Road to parallel execution of selenium webdriver test using testng

In this post you will learn how to run selenium webdriver test scripts parallel in more two environments using testng suite, testng has a feature by which we can create multiple instance of a single testng class file.

In below example, I created a selenium webdriver test script for google search. Which will run on two browsers firefox and IE.

package com.test;

import java.io.File;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.*;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.openqa.selenium.ie.InternetExplorerDriver;

import org.testng.annotations.AfterClass;

import org.testng.annotations.BeforeClass;

import org.testng.annotations.Parameters;

import org.testng.annotations.Test;

public class GoogleTest {

  private WebDriver driver;

  private String baseUrl;

  @BeforeClass

  @Parameters({ "browsertype"})

  public void setUp(String browsertype) throws Exception {

    

     if(browsertype.contains("IE")) {

               File IEDriver = new File("IEDriverServer.exe");

               System.setProperty("webdriver.ie.driver", IEDriver.getAbsolutePath() );

               driver = new InternetExplorerDriver();

     }

     else if(browsertype.contains("Firefox")){

                  driver = new FirefoxDriver();

     }        

    baseUrl = "https://www.google.co.in/";

    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

    driver.manage().window().maximize();

  }

  @Test

  public void testUntitled() throws Exception {

    driver.get(baseUrl + "/");

    driver.findElement(By.id("gbqfq")).clear();

    driver.findElement(By.id("gbqfq")).sendKeys("Testing");

    driver.findElement(By.id("gbqfb")).click();

    driver.findElement(By.id("ab_opt_icon")).click();

    driver.findElement(By.cssSelector("#ab_as > div")).click();

    driver.findElement(By.xpath("//input[@value='Advanced Search']")).click();

  }

  @AfterClass

  public void tearDown() throws Exception {

    driver.quit();   

  }

}; 

In this test I used dataprovider annotation of testng so need to pass “browsertype” variable from testng suite.xml file.
Here is testng suite.xml file. You should add “parallel="tests” attribute in suite tag, thread-count value more than 2. Add attribute “preserve-order="true” in test tag.

Run testng suite.xml file you should see that two threads of “GoogleSearch” scripts will run parallel on firefox browser and another on IE browser. Hope this will help you tp parallel execution of selenium webdriver test scripts.
