Top Selenium Interview Questions and Answers

Top Selenium Interview Questions and Answers

1. What is Selenium?

Selenium is a suite of software tools to automate web browsers across many platforms (Different Operation Systems like MS Windows, Linux Macintosh etc.). It was launched in 2004, and it is open source Test Tool suite.

2. What is Selenium 2.0?

Web testing tools Selenium RC and WebDriver are consolidated in single tool in Selenium 2.0

Selenium 1.0 + WebDriver = Selenium 2.0

3. What is Selenium WebDriver?

Selenium WebDriver is a tool for writing automated tests of websites. It is an API name and aims to mimic the behavior of a real user, and as such interacts with the HTML of the application. Selenium WebDriver is the successor of Selenium Remote Control which has been officially deprecated.

4. What is cost of WebDriver, is this commercial or open source?

Selenium is an open source and free of cost.

5. How you specify browser configurations with Selenium 2.0?

Following driver classes are used for browser configuration










6. How is Selenium 2.0 configuration different than Selenium 1.0?

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.

7. Can you show me one code example of setting Selenium 2.0?

Below is example
WebDriver driver = new FirefoxDriver();
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();

8. Which web driver implementation is fastest?

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.

9. What all different element locators are available with Selenium 2.0?

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. className (“CalssName”));

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

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

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

26. How to verify PDF content using selenium 2.0?

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());
PDFParserPDFParser = newPDFParser(fileToParse);

//savePDF text into strong variable
StringPDFtxt = newPDFTextStripper().getText(pdfParser.getPDDocument());

//closePDFParser object
After applying above code, you can store allPDF file content into “pdftxt” string variable. Now
you can verify string by giving input. As if you want to verify “Selenium or WebDiver” text. Use
below code.

Assert.assertTrue(pdftxt.contains(“Selenium or WebDiver”))

27. How to verify response 200 code using selenium 2.0?

I will explain you 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 = “”;
WebClient webClient = new WebClient();
HtmlPage htmlPage = webClient.getPage(url);

//verify response
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”);

HtmlPage htmlPage = webClient.getPage(url);
//verify response

28. How to verify image using selenium 2.0?

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 “Takes Screenshot” 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.util.concurrent.TimeUnit;
import javax.imageio.ImageIO;
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;

public void setUp() throws Exception {
driver = new FirefoxDriver();
baseUrl = “”;
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

public void tearDown() throws Exception {

public void testImageComparison()
throws IOException, InterruptedException
File screenshot = ((TakesScreenshot)driver).
FileUtils.copyFile(screenshot, new File(“GoogleOutput.jpg”));
File fileInput = new File(“GoogleInput.jpg”);
File fileOutPut = new File(“GoogleOutput.jpg”);
BufferedImage bufileInput =;
DataBuffer dafileInput = bufileInput.getData().getDataBuffer();
int sizefileInput = dafileInput.getSize();
BufferedImage bufileOutPut =;
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;
matchFlag = false;
Assert.assertTrue(matchFlag, “Images are not same”);

29. How to handle http authentication in selenium 2.0?

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.


User above formatted URL in webdriver get method:

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.
For all users of the program, set the value in the following registry key:
For the current user of the program only, set the value in the following registry key:
If you are using 64 bit machine, set the value in the following registry key.
