Selenium WebDriver and TestNG: Running script in different browsers |Invoke different browsers

In this post will cover how to run a selenium script in different browsers.

To do so we will use TestNG and @Parameters annotation. Using TestNG we can directly pass parameter to test methods from testng.xml.  Below example makes it more clear

Prerequisites:

Download Chromedriver

Download Internet Explorer driver

Java

• Create a java class name BrowserContoller.java in your workspace.
• Create a method setBrowser(String browser) to your class. This method takes a String as input parameter.
• Add the annotation @Parameters ("browser") to this method. Value to the parameter will be passed from xml.

	package com.example.tests;
	import java.util.concurrent.TimeUnit;
	import org.openqa.selenium.WebDriver;
	import org.openqa.selenium.chrome.ChromeDriver;
	import org.openqa.selenium.firefox.FirefoxDriver;
	import org.openqa.selenium.ie.InternetExplorerDriver;
	import org.testng.annotations.AfterTest;
	import org.testng.annotations.BeforeTest;
	import org.testng.annotations.Parameters;
	import org.testng.annotations.Test;
	public class BrowserController {
	private WebDriver driver;
	/**
	* Invokes WebDriver instance for given browser.
	* @method public void setBrowser(String browser)
	* @param browser
	*/
	@BeforeTest
	@Parameters("browser")
	public void setBrowser(String browser) throws Exception
	{
	if(browser.equalsIgnoreCase("firefox")){
	driver = new FirefoxDriver();
	}
	if(browser.equalsIgnoreCase("chrome")){
	//path to Chrome driver
	String path = "E:\\drivers\\chromedriver.exe";
	System.setProperty("webdriver.chrome.driver",path);
	driver = new ChromeDriver();
	}
	if(browser.equalsIgnoreCase("iexplore")){
	//path to IE driver
	String path = "E:\\drivers\\IEDriverServer.exe";
	System.setProperty("webdriver.ie.driver",path);
	driver = new InternetExplorerDriver();
	}
	driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
	}
	/**
	* Launch the specified Application URL
	* @throws Exception
	*/
	@Test
	public void launchApplication() throws Exception
	{
	driver.get("http://www.google.com");
	}
	/**
	* Stops the application by closing the WebDriver
	* @method public void stopApplication()
	*/
	@AfterTest
	public void stopApplication() throws Exception
	{
	driver.quit();
	}
	}

TestNG

• Create a simple tesng.xml name say BrowserControllerTestng.xml
• Define Test name, parameter and its value (firefox, chrome,  iexplore ) and class name.

	<?xml version="1.0" encoding="UTF-8"?>
	<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
	<suite name="Test Suite" verbose="1">
	<test name="Browser Test">
	<parameter name="browser" value="chrome"/>
	<classes>
	<class name="com.example.tests.BrowserController" />
	</classes>
	</test>
	</suite>
