Selenium Interview Questions

Q.1What is selenium's function?

Selenium is a free open source programme that automates web browser interaction and, as a result, web application testing.

Users can access web or mobile applications using a variety of web browsers, including Chrome, Firefox, Safari, Internet Explorer, and others, as well as different versions of each web browser.

Checking the functionality, load, and performance of a web application on each web browser and their corresponding versions is a complex undertaking.

Q.2What does selenium imply?

Selenium is a suite of software tools for automating web application software testing.

Selenium works with a variety of web browsers and versions. Selenium is compatible with a variety of testing frameworks and operating systems.

Selenium is primarily utilised as a catalyst as a chemical, and Selenium software tools are similarly employed as catalysts for web application testing.

 

Q.3What is the best programming language for selenium?

The best programming language for selenium is Java.

Because Selenium was created in the Java programming language, that's why.

You will be able to comprehend and interact with Selenium internals, which are written in Java.

As a result, the programming language most suited for selenium is Java.

 

Q.4 What is the function of the selenium driver?

The programming language bindings that connect to Selenium WebDriver are referred to as Selenium drivers.

Selenium drivers are libraries for each programming language that Selenium supports. The Selenium Webdriver API is exposed to the supported programming language via the Selenium driver or library.

The programming languages and testing frameworks that are supported are as follows:

NUnit Haskell - C#
JUnit and TestNG are two Java testing frameworks.
Objective-C Perl WebdriverJS, WebdriverIO, NightwatchJS, NemoJS JavaScript
Behat + Mink - PHP
Robot framework R, Python - unittest, pyunit, py.test
RSpec, Test::Unit, Ruby
For example, the Selenium Webdriver API in C# will allow you to control Selenium from a C# programme or test case.

 

Q.5What is the major application of selenium?

Selenium is mostly used to test web applications across several browsers and versions.

Selenium is a collection of cross-browser testing tools.

Selenium, according to its creators, automates browsers.

Popular web browsers include Chrome, Firefox, Internet Explorer, Safari, and others.

There are several versions of each web browser.

As a result, testing across many browsers and versions is a complex undertaking, and automating it minimises testing time and effort.

Selenium is mostly used for online and mobile application automation testing. 

 

Q.6In selenium, what is TestNG?

Selenium's TestNG is used to generate reports on the many tests that it runs. Selenium is a tool that automates the testing of web browser applications.

Both TestNG and Selenium are integrated to conduct automated tests for online and mobile applications, merging several tests into test suites and delivering complete test results in a variety of forms, including HTML.

TestNG is a Selenium plugin that makes it easier to generate Selenium test reports.

 

Q.7What is selenium and what does it do?

Selenium is a tool for automating tests. Selenium automates web application testing across numerous web browsers and versions of web browsers.

Selenium is the most common web application testing tool since it is open source and hence very popular in the open source community.

 

Q.8Do you think it's better to use Selenium with Java or C#?

Because Selenium was created in the Java programming language, it is better with Java.

Selenium is better integrated with Java, and software testing specialists that are familiar with Java can pick up Selenium rapidly.

Selenium supports a variety of Java frameworks.

 

Q.9Is Selenium with Python a good combination?

Yes, Selenium with Python adds the ability to automate web application testing to the Python programming language.

Selenium is an open source web application testing tool that tests web applications against a variety of web browsers and versions, such as Chrome, Firefox, Safari, and others.

Web applications written in the Python programming language can be evaluated in a variety of browsers and versions, including Chrome, Firefox, Safari, and others.

 

Q.10Under Selenium Grid, what is the default maximum number of browsers that can operate in parallel on a node?

a total of 5 browsers
What are the fundamentals of selenium?
Selenium Web Driver is a middleman that accepts test cases written in various programming languages such as C#, PHP, Python, and others and executes them on web browsers according to setup.

Selenium can test web applications in a variety of browsers and versions, including Chrome, Firefox, Safari, and others.

Selenium supports a variety of programming languages through several "drivers" or libraries that link to the Selenium API.

 

Q.12What are the benefits of a linear software testing framework?

The following are some of the benefits of using a linear framework for software testing:

1. Automation knowledge is not required because we will only be using the 'Record' and 'Playback' features.

2. Test scripts are simple to write and take a short amount of time to complete.

3. Because the scripts are written in a linear format, understanding the flow is quite simple.

 

Q.13Can you tell me about the types of tests you've automated?

The main focus is on automating test cases in order to do regression, smoke, and sanity testing.

The tests are sometimes depending on the project and the estimated test time, with an emphasis on End to End testing.

 

Q.14How do I create an Edge browser session using the right syntax? 

WebDriver driver = new EdgeDriver() is the right form for creating an Edge browser session.

 

Q.15In a day, how many test cases have you automated?

This is entirely dependent on the complexity and length of the test case scenario. In a single day, I've automated 4-5 test scenarios with a low level of complexity.

However, there are instances when only two or fewer test cases are run in a day, resulting in a high level of complexity.

 

Q.16Which domain is served by a web application?

B2C or e-commerce websites, B2B or trading websites, and organisational internal needs are all served by this web application.

 

Q.17What do you mean when you say "framework"?

A framework can be defined as a set of rules or best practises that can be implemented in a methodical manner to accomplish desired outcomes.

It provides a variety of automation frameworks, such as

Data Driven Testing Framework, Keyword Driven Testing Framework, and Hybrid Testing Framework are all examples of testing frameworks.

 

Q.18 Is Selenium a cost-free programme?

Yes, Selenium is an open source tool for testing web applications against different web browsers and versions, such as Chrome, Firefox, Safari, and others.

You do not have to pay a licence fee to use the tool. The tool does not have a licence charge or a usage limit.

The only cost associated with Selenium is the time and money invested learning and evaluating the tool.

 

Q.19In Selenium, which object prototype is utilised to extend Selenium?

PageBot is a prototype object.

 

Q.20Have you ever designed a Framework before?

Following are some situations that can be used in response to the interview question:

1. If you're a beginner: If you're a beginner, you can clearly say "No,

I didn't get the chance to build a framework from the ground up. However, I made advantage of the framework that is already in place. Using the current framework, I primarily contributed to the creation of test cases.

2. In this example, you are a beginning with a decent understanding of framework creation: "Yes, I was active in designing framework along with other automation testers in my organisation," you can begin.

3. If you're a seasoned tester, consider the following: "Yes, I have constructed framework from the ground up," you can say as an experienced professional. My previous organisation did not have any automation processes."
