Selenium automation framework: Selenium Interview Questions Part

Webdriver (Selenium ) Interview Questions and answers

Question 1: What is Selenium 2.0
Answer: Webdriver is open source automation tool for web application. WebDriver is designed to provide a simpler, more concise programming interface in addition to addressing some limitations in the Selenium-RC API.

Question 2: What is cost of webdriver, is this commercial or open source.
Answer: selenium is open source and free of cost.

Question 3: how you specify browser configurations with Selenium 2.0?
Answer: Following driver classes are used for browser configuration

· AndroidDriver,

· ChromeDriver,

· EventFiringWebDriver,

· FirefoxDriver,

· HtmlUnitDriver,

· InternetExplorerDriver,

· IPhoneDriver,

· IPhoneSimulatorDriver,

· RemoteWebDriver

Question 4: How is Selenium 2.0 configuration different than Selenium 1.0?
Answer: In case of Selenium 1.0 you need Selenium jar file pertaining to one library for example in case of java you need java client driver and also Selenium server jar file. While with Selenium 2.0 you need language binding (i.e. java, C# etc) and Selenium server jar if you are using Remote Control or Remote WebDriver.

Question5: Can you show me one code example of setting Selenium 2.0?
Answer: below is example

WebDriver driver = new FirefoxDriver();

driver.get("https://www.google.co.in/");

driver.findElement(By.cssSelector("#gb_2 > span.gbts")).click();

driver.findElement(By.cssSelector("#gb_1 > span.gbts")).click();

driver.findElement(By.cssSelector("#gb_8 > span.gbts")).click();

driver.findElement(By.cssSelector("#gb_1 > span.gbts")).click();

Question 6: Which web driver implementation is fastest?
Answer: HTMLUnitDriver. Simple reason is HTMLUnitDriver does not execute tests on browser but plain http request – response which is far quick than launching a browser and executing tests. But then you may like to execute tests on a real browser than something running behind the scenes

Question 7: What all different element locators are available with Selenium 2.0?
Answer: Selenium 2.0 uses same set of locators which are used by Selenium 1.0 – id, name, css, XPath but how Selenium 2.0 accesses them is different. In case of Selenium 1.0 you don’t have to specify a different method for each locator while in case of Selenium 2.0 there is a different method available to use a different element locator. Selenium 2.0 uses following method to access elements with id, name, css and XPath locator –

driver.findElement(By.id("HTMLid"));

driver.findElement(By.name("HTMLname"));

driver.findElement(By.cssSelector("cssLocator"));

driver.findElement(By. className ("CalssName”));

driver.findElement(By. linkText ("LinkeText”));

driver.findElement(By. partialLinkText ("PartialLink”));

driver.findElement(By. tagName ("TanName”));

driver.findElement(By.xpath("XPathLocator));

Question 8: How do I submit a form using Selenium?
Answer:

WebElement el = driver.findElement(By.id("ElementID"));

el.submit();

Question 9: How to capture screen shot in Webdriver?

Answer:

File file= ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

FileUtils.copyFile(file, new File("c:\\name.png"));

Question 10: How do I clear content of a text box in Selenium 2.0?

Answer:

WebElement el = driver.findElement(By.id("ElementID"));

el.clear();

Question 11: How to execute java scripts function.

Answer:

JavascriptExecutor js = (JavascriptExecutor) driver;

String title = (String) js.executeScript("pass your java scripts");

Road to verify 200 response code of web application in java webdriver

This post will help to verify HTTP response code 200 of web application using java webdriver. As webdriver does not support direct any function to verify page response code. But using "WebClient" of HtmlUnit API we can achieve this.

Html unit API is GUI less browser for java developer, using WebClent class we can send request to application server and verify response header status.

Below code, I used in my webdriver script to verify response 200 of web application

String url = "http://www.google.com/";

WebClient webClient = new WebClient();

HtmlPage htmlPage = webClient.getPage(url);

//verify response

Assert.assertEquals(200,htmlPage.getWebResponse().getStatusCode());

Assert.assertEquals("OK",htmlPage.getWebResponse().getStatusMessage());

If HTTP authentication is required in web application use below code.

