Selenium for Automation – Why do you need it

If you are looking for a tool to help with automating your web applications, Selenium for automation is a great option. It’s an open-source tool that can be used for both functional and regression test automation.

Selenium can be used across different browsers and operating systems, making it a versatile tool for your testing needs.


Selenium for Automation

Deciding Why you need Selenium

Selenium is a great tool for automating testing, but you need to decide why you need it before you can use it effectively. If you just want to automate some simple tests, Selenium may not be the right tool. But if you need to automate complex tests or tests that require a lot of data, Selenium is a great tool.

To use Selenium effectively, you need to understand how it works and what it can do.

Selenium is a powerful tool, but it has its limitations. If you understand those limitations, you can use Selenium to its full potential.

What is Selenium?

Selenium is a lightweight framework for web application testing. Selenium offers a record/playback tool for creating tests without learning a test scripting language (Selenium IDE).

It also provides a test domain-specific language (Selenese) to write tests in several popular programming languages, including JAVA, C#, Groovy, Perl, PHP, Python, and Ruby.

The test can then be run against the most modern web browsers. Is an open-source software, released under the Apache 2.0 license, and can be downloaded and used without charge.

A list of tools:

  • WebDriver
  • Selenium Grid
  • Selenium Remote Control (RC)
  • Selenium Integrated Development Environment (IDE)

Why Selenium is the best tool for the job?

When it comes to automated testing, Selenium is the best tool for the job. It is an open-source testing tool that can be used to test web applications.

Selenium can be used to test web applications on different browsers, such as Firefox, Chrome, and IE. It can also be used to test web applications on different operating systems, such as Windows, Linux, and Mac.

It is a very versatile testing tool that can be used to test web applications of all types.

Is a free and open source

There are several reasons why Selenium is the best tool for automating web applications.

First, it is free and open source, so there are no licensing costs associated with using it. Second, Selenium has excellent support for a wide variety of browsers and operating systems. Third, Selenium is very extensible and there are a wide variety of plugins and extensions available for it.

Finally, Selenium has great documentation and a large and active community of users.

Has great documentation

Selenium is the best tool for automation because it has great documentation. The documentation is clear and concise, and it covers all the features of Selenium.

There is also a large community of users who can provide support and advice.

Selenium is constantly being updated, so it is always up to date with the latest technology.

Supports many browsers

Selenium is the best tool for automation because it supports many browsers. Selenium can automate tasks across different browsers, including Firefox, Chrome, and Safari.

This makes it the ideal tool for automating web-based tasks. Selenium is also very efficient and can save you a lot of time when compared to other automation tools.

Has a large and active community

It has a large and active community, which makes it easy to find help and support when needed.

Selenium is also constantly being improved and updated, so it’s a tool that will continue to be relevant for years to come.


By default, Selenium WebDriver helps the testers in turning the comprehensive test cases. Additionally, it has proved as a better option how it can deal with several issues while running the automation tests.

For instance, it enables test automation using a stable and more current HTTP protocol instead of using the less reliable JavaScript (Selenium IDE & RC)

Selenium Grid

Selenium Grid is software that allows you to test your code on different configurations. It lets run your tests on different environments, on different machines, and different operating systems all at the same time.


  • Runs multiple browsers and environment tests simultaneously.
  • Saves a lot of time.
  • Uses the Hub-and-Nodes model.
  • The hub is a central command center.
  • Each node is connected to it.

Selenium Remote Control (Selenium RC)

For a long time, Selenium RC was the premier testing framework of the entire Selenium project. It’s the first automated web testing tool that allows users to use their preferred programming language. RC can now cover the following programming languages as of variant 2.25.0:

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

Selenium IDE

The Selenium Integrated Development Environment (IDE) is the most basic and easiest-to-understand framework in the Selenium package.

It is a Firefox plugin that you can install just like any other plugin. Selenium IDE, on the other hand, is used as a design tool due to its simple structure.

If you want to generate more sophisticated test cases, you must use Selenium RC or WebDriver.

What types of tests can Selenium be used for?

Selenium is commonly used to automate the following types of tests:

Compatibility Testing:

Done by QA/Testing professionals to ensure that web apps meet performance benchmarks. Ensuring front-end responsiveness, for instance, is an important aspect to test when developing apps.

Performance Testing:

Series of tests that are documented so that a tester can easily verify the work on multiple browsers and browser versions to ensure that it meets performance benchmarks.

Integration Testing:

Done by programmers to check if the various modules/functions/codes they’ve been working on individually are functioning/working when joined together as one. Parallel Test Calculator, for instance, has two separate functions—one in the front end to accept what’s on the webpage and then another in the backend to create a response based on the data that’s entered. The testers should be able to validate that data/response can be sent to the front end after it’s been sent to the backend.

System Testing:

Also known as ‘software inspection’, automated coverage testing maximizes test coverage and evaluates the completeness of test case execution.

This type of testing typically revolves around: verifying all individual components of a software/application; and ensuring that the entire system is functional.

Automated testing could involve a scripted process that executes an application and captures (and stores) the outputs.

End-to-end Testing:

Testers/QA professionals are also responsible for this, usually from the perspective of the user. The goal is to ensure that all interactions on the web app are operational.

Regression Testing:

A series of tests are performed to ensure that newly developed features are compatible with the existing system.

Who Needs Selenium?

In short, everyone who cares about their web application needs to make sure it runs fast.

Part of the reason why Selenium is so relevant is its ability to be incorporated into any aspect of the software development cycle regardless of background.

Whether a quality assurance specialist or an engineer, anyone can use it to quickly test their code/app–even if it is only for simple debugging. And it’s got even more going for it! Because it can be used so easily and quickly, it will continue to grow in popularity with developers–making them more efficient and brilliant at their job.

In enterprise scenarios, testing with Selenium is generally the responsibility of quality assurance (QA) engineers. They are responsible for writing well-defined, non-flaky (i.e., deterministic), browser-based tests to maximize test coverage and accuracy, refactoring old test suites for the most recent versions of the project, and maintaining the test infrastructure

They’ll collaborate with your engineering team to map out a comprehensive set of tests and benchmarks for the final product. Their primary goal is to make sure that the project is efficient and as productive as possible (with the right test cases and benchmarks).

What do you need to get started with Selenium?

Selenium does not need to be “downloaded” like a piece of software. Even so, you will still need some of its elements to run tests on automated browser situations with your device.

Easily go to Automate Documentation to get a feel for it. Choose a language and/or framework with which you are familiar. Configure the required components and run a few sample tests by following the steps. In no time, you’ll have operational Selenium automation testing.
