Parallel execution of scripts with TestNG

TestNG gives us the facility to execute multiple tests in parallel and two different methods of doing it are:

Method 1: Having multiple test method in one class file

Step 1: Create a class file with name “DummyTest1” and add following code in it.

public class DummyTest1

{

       public WebDriver driver;

  @Test

  public void main()

  {

     driver.findElement(By.name("userName")).sendKeys("mercury");

     driver.findElement(By.name("password")).sendKeys("mercury");

     driver.findElement(By.name("login")).click();

  }

 

  @Test

  public void main1()

  {

     driver.findElement(By.name("userName")).sendKeys("mercury");

     driver.findElement(By.name("password")).sendKeys("mercury");

     driver.findElement(By.name("login")).click();

  }

  @BeforeMethod

  public void beforeMethod()

  {

      driver = new FirefoxDriver();

      driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

      driver.get("http://newtours.demoaut.com/");

  }

  @AfterMethod

  public void afterMethod()

  {

       driver.quit();

  }

}

Step 2: Add following code in testng.xml file. Make sure you add the right class name.

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

<suite name="Parallel test suite" parallel="methods" thread-count="2">

  <test name="Regression 1">

    <classes>

      <class name="AutomationFrameworkForDummy.DummyTest1"/>

    </classes>

  </test>

</suite>

Step 3: Run it and you will see multiple browser window in parallel.

Method 2:  Having two test method in two class file.

Step 1: Create a class file and add following code in it.

public class Chrome_Search {

    WebDriver driver;

    

    @BeforeTest

       @Parameters("browser2")

     public void test1(String browser2)

     {

              if(browser2.equalsIgnoreCase("chrome"))

              {

                     System.setProperty("webdriver.chrome.driver", "E://Rajesh Document//AutomationFrameworks//WordPressAutomation//Drivers//chromedriver.exe");

                       driver =new ChromeDriver();

                       driver.get("www.google.com");

                      

                 } 

              else

              {

                     System.out.println("Google Chrome"); 

              }

         }

  

   }

Step 2: Create another class file and add following code in that class file.

public class Mozilla_OpenAmazon {

    WebDriver driver;

       @BeforeTest

       @Parameters("browser1")

    public void launchbrowser(String browser1)

     {

              if(browser1.equalsIgnoreCase("firefox"))//For Firefox we dont need to download any jar file as we have Inbuilt firefox jar files

              {

                     driver=new FirefoxDriver(); 

                  System.out.println("Hello Google..."); 

                  driver.get("https://www.amazon.com/");

                  driver.findElement(By.id("twotabsearchtextbox")).sendKeys("Dolly");

                                                  

           }

              else

              {

                     System.out.println("Firefox"); 

              }

     }

              @AfterTest

              public void closeBrowser()

              {

                     driver.quit();

              }

}

Step 3: Add following code in testng.xml

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

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

  <suite name="Suite" parallel="tests">

  <test name="FirefoxTest" >

  <parameter name = "browser1" value="Firefox"/>

  <classes>

  <class name ="AutomationFrameworkForDummy.Mozilla_OpenAmazon"> </class>

  </classes>

  </test>

   

 

  <test name ="Chrome Test">

    <parameter name = "browser2" value="Chrome"/>

   <classes>

  <class name ="AutomationFrameworkForDummy.Chrome_Search"/>

  </classes>

   </test>

   </suite>

Step 4: Now Run it.