String url = "Application Url";

WebClient webClient = new WebClient();

DefaultCredentialsProvider credential = new DefaultCredentialsProvider();

//Set some example credentials

credential.addCredentials("UserName", "Passeord");

webClient.setCredentialsProvider(credential);

HtmlPage htmlPage = webClient.getPage(url);

//verify response

Assert.assertEquals(200,htmlPage.getWebResponse().getStatusCode());

Assert.assertEquals("OK",htmlPage.getWebResponse().getStatusMessage());

Road to verify images using java webdriver

In this post I have explained that how to verify images in webdriver using java. As webdriver does not provide direct any function to image verification, but we can verify images by taking two screen shots of whole web page using “TakesScreenshot” webdriver function, one at script creation time and another at execution time,

In below example I have created a sample script in which first I captured a Google home page screen shot and saved (GoogleInput.jpg) into my project, Another screen shot “GoogleOutput.jpg” captured of same page at test executing time and saved into project. I compared both images if they are not same then test will script fail.

Here is sample code for same

package com.test;

import java.awt.image.BufferedImage;

import java.awt.image.DataBuffer;

import java.io.File;

import java.io.IOException;

import java.util.concurrent.TimeUnit;

import javax.imageio.ImageIO;

import org.apache.commons.io.FileUtils;

import org.openqa.selenium.OutputType;

import org.openqa.selenium.TakesScreenshot;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.Assert;

import org.testng.annotations.AfterSuite;

import org.testng.annotations.BeforeSuite;

import org.testng.annotations.Test;

public class ImageComparison {

public WebDriver driver;

private String baseUrl;

@BeforeSuite

public void setUp() throws Exception {

driver = new FirefoxDriver();

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

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

}

@AfterSuite

public void tearDown() throws Exception {

driver.quit();

}

@Test

public void testImageComparison()

throws IOException, InterruptedException

{

driver.navigate().to(baseUrl);

File screenshot = ((TakesScreenshot)driver).

getScreenshotAs(OutputType.FILE);

Thread.sleep(3000);

FileUtils.copyFile(screenshot, new File("GoogleOutput.jpg"));

File fileInput = new File("GoogleInput.jpg");

File fileOutPut = new File("GoogleOutput.jpg");

BufferedImage bufileInput = ImageIO.read(fileInput);

DataBuffer dafileInput = bufileInput.getData().getDataBuffer();

int sizefileInput = dafileInput.getSize();

BufferedImage bufileOutPut = ImageIO.read(fileOutPut);

DataBuffer dafileOutPut = bufileOutPut.getData().getDataBuffer();

int sizefileOutPut = dafileOutPut.getSize();

Boolean matchFlag = true;

if(sizefileInput == sizefileOutPut) {

for(int j=0; j<sizefileInput; j++) {

if(dafileInput.getElem(j) != dafileOutPut.getElem(j)) {

matchFlag = false;

break;

}

else

matchFlag = false;

Assert.assertTrue(matchFlag, "Images are not same");

}

Road to handle http authentication in webdriver

One of my applications had Http authentication for security purpose and I had need to automate using webdriver. As we know http authentication is not a part of DOM object so we cannot handle it using webdriver. Here is approach to handle such type situation.

We need to pass http credential with URL to skip http popup authentication window. Below is URL format.

http://username:passwork@applicationURL

User above formatted URL in webdriver get method:

driver.get(“http://username:passwork@applicationURL”)

After using above approach, http authentication popup window disappear. But in Internet explorer, it raise error with message “wrong format url”. To accept same type url in internet explorer browser we need to add a DWORD value named exploere.exe and iexplore.exe with value data 0 in below registry.
To open registry, open "regeidt" from run command.

