Selenium Automation Testing: Step by Step Guide for 2023

Selenium the Most Popular Test Automation Tool; A Superlative Guide To Selenium Testing

Automation Testing | May 26th, 2022 | Arun Charles



The most important element in the software development lifecycle is testing, which has the primary goal of ensuring bug-free software that fulfills client requirements. Testing is taxing since it entails manually running test cases against a variety of apps in order to find problems and failures. But what if the testing process could be automated? That would break up the monotony, and Selenium accomplishes this.

Emergence of Selenium

Manual testing was tedious and uninteresting for Jason Huggins, an engineer at ThoughtWorks in Chicago. He created JavaScriptTestRunner, a JavaScript software for automating web application testing.

What actually is selenium?

Selenium is an open-source automated testing tool for testing web applications across a range of browsers. Selenium is the preferred technology for automating web application testing, functional regression automation, and creating and managing automated test suites.


Why Selenium is Most Widely Used Test Automation Tool?

  • Selenium is mostly written in JavaScript, hence is simple to use.
  • Selenium can test web apps in a variety of browsers, including Firefox, Chrome, Opera, and Safari.
  • Tests can be written in a variety of languages, including Java, Python, Perl, PHP, and Ruby.
  • Selenium is platform-agnostic, which means it can run on Windows, Linux, and Mac OS X.
  • Selenium may be used to manage tests with technologies like JUnit and TestNG.
  • Selenium can run on your own computer, a third-party cloud server, a server (through selenium remote), or a group of servers (with selenium grid).

The Selenium Toolset


Selenium Integrated Development Environment (IDE)

IDE typically records user interactions in the browser and exports them into a script that may be reused.


DE was created to make writing automation scripts easier. It’s a rapid prototype tool that developers without any programming experience may use.

Selenium Remote Control (RC)

Selenium RC is a Java server that allows you to write application tests in a variety of computer languages, including Java, C#, Perl, PHP, Python, and others.


The RC server takes orders from the user application and converts them into Selenium-Core JavaScript commands for the browser.

Selenium WebDriver

WebDriver communicates natively with browser applications and does not require a core engine like RC. WebDriver also supports a variety of programming languages, including Python, Ruby, PHP, and Perl, and may be linked with test management frameworks like TestNG and JUnit.
Selenium WebDriver has a straightforward and easy-to-understand architecture:


Selenium Grid

Selenium Grid enables the execution of tests in parallel across several browsers and operating systems.


Grid is extremely adaptable, and it connects with other suite components to allow for concurrent operation.

How to successfully integrate Selenium Testing Automation?

  • A clear understanding of the vision and testing scope
    • Outline your revenue model, expected user behavior with the application, and browser types before planning your testing strategy.
  • Choose a Programming Language for Test Automation That Is Appropriate
    • A very crucial step to consider is choosing a suitable programming language for building acceptance tests for your website or application. Consult your application development team to learn about their experiences and skills with a specific language.
  • Select a Text Editor That Is Appropriate
    • You must choose a suitable text editor for beginners, it is advisable to start with a simple text editor like Sublime Text.
  • Characteristics of an Effective Acceptance Test
    • New acceptance tests should be descriptive, self-contained, atomic, work with a test runner, and be version controlled.
  • Develop it as robot and human-friendly
  • It’s critical to stick to a simple testing architecture:

    • Simplify test code with setup and teardown operations.
    • Create a new spec file and store your tests in it.
    • Use simple tagging
      • Reporting – Junit, XML output (for robots) and screenshots, logs, and videos for humans)
  • Scaling
    • Cloud execution, continuous integration, and parallelization can help you grow automated testing.
