selenium - Executing tests Concurrently on different OS and Browsers with WebDriver using Java and TestNG -

i have configured grid in system , written test script. can run test on specified os , browser on 1 os , 1 browser @ 1 time not os , browser simultaneously. here have done. please tell me how can configure can run in configured os in 1 time.

my script using java below:

import java.net.malformedurlexception; import java.net.url; import org.junit.afterclass; import org.openqa.selenium.*; import org.openqa.selenium.remote.desiredcapabilities; import org.openqa.selenium.remote.remotewebdriver; import org.testng.annotations.*;  public class gridwithwebdriver {      public webdriver driver;      @parameters({"browser"})     @beforeclass     public void setup(string browser) throws malformedurlexception {         desiredcapabilities capability=null;          if(browser.equalsignorecase("firefox")){             system.out.println("firefox");             capability= desiredcapabilities.firefox();             capability.setbrowsername("firefox");              capability.setplatform(org.openqa.selenium.platform.any);             //capability.setversion("");         }          if(browser.equalsignorecase("iexplore")){             system.out.println("iexplore");             capability= desiredcapabilities.internetexplorer();             capability.setbrowsername("iexplore");              capability.setplatform(org.openqa.selenium.platform.windows);             //capability.setversion("");         }          driver = new remotewebdriver(<span class="il_ad" id="il_ad11">new url</span>("http://localhost:4444/wd/hub"), capability);         driver.navigate().to("http://google.com");      }      @test     public void test_first() throws interruptedexception{         thread.sleep(3000);         webelement search_editbox   =   driver.findelement(by.name("q"));         webelement search_button    =   driver.findelement(by.name("btng"));         search_editbox.clear();         search_editbox.sendkeys("first");         search_button.click();     }      @test     public void test_second(){         webelement search_editbox   =   driver.findelement(by.name("q"));         webelement search_button    =   driver.findelement(by.name("btng"));         search_editbox.clear();         search_editbox.sendkeys("second");         search_button.click();     }      @afterclass     public void teardown(){         driver.quit();     } } 

testng.xml:

<suite name="selenium <span class="il_ad" id="il_ad7">grid with</span> webdriver" verbose="3"  parallel="classes" thread-count="2">      <test name="selenium grid demo">   <parameter name="browser" value="iexplore"/>     <classes>       <class name="tests.gridwithwebdriver"/>       <class name="tests.gridwithwebdriver1"/>     </classes>  </test>  </suite> 

aditya,

your code(testng.xml) running parallel test on different-different or same system should below:

testng.xml

 <!doctype suite system "http://testng.org/testng-1.0.dtd">     <suite name="my sample suite" verbose="3"  parallel="tests" thread-count="2">            <test name="run on firefox">         <parameter name="mybrowser"  value="firefox"/>         <parameter name="myip"  value="http://172.16.10.119:5566/wd/hub"/>         <classes>           <class name="testcases.login"/>         </classes>      </test>       <test name="run on chrome">         <parameter name="mybrowser"  value="chrome"/>         <parameter name="myip"  value="http://172.16.10.106:5567/wd/hub"/>         <classes>           <class name="testcases.login"/>         </classes>      </test>       </suite>  here trying acess 1 linux(ttp://172.16.10.119:5566) , 1 mac(http://172.16.10.106:5567) , sending ip , browser parameter. run parallel have mentioned in <testsuite> tag parallel="tests" thread-count="2" 

i hope pretty clear now.