1. For all users of the program, set the value in the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_HTTP_USERNAME_PASSWORD_DISABLE

2. For the current user of the program only, set the value in the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_HTTP_USERNAME_PASSWORD_DISABLE

3. If you are using 64 bit machine, set the value in the following registry key. HKEY_CURRENT_USER\Software\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_HTTP_USERNAME_PASSWORD_DISABLE

Road to automate Html5 video with Webdriver (Selenium)

In this post I will show you how to automate HTML5 video. To automate this we will use java scripts function to control video. So here we use “document.getElementById("Video ID")” , it return the HTML 5 video object. Using this object we can simulate video. Following are some java script function to handle video.
1. Play video

document.getElementById("Video ID").play();

2. Pause video

document.getElementById("Video ID").pause() ;

3. To check video is paused or not use below code

document.getElementById("Video ID").Paused;

4. To increase volume

document.getElementById("Video ID").volume=0.5;

5. To reload video

document.getElementById("Video ID").load();

6. To replay from stating or forward and back playing video. You can set current playing time.

document.getElementById("Video ID").currentTime=0

document.getElementById("Video ID").currentTime=10

document.getElementById("Video ID").currentTime=20

7. To check video is muted.

document.getElementById("Video ID").muted

Example: here is example of Webdriver to automate html 5 video, I am using JavascriptExecutor class to execute java script code.

public class HtmlVideo {

public WebDriver driver;

@Test

public void testVideo() throws InterruptedException

{

driver = new FirefoxDriver();

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

driver.get("http://www.w3.org/2010/05/video/mediaevents.html");

JavascriptExecutor js = (JavascriptExecutor) driver;

//play video

js .executeScript("document.getElementById(\"video\").play()");

Thread.sleep(5000);

//pause playing video

js .executeScript("document.getElementById(\"video\").pause()");

//check video is paused

System.out.println(js .executeScript("document.getElementById(\"video\").paused"));

js .executeScript("document.getElementById(\"video\").play()");

// play video from starting

js .executeScript("document.getElementById(\"video\").currentTime=0");

Thread.sleep(5000);

//reload video

js .executeScript("document.getElementById(\"video\").load()");

}

Screen Recording (Video) of Java Webdriver script

Sauce lab provided screen capturing functionality to test scripts execution, I was looking same type functionality to work on local machine and came up across “Monte Media Library” java based library developed by Werner Randelshofer.. In this post I have described a way to capture screen cast/ Video recording of selenium/webdriver test script execution.

Step to implement Monte Media library to selenium/Webdriver test scripts.

1. Download “MonteScreenRecorder.jar” from link http://www.randelshofer.ch/monte/

2. Add this jar file to your selenium/webdriver eclipse project.

3. This jar file contain “ScreenRecorder” class, we need to create this class object by following way.

GraphicsConfiguration gc = GraphicsEnvironment

.getLocalGraphicsEnvironment()

.getDefaultScreenDevice()

.getDefaultConfiguration();

ScreenRecorder screenRecorder = new ScreenRecorder(gc,

new Format(MediaTypeKey, MediaType.FILE, MimeTypeKey, MIME_AVI),

new Format(MediaTypeKey, MediaType.VIDEO, EncodingKey, ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE,

CompressorNameKey, ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE,

DepthKey, 24, FrameRateKey, Rational.valueOf(15),

QualityKey, 1.0f, KeyFrameIntervalKey, 15 * 60),

new Format(MediaTypeKey, MediaType.VIDEO, EncodingKey, "black",

FrameRateKey, Rational.valueOf(30)),null);

4. Need to call “screenRecorder.start()” methods at starting of your test scripts and "screenRecorder.stop()” at the end of execution.

5. Below is complete test script example

package com.TestScripts;

import java.awt.*;

import java.io.File;

import org.monte.media.Format;

import org.monte.media.math.Rational;

import org.monte.screenrecorder.ScreenRecorder;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

import static org.monte.media.AudioFormatKeys.*;

import static org.monte.media.VideoFormatKeys.*;

public class VideoReord {

private ScreenRecorder screenRecorder;

public static void main(String[] args) throws Exception {

VideoReord videoReord = new VideoReord();

videoReord.startRecording();

WebDriver driver = new FirefoxDriver();

driver.get("http://www.google.com");

WebElement element = driver.findElement(By.name("q"));

element.sendKeys("testing");

element.submit();

