What is Selenium? 

Selenium is an open-source web browser automation tool. It allows programmers and users to create scripts in languages such as Java, Python, C#, and Ruby to automate tasks such as form filling, button clicking, page surfing, and data retrieval from websites.

Selenium comprises numerous components, including Selenium Grid, which allows you to test on multiple PCs and browsers simultaneously, and Selenium WebDriver, which will enable you to control browsers through code.

This post will go over several Selenium Interview Questions and Answers for Freshers and Experienced both . These questions assess your knowledge of Selenium and your ability to think critically and solve problems. 

Selenium Interview Questions and Answer for Freshers 

Here are the following Selenium Interview Questions and Answers for Beginners to prepare for their initial job career. 

  1. Why use Selenium for programming?

Automatic Selenium testing has these benefits:

  •  Selenium’s main virtue is that it’s freeware and can be used everywhere.
  • Selenium supports Java, Perl, Python, C#, Ruby, Groovy, and JavaScript. 
  • Selenium supports Windows, Mac OS X, Linux, and UNIX, among others. 
  • Selenium supports numerous systems. A customized Selenium testing suite can be created on any device and run on another. It’s simple to develop Windows test cases and run them on Linux.
  • Selenium supports numerous languages and frameworks. It can compile code with ANT or Maven. TestNG allows app testing and results. Jenkins, Hudson, and other open-source tools can enhance Continuous Integration (CI).
  1. What exactly does automatic testing imply?

Putting software to the test You may automate manual testing of an application or system while still producing detailed test results by using testing tools that allow you to develop scripts that can be executed repeatedly. 

  1. Explain Selenese. Explain the various Selenium commands.

The Selenium IDE allows you to write test code in a language known as Selenese. It’s a set of steps you do to test your website or system. Selenium Commands are divided into three categories:

  • Actions are the instructions that inform web applications what to do.
  • Accessors are commands allowing users to save values in user-defined variables.
  • Assertions allow you to compare the application’s current state to the desired state.
  1. Explain what a “locator” is and mention the types of commands present in Selenium.

A tracker is an address that instructs you on how to locate anything on a website. Selenium includes several locators for precisely and uniquely identifying web components.

  1. What is a Selenium exception test?

An exception test anticipates an exception being thrown within a test class. It expects a @Test annotation and the expected exception name in quotes.

  1. What exactly is Selenium WebDriver?

Selenium WebDriver, or Selenium 2, is a browser automation framework that takes commands and executes them on a computer. It has complete control over the browser because it can communicate with it directly. PHP, Python, Perl, Ruby, and C# are all supported by Selenium WebDriver.

  1. What exactly does it mean when Selenium WebDriver mentions an Object Repository?

The element locator information is stored in the object library so that it does not have to be hard-coded into the scripts. We created a property file (.properties) to keep all the element locators. This file serves as a repository for Selenium WebDriver objects.

  1. What exactly is Selenium WebDriver?

Selenium WebDriver is often a collection of activities described by an interface. On the other hand, browser-specific classes provide a means to achieve it by extending a class. AndroidDriver, ChromeDriver, FirefoxDriver, InternetExplorerDriver, SafariDriver, and others are among the application classes.

  1. Which of the following groups do WebDriver Application Programming Interfaces belong to in Selenium?

Selenium provides several WebDriver APIs, including the ones listed below:

  • iPhone Driver
  •  EventFiringWebDriver
  •  HTMLUnit Driver 
  • Opera Driver
  •  InternetExplorerDriver
  •  ChromeDriver 
  • Safari Driver.
  1. What programming languages does Selenium WebDiver support?

The various programming languages that Selenium WebDriver supports are as follows:

  • Java
  • #C
  • Python
  • Ruby
  • Perl
  • PHP

Selenium Interview Questions and Answer for Experienced 

Below listed Selenium Interview Questions and Answers are for people with three to five years of experience 

  1. Tell me how to stop Selenium IDE.

Pause handles test script errors. The pause icon in the upper right corner of the IDE lets the user stop at the line that caused the exception and switch to debug mode. This approach ensures that the test case doesn’t fail and enables the user to fix the mistake immediately.

  1.  What if Selenium can’t deal with pop-up windows in Windows?

Selenium doesn’t work with pop-ups because it automatically tests web apps. With AutoIT, Robot class, etc., Selenium can handle Windows pop-ups.

  1. Listeners for Selenium WebDriver?

Selenium WebDriver Listeners “listen” to Selenium code events. Listeners can tell you what happens before you click, before and after you move to an element, or when an exception is thrown, and the test fails. Selenium Automation Testing uses “listeners” to keep track of the order of events and take pictures of any problems. Later in a trial, debugging is straightforward. WebDriver Event receivers and TestNG use receivers.

  1. How do you use a WebDriver Listener?

There are two ways to put Webdriver Event Listeners in place:

There are several ways to keep track of Webdriver events with WebDriverEventListener. All Interface methods must be used.

With AbstractWebDriverEventListener, we can only use the methods we want.

  1. Why should TestNG be used with Selenium RC?

Selenium RC uses JUnit, but TestNG is more flexible and can be used in more situations. TestNG’s testing in parallel, testing based on data, and marking test methods help speed up and organize tests. TestNG gives JUnit better ways to report and log. Selenium RC and TestNG make it easier to test online apps.

  1. What are the claims about Selenium?
Selenium Interview Questions and Answer

Assertions in Selenium check how a test went. Assertions can prove that something is true. If not, the test will stop because of an assertion mistake. Assertions can be used to check the text of an element, the number of input fields, the way a page looks, and more. Org. junit.SeleniumWebDriver has ways of making assertions.JUnit/org. testing says, “Class is true.”TestNG’s claim.

  1. How do you use the Silk Test Tool?

Silk checking, which used to be called Segue Silk Test, simplifies testing for bugs and how well the software works. Micro Focus built it and took care of it. It checks GUIs on desktops, phones, and online. The tool scans apps on different platforms, including Windows, iOS, and Android. The 4Test coding language from Silk Testing lets customers automate testing by making test scripts that mimic how users interact with the app. Users can record and change test files with a GUI-based visual text editor.

  1. What is Testing.xml for? 

The TestNG system uses the XML setup file testng.xml. It makes test plans and scenarios and runs them. It describes test programs and how test methods, classes, and packages are set up. It lets you set up test data, listeners, reports, parallel processing, test order, and more. Users can choose test listeners and sets and whether or not to include test methods and classes in the testing.xml file. It puts together test methods, classes, and packages and runs them.

  1. What is Actions class ?

The Actions class is how the Selenium Python tools take control of web browsers. You can interact with page parts by moving your mouse over them, clicking on them, or typing. Most of the time, WebDriver and Actions are used together. WebDriver handles how browsers talk to each other.

  1. How does Page Factory work?

Selenium WebDriver uses the Page Factory design pattern to store web component objects. It adds to the Page Object Model design philosophy, which keeps all web components in one place. Annotations let web things be found and turned on at runtime. They also make the code simpler. This is done by separating the test code from the specifics of finding page elements. Page Factory needs a class for each web page and the @FindBy annotation to find web parts. The class needs help with web components.


Selenium is a valuable technology software testers and coders use worldwide to automate web application testing. It is now the greatest option for testing online apps because it supports many computer languages, tests across browsers, and works with dynamic web apps.
