks and Regards,

Sayed MCK

Sayeed,

That error message is self explanatory. Please ensure that the name attribute of your <suite> tag all have unique names and that there are no duplications. That should fix your problem.

Hi All,

I am facing the same problem, when I have single test in two testng.xml(testng1.xml & testng2.xml) files means, browsers are launched simultaneously. 

But when I have more than one test in two testng.xml files means, testng2.xml file gets triggered only after testng1.xml file gets completed. 

Please check the below example.

testng1.xml

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

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Parallel suite 1" >

  <test name="Functional_Test_1">

   <parameter name="browser" value="Chrome" />

    <classes>    

      <class name="com.simpletest.sample1"/>

    </classes> 

  </test> 

   <test name="Functional_Test_2">

    <classes>    

       <class name="com.simpletest.sample2"/>

     </classes> 

  </test> 

</suite>

testng2.xml

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

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Parallel suite 2" >

  <test name="Functional_Test_3">

   <parameter name="browser" value="Chrome" />

    <classes>    

      <class name="com.simpletest.demo1"/>

    </classes> 

  </test> 

   <test name="Functional_Test_4">

     <classes>    

       <class name="com.simpletest.demo2"/>

     </classes> 

  </test> 

</suite>

combinesuite.xml :

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

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="suite of suites"  parallel="classes" thread-count="2" >

    <suite-files>

        <suite-file path="testng1.xml" />

        <suite-file path="testng2.xml" />

    </suite-files>

</suite>

Kindly help me out to fix this issue.