System.out.println("Page title is: " +driver.getTitle());

driver.quit();

videoReord.stopRecording();

}

public void startRecording() throws Exception

{

GraphicsConfiguration gc = GraphicsEnvironment

.getLocalGraphicsEnvironment()

.getDefaultScreenDevice()

.getDefaultConfiguration();

this.screenRecorder = new ScreenRecorder(gc,

new Format(MediaTypeKey, MediaType.FILE, MimeTypeKey, MIME_AVI),

new Format(MediaTypeKey, MediaType.VIDEO, EncodingKey, ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE,

CompressorNameKey, ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE,

DepthKey, 24, FrameRateKey, Rational.valueOf(15),

QualityKey, 1.0f,

KeyFrameIntervalKey, 15 * 60),

new Format(MediaTypeKey, MediaType.VIDEO, EncodingKey, "black",

FrameRateKey, Rational.valueOf(30)),

null);

this.screenRecorder.start();

}

public void stopRecording() throws Exception

{

this.screenRecorder.stop();

}

6. After execution test script, video file is generated under “Video” folder of current user folder in Windows machine and “Movies” folder on Mac machine.

I am getting some comments for saving video in a desire location, I am going to update my post as Michael’s suggestion. Thanks again for his help.
If you need to save video file in desire location, then you need to override “createMovieFile” function of “ScreenRecorder” class class for creating a new folder and file. For this you need to create another class like “SpecializedScreenRecorder” and extend “ScreenRecorder” class as below:

package com.test;

import java.awt.AWTException;

import java.awt.GraphicsConfiguration;

import java.awt.Rectangle;

import java.io.File;

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.Date;

import org.monte.media.Format;

import org.monte.media.Registry;

import org.monte.screenrecorder.ScreenRecorder;

public class SpecializedScreenRecorder extends ScreenRecorder {

private String name;

public SpecializedScreenRecorder(GraphicsConfiguration cfg,

Rectangle captureArea, Format fileFormat, Format screenFormat,

Format mouseFormat, Format audioFormat, File movieFolder,

String name) throws IOException, AWTException {

super(cfg, captureArea, fileFormat, screenFormat, mouseFormat,

audioFormat, movieFolder);

this.name = name;

}

@Override

protected File createMovieFile(Format fileFormat) throws IOException {

if (!movieFolder.exists()) {

movieFolder.mkdirs();

} else if (!movieFolder.isDirectory()) {

throw new IOException("\"" + movieFolder + "\" is not a directory.");

}

SimpleDateFormat dateFormat = new SimpleDateFormat(

"yyyy-MM-dd HH.mm.ss");

return new File(movieFolder, name + "-" + dateFormat.format(new Date()) + "."

+ Registry.getInstance().getExtension(fileFormat));

}

Now you need to create object of “SpecializedScreenRecorder” instead of creating “Screen” class object.

package com.test;

import java.awt.*;

import java.io.File;

import org.monte.media.Format;

import org.monte.media.math.Rational;

import org.monte.screenrecorder.ScreenRecorder;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

import static org.monte.media.AudioFormatKeys.*;

import static org.monte.media.VideoFormatKeys.*;

public class VideoReord {

private ScreenRecorder screenRecorder;

public static void main(String[] args) throws Exception {

VideoReord videoReord = new VideoReord();

videoReord.startRecording();

WebDriver driver = new FirefoxDriver();

driver.get("http://www.google.com");

WebElement element = driver.findElement(By.name("q"));

element.sendKeys("testing");

element.submit();

System.out.println("Page title is: " + driver.getTitle());

driver.quit();

videoReord.stopRecording();

}

public void startRecording() throws Exception

{

File file = new File("D:\\Videos");

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

int width = screenSize.width;

int height = screenSize.height;

Rectangle captureSize = new Rectangle(0,0, width, height);

GraphicsConfiguration gc = GraphicsEnvironment

.getLocalGraphicsEnvironment()

.getDefaultScreenDevice()

.getDefaultConfiguration();

this.screenRecorder = new SpecializedScreenRecorder(gc, captureSize,

new Format(MediaTypeKey, MediaType.FILE, MimeTypeKey, MIME_AVI),

new Format(MediaTypeKey, MediaType.VIDEO, EncodingKey, ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE,

