Are you worried about the Selenium interview questions you’ll face because you have an important interview coming up?

To help you comprehend the depth of the questions and approach them with confidence, we have created this most popular Selenium interview questions and answers guide. These days web apps are on the rise. Web app testing is a necessity that will only increase as demand for them rises. That is where Selenium comes into action. Selenium is one of the frequently employed automated testing tools that makes sure the web application is functioning flawlessly. If testing were to be done manually, it would take a lot of man hours and cost more money.

Further, since they are manual, they are prone to errors. Since manual testing is ineffective over the long term, automated testing like Selenium is becoming more popular in the sector. This blog is for you if you want to work in automated testing and are getting ready for a Selenium interview.

We’ll go over the most typical Selenium interview questions in this blog. These are both Selenium interview questions for experienced candidates as well as beginners.

Page Object Model Interview Questions and answer for Experienced Automation Tester

What are OOPS concepts that developers apply in an automation framework?

This question may come up frequently in interviews to test your understanding of Java’s Object-Oriented Programming (OOPS) concepts. The four OOPS principles that programmers can use in an automation framework are an impressive response to this query. Describe each tenet and its function in automated testing.

Example response: Inheritance, Polymorphism, Encapsulation, and Abstraction are the four guiding principles of OOPs. A child class inherits a parent class’s properties under the inheritance mechanism. This makes it simple to reuse a base class’s methods in a subclass. To hide the data of one class from another, developers use encapsulation to combine code and data into a single unit. In Polymorphism, we have method overriding and method overloading. Combining the two enables us to carry out a single task in a variety of ways. With abstraction, we only display the essential information.

In different ways, developers frequently use inheritance, polymorphism, and encapsulation in Selenium testing. With Inheritance, developers may ensure the reusability of a class. This makes it easier for them to avoid repeatedly writing the same initialization code. A POM project has a separate class for every page. A great example of encapsulation is keeping the data of one class separate from the data of another class. The Selenium WebDriver interface adheres to the Polymorphism concept of a single interface supporting multiple methods by supporting the numerous procedures of various browsers.

In-Depth Questions

As a Selenium developer, you may be asked the following probing questions by hiring managers to determine your strengths and skills that enable you to complete a variety of tasks:

Questions About Background And Experience

In order to gauge your skills and understand your work experience and educational background, interviewers may ask you the following background and experience questions during your interview:

What is a Page Object Model?Page Object Model is a design pattern in Selenium, that is also used for enhancing test maintenance and reducing code duplication. Page Object Model is used in a framework like Data-Driven, Modular, Hybrid Framework, etc.POM is a class that is also used for serving as an interface to a page of our AUT(Application Under Test).

  • Code Resuability – POM can achieve code reusability by writing code and using in different tests.
  • Code Maintainability – POM acts as a Clean Separation between Tests Code and Page Specifics Code like Layout, Locators, which helps in maintaining code.
  • Object Repository – POM helps in defined like Java Class.The pages can be defined in an interface like members.
  • Readability – POM can help in improving readability by clean separation through Test Code and Page Specific Code.

    Q.1) Why pick Selenium over other automated testing tools?

    Selenium is open-source. Compared to other automated tools on the market, it is very simple to adapt. Due to this, many businesses chose Selenium automated testing over other conventional techniques.

    Refer to Selenium’s primary characteristics to comprehend its enormous adaptability.

    Key attribute Description
    Open Source Platform It is freeware and portable. There are no direct costs involved with Selenium. It can be downloaded for free and gets community-based support.
    Language Support Supports various languages such as Java, Python, Ruby, C# and more. It has its script, but that is not a limitation, as programmers can work with any language.
    Browser support There is a support across multiple browsers such as Chrome, Firefox,Internet Explorer, Opera and more. It becomes useful for programmers while testing.
    Operating Systems Support It can be operated across multiple operating systems such as Windows, OS, Linux, etc.
    Device support Supports tests across devices, as the test can be implemented on Android, iPhone and Blackberry.
    Reusability and add-ons The programmers can use scripts that can be tested across multiple browsers. Multiple tests can be executed using Selenium, which covers almost all the aspects of functionality testing by implementing the add-on tools.
    Programming languages support It can be integrated with various programming languages and frameworks, such as ANT, Maven, Jenkins, Hudson, and more.

    Q. 2) Describe a few advantages Selenium has over programs like TestComplete and QTP. Also, what are the disadvantages?.

    Unlike TestComplete and QTP, Selenium does not require a license, making it more cost-effective. The online community offers massive support. Compared to TestComplete and QTP, the release cycles are shorter and the feedback is given faster. Further, Selenium works on Mac, Linux, and Windows as well.

    Contrarily, Selenium demands that a developer possess strong coding abilities. While QTP and TestComplete, respectively, require low to moderate levels of coding skills

    For information on the benefits and drawbacks of selenium, see the table below.

    Advantages Disadvantages
    Open- source software No reliable technical support.
    Supports various programming languages Only support web- based applications.
    Supporys multiple operating systems (Android, iOS, etc.) Takes more time test cases.
    Supports various browsers (Chrome, Firefox, Safar, Internet Explorer, etc.) Difficult to setup Test Environments
    Supports Parallel Test Execution Limited Testing Support
    Test cases can be implemented while the browser window is minimised. No built- in reporting facility
    Faster than other tools. No test tool integration for executing test management.

    Q. How have the various Selenium version upgrades changed things?

    There were only three tool suites available in Selenium v1, which consisted of the Selenium IDE, RC, and Grid. The Webdriver was missing. The Webdriver wasn’t introduced until Selenium v2, the second version of the testing software. Selenium RC was no longer utilized after this was finished.

    They are available on the market, but there is no support for them. The next version of Selenium is Selenium v3. It consists of Webdriver, IDE, and the Grid. It is currently in use. A newer version, Selenium v4, is also now available.

    Selenium IDE is mainly for recording and playing back. The Webdriver is a programming interface for testing dynamic web applications. The Grid is utilized to run tests on distant host machines.

    You must record and replay tests using the IDE. The Grid is used to deploy tests on isolated host machines, and a WebDriver is used to test live web applications using a programming interface.

    To understand the differences between various Selenium upgrades, see the table below.

    Selenium Version Description
    Selenium 1
    • Included 3 suite of tools
    • Selenium IDE, Selenium RC, Selenium Grid
    • No webdriver
    Selenium 2
    • Seleniium Webdriver
    • Selenium RC not in use.
    Selenium 3
    • Selenium IDE
    • Selenium Webdriver
    • Selenium Grid

    What is POM framework?

    The Page Object Model (POM) is a Selenium design pattern or framework that enables the creation of an object repository for the various web elements used throughout the application. To make things simpler, we create a class file for each web page in the Page Object Model framework.

    What is POM in Selenium interview questions?

    POM stands for Page Object Model. This design pattern is used to build an object repository for web UI elements. Each and every web page in the application needs to have a corresponding page class that searches the WebElements on that page and then performs operations on them.
