Multi Browser Testing using Selenium TestNG

This Section describes how to run your Test cases on different browsers.

Few Simple steps Using TestNG :)

Step 1: Create your Script. Using TestNG annotations. Define parameters (using @Parameters) for taking input value i.e, which browser should be used for Running the Test

Step 2: Create a TestNG XML for running your script

Step 3: Configure the TestNG XML for passing parameters i.e, to tell which browser should be used for Running the Test

Step 4: Run the TestNG XML which can pass the appropriate browser name to the Script such that the Test Case is executed in a specified browser


Programatically this can be Done as follows:

Step 1:

package atu.multibrowser;

import org.openqa.selenium.By;

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.AfterClass;

import org.testng.annotations.BeforeClass;

import org.testng.annotations.Parameters;

import org.testng.annotations.Test;

public class MultiBrowserTest {

       private WebDriver driver;

       // Configure for multi browser drivers

       @Parameters("browser")

       @BeforeClass

       public void beforeTest(String browser) {

              if (browser.equalsIgnoreCase("firefox")) {

                     driver = new FirefoxDriver();

              } else if (browser.equalsIgnoreCase("chrome")) {

                     // Set Path for the executable file

                     System.setProperty("webdriver.chrome.driver",

                                  "D:\\chromedriver.exe");

                     driver = new ChromeDriver();

              } else if (browser.equalsIgnoreCase("ie")) {

                     // Set Path for the executable file

                     System.setProperty("webdriver.ie.driver", "D:\\IEDriverServer.exe");

                     driver = new InternetExplorerDriver();

              } else {

                     throw new IllegalArgumentException("The Browser Type is Undefined");

              }

              // Open App

              driver.get("http://demo.opensourcecms.com/wordpress/wp-login.php");

       }

       @Test

       public void login() throws InterruptedException {

              // Enter UserName

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

              driver.findElement(By.id("user_login")).sendKeys("admin");

              // Enter Password

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

              driver.findElement(By.id("user_pass")).sendKeys("demo123");

              // Click on Submit button

              driver.findElement(By.id("wp-submit")).submit();

       }

       @AfterClass

       public void afterTest() {

              try {

                     driver.quit();

              } catch (Exception e) {

                     driver = null;

              }

       }

}

Step 2 & Step 3: The below XML is configured to run the Test Case in Firefox, Chrome and IE browser in sequential manner

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

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

<suite name="Suite" parallel="none">

       <test name="FirefoxTest">

              <parameter name="browser" value="firefox" />

              <classes>

                     <class name="atu.multibrowser.MultiBrowserTest" />

              </classes>

       </test>

       <test name="ChromeTest">

              <parameter name="browser" value="chrome" />

              <classes>

                     <class name="atu.multibrowser.MultiBrowserTest" />

              </classes>

       </test>

       <test name="IETest">

              <parameter name="browser" value="ie" />

              <classes>

                     <class name="atu.multibrowser.MultiBrowserTest" />

              </classes>

       </test>

</suite>

Step 4:

Run the above XML as TestNG Suite from Eclipse IDE as shown below.

/***********************************************************************/

Enhancing your TestNG xml for running the Test Case on Different browsers Simultaneously. Speeding up the execution process :)

Using the feature provided by TestNG for Parallel Executions. Set the"parallel" attribute to "tests" so that the all the three browser tests can be executed Simultaneously.

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

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

<!--Change The Parallel attribute for parallel Execution-->

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

       <test name="FirefoxTest">

              <parameter name="browser" value="firefox" />

              <classes>

                     <class name="atu.multibrowser.MultiBrowserTest" />

              </classes>

       </test>

       <test name="ChromeTest">

              <parameter name="browser" value="chrome" />

              <classes>

                     <class name="atu.multibrowser.MultiBrowserTest" />

              </classes>

       </test>

       <test name="IETest">

              <parameter name="browser" value="ie" />

              <classes>

                     <class name="atu.multibrowser.MultiBrowserTest" />

              </classes>

       </test>

</suite>

This is one short and quick way of setting up Multiple Browser Testing :)