CompressorNameKey, ENCODING_AVI_TECHSMITH_SCREEN_CAPTURE,

DepthKey, 24, FrameRateKey, Rational.valueOf(15),

QualityKey, 1.0f,

KeyFrameIntervalKey, 15 * 60),

new Format(MediaTypeKey, MediaType.VIDEO, EncodingKey, "black",

FrameRateKey, Rational.valueOf(30)),

null, file, "MyVideo");

this.screenRecorder.start();

}

public void stopRecording() throws Exception

{

this.screenRecorder.stop();

}

Above code explanation: Create a File class object and pass path where you want to save your video

File file = new File("D:\\Videos");

Create dimension of your screen to capture video, I have created object for default screen.

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

int width = screenSize.width;

int height = screenSize.height;

Rectangle captureSize = new Rectangle(0,0, width, height);

Now Create object of “SpecializedScreenRecorder” and pass Rectangle object, File object, and file name as a last argument and rest are same.
Run your test, you will see that a video will generate under your desire location.

Road to verify PDF file text using java webdriver

In this post I will explain the procedure to verify PDF file content using java webdriver. As some time we need to verify content of web application pdf file, opened in browser.
Use below code in your test scripts to get pdf file content.

//get current urlpdf file url

URL url = new URL(driver.getCurrentUrl());

//create buffer reader object

BufferedInputStream fileToParse = new BufferedInputStream(url.openStream());

PDFParser pdfParser = new PDFParser(fileToParse);

pdfParser.parse();

//save pdf text into strong variable

String pdftxt = new PDFTextStripper().getText(pdfParser.getPDDocument());

//close PDFParser object

pdfParser.getPDDocument().close();

After applying above code, you can store all pdf file content into “pdftxt” string variable. Now you can verify string by giving in put. As if you want to verify “Selenium Or Webdiver” text. Use below code.

Assert.assertTrue(pdftxt.contains(“Selenium Or Webdiver”))

Hope this post will help to verify web application PDF content.

2. Download xmlrunner.py from below url: http://pypi.python.org/pypi/XmlTestRunner/0.16654

3. Download and install “setuptools 0.6c11” from below link: http://pypi.python.org/pypi/setuptools

4. Install selenium 2 in your system using command: > easy_install selenium

5. Selenium server file should be in machine

Set up and launching Selenium Grid:

1. Run below command in on your console to launch Grid hub console:

java -jar selenium-server-standalone-2.21.0.jar -host localhost -port 4444 -role hub

2. Open two console and run below command to launch and register node with Grid hub.

java -jar selenium-server-standalone-2.21.0.jar -host localhost -port 5555 -role webdriver -hub http://localhost:4444/grid/register -browser browserName=firefox,platform=WINDOWS

java -jar selenium-server-standalone-2.21.0.jar -host localhost -port 5556 -role webdriver -hub http://192.168.1.22:4444/grid/register -browser browserName=iexplore,platform=WINDOWS

Replace local host to system IP of Hob machine. If you want to launch node in different machine.

Test script::

Put “xmlrunner.py” downloaded file in your project and create a scripts as like below script.

from selenium import webdriver

import unittest

import sys

from xmlrunner import *

class Grid2(unittest.TestCase):

capabilities = None

def setUp(self):

self.driver = webdriver.Remote(desired_capabilities={

"browserName": browser,

"platform":platform,

"node":port

})

print "set up executed"

def test_example(self):

self.driver.get("http://www.google.com")

print "open google url"

self.assertEqual(self.driver.title, "Google")

print "verify title"

self.driver.find_element_by_id("gbqfq").clear()

self.driver.find_element_by_id("gbqfq").send_keys("testing")

print "enter text in serach field"

self.driver.find_element_by_id("gbqfb").click()

print "click on search button"

def tearDown(self):

self.driver.quit()

if __name__ == "__main__":

args = sys.argv

port = args[1]

platform = args[2]

browser = args[3]

suite = unittest.TestSuite()

suite.addTest(Grid2('test_example'))

runner = XMLTestRunner(file('results_ExampleTestCase_%s.xml' % (browser), "w"))

runner.run(suite)

Execution:

Open two consoles go to your test scripts project and run below command one by one.

python Grid2.py 5555 WINDOWS firefox

python Grid2.py 5556 WINDOWS iexplore

Where Grid2.py is created test script.
After execution two xml files are generated under project for each execution.

