Runing test script in multiple browsers using WebDriver

we can run test script in different browsers using web driver. Write one test script and configure in testng xml to run that test case in IE, firefox chrome.

package com.web;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.testng.Assert;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
public class WebDriverDemo {

 private static WebDriver driver = null;
 @Parameters( {"BROWSER"}) 
 public  void testread(String BROWSER)throws Exception{

  System.out.println("Browser: " + BROWSER);

  if (BROWSER.equals("FF")) {
   System.out.println("FF is selected");
   driver = new FirefoxDriver();
  } else if (BROWSER.equals("IE")) {
   System.out.println("IE is selected");
   driver = new InternetExplorerDriver();
  } else if (BROWSER.equals("HU")) {
   System.out.println("HU is selected");
   driver = new HtmlUnitDriver();
  } else if (BROWSER.equals("CH")){
   System.out.println("Google chrome is selected");
   driver = new ChromeDriver();
  WebElement search= driver.findElement("p"));
  search.sendKeys("automation blog by niraj");
  Assert.assertTrue(driver.getPageSource().contains(""),"Failed in "+ BROWSER);


In the above sample program BROWSER is a variable which value would be passed from TestNG.xml and TestNG.xml will run the test multiple time each time BROWSER value would be set with different browser name and test will check the BROWSER value and decide which browser test will run.