How to run java test scripts using Grid2

Prerequisites.

1. Java should be install and setup path in system.

2. Eclipse should be configured TestNG plugin

3. Download the selenium-server-standalone-version.jar from the below location.

4. TestNG jar file.

Steps to create and execute test scripts:

1. Launch Grid 2 console(Hub ) and Nodes using below commands:

Hub:

java -jar selenium-server-standalone-2.29.0.jar -host localhost -port 4444 -role hub

Nodes:

java -jar selenium-server-standalone-2.29.0.jar -host localhost -port 5555 -role webdriver -hub http://localhost:4444/grid/register -browser browserName=iexplore,platform=XP,version=8

java -jar selenium-server-standalone-2.29.0.jar -host localhost -port 5556 -role webdriver -hub http://localhost:4444/grid/register -browser browserName=firefox,platform=XP,version=13

2. Run test case parallel: This “WebDriverGrid2Test “ example will be run test case on firefox and internet explorer on version 8 and 13 respectively.

package com.test;

import java.net.MalformedURLException;

import java.net.URL;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.remote.DesiredCapabilities;

import org.openqa.selenium.remote.RemoteWebDriver;

import org.testng.annotations.AfterClass;

import org.testng.annotations.BeforeClass;

import org.testng.annotations.Parameters;

import org.testng.annotations.Test;

public class WebDriverGrid2Test {

public WebDriver driver;

@Parameters({"browser", "version", "os"})

@BeforeClass

public void setup(String browser, String version, String os) throws MalformedURLException, InterruptedException {

DesiredCapabilities capability=null;

capability = gridStting(browser, version, os);

driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);

driver.navigate().to("http://google.com");

}

@Test

public void testGoogleSearch2() throws InterruptedException{

Thread.sleep(3000);

WebElement search_input = driver.findElement(By.id("gbqfq"));

search_input.clear();

search_input.sendKeys("Testing");

WebElement search_button = driver.findElement(By.id("gbqfb"));

search_button.click();

}

@Test

public void testGoogleSearch1(){

WebElement search_input = driver.findElement(By.id("gbqfq"));

search_input.clear();

search_input.sendKeys("Testing");

WebElement search_button = driver.findElement(By.id("gbqfb"));

search_button.click();

}

@AfterClass

public void tearDown(){

driver.quit();

}

public DesiredCapabilities gridStting(String browser, String version, String os){

DesiredCapabilities capability=null;

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

System.out.println("Test scripts running on firefox");

capability= DesiredCapabilities.firefox();

capability.setBrowserName("firefox");

capability.setVersion(version);

}

if(browser.equals("iexplore")){

System.out.println("Test scripts running on iexplore");

capability= DesiredCapabilities.internetExplorer();

capability.setBrowserName("iexplore");

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

capability.setVersion(version);

}

if(os.equals("WINDOWS")){

capability.setPlatform(org.openqa.selenium.Platform.WINDOWS);

}

else if(os.equals("XP")){

capability.setPlatform(org.openqa.selenium.Platform.XP);

}

else if(os.equals("Linux")){

capability.setPlatform(org.openqa.selenium.Platform.LINUX);

}

else{

capability.setPlatform(org.openqa.selenium.Platform.ANY);

}

return capability;

}

3. We need to create TestNG file like as below “Suite.xml” file:

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

</classes>

</test>

</classes>

</test>

</suite>

4. Rigth click on Suite.xml file, select “Run As” and click on TestNG Suite options

5. Now test script is executed on both browser and version combination. execution log on eclipse look like as below:

Webdriver C# test scripts execution using Grid2

Nunit framework is not support parallel execution of driver test scripts using Grid. If we use MbUuit framework then we can accomplish parallel execution of test scripts against Grid2. For set up MbUnit you can see “MbUnit Framework”

Test scripts setup :

1. Add reference Gallio and MbUnit ddl file to your Webdriver project from installed Gallio folder.

2. Add below code in project’s “AssemblyInfo.cs” file.

using MbUnit.Framework;

[assembly:DegreeOfParallelism(2)]

[assembly:Parallelizable(TestScope.All)]

3. We need to add below code for MbUnit framework in test scripts.

using MbUnit.Framework;

add [Parallelizable] annotation on test case lavel ass I added in belowtest scripts.

4. I have created two test one “GridTest1.cs” file for internet explorer and “GridTest2.cs” file for firefox browser.

GrridTest1.cs

using System;

using System.Text;

using System.Text.RegularExpressions;

using System.Threading;

using MbUnit.Framework;

using OpenQA.Selenium;

using OpenQA.Selenium.Firefox;

using OpenQA.Selenium.Support.UI;

using OpenQA.Selenium.Remote;

namespace SmapleProject

{

[Parallelizable]

[TestFixture]

public class GridTest1

{

private IWebDriver driver;

private StringBuilder verificationErrors;

private string baseURL;

[SetUp]

public void SetupTest()

{

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities = DesiredCapabilities.InternetExplorer();

capabilities.SetCapability(CapabilityType.BrowserName, "iexplore");

capabilities.SetCapability(CapabilityType.Platform, new Platform(PlatformType.Windows));

capabilities.SetCapability(CapabilityType.Version, "9.0");

driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capabilities);

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

verificationErrors = new StringBuilder();

}

[TearDown]

public void TeardownTest()

{

driver.Quit();

}

[Test]

public void GoogleTest()

{

driver.Navigate().GoToUrl(baseURL + "/");

driver.FindElement(By.Id("gbqfq")).Clear();

driver.FindElement(By.Id("gbqfq")).SendKeys("Testing");

driver.FindElement(By.Id("gbqfb")).Click();

}

GridTest2.cs

using System;

using System.Text;

using System.Text.RegularExpressions;

using System.Threading;

using MbUnit.Framework;

using OpenQA.Selenium;

using OpenQA.Selenium.Firefox;

using OpenQA.Selenium.Support.UI;

using OpenQA.Selenium.Remote;

namespace SmapleProject

{

[Parallelizable]

[TestFixture]

public class GridTest2

{

private IWebDriver driver;

private StringBuilder verificationErrors;

private string baseURL;

[SetUp]

public void SetupTest()

{

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities = DesiredCapabilities.Firefox();

capabilities.SetCapability(CapabilityType.BrowserName, "firefox");

capabilities.SetCapability(CapabilityType.Platform, new Platform(PlatformType.Windows));

capabilities.SetCapability(CapabilityType.Version, "15.0");

driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capabilities);

//driver = new FirefoxDriver();

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

verificationErrors = new StringBuilder();

}

[TearDown]

public void TeardownTest()

{

driver.Quit();

}

[Test]

public void GoogleTest()

{

driver.Navigate().GoToUrl(baseURL + "/");

driver.FindElement(By.Id("gbqfq")).Clear();

driver.FindElement(By.Id("gbqfq")).SendKeys("Testing");

driver.FindElement(By.Id("gbqfb")).Click();

}

Launch Grid

1. Run below command in on your console to launch Grid hub console:

java -jar selenium-server-standalone-2.21.0.jar -host localhost -port 4444 -role hub

2. Open two console and run below command to launch and register node with Grid hub.

java -jar selenium-server-standalone-2.21.0.jar -host localhost -port 5555 -role webdriver -hub http://localhost:4444/grid/register -browser browserName=firefox,platform=WINDOWS

java -jar selenium-server-standalone-2.21.0.jar -host localhost -port 5556 -role webdriver -hub http://192.168.1.22:4444/grid/register -browser browserName=iexplore,platform=WINDOWS

Test Execution:
1. Build webdriver project.
2. Open Gallio Icarus console add created Webdriver project dll file.
