Below are the top 7 reasons why it is suggested to use Selenium for automation testing by the QA teams.


One of the reasons for the popularity of the Selenium is its open-source availability. You can use the Selenium framework without paying any cost. many such companies provide automation testing tools and frameworks.

But they are not in a financial position they can provide free of cost access to their tools. In this scene, Selenium comes into the limelight among the automation testing teams.

The user gets almost all the necessary features required for automation testing free in the Selenium package. This saves a lot of testing costs that can be used in some productive works of their organization.

Apart from this, there are very active members of the community who strive to help engineers, as well as developers, automate a wide array of features and functionalities of a web browser.

Since Selenium is an open-source framework for automation testing, it allows you to customize your code for better management and improve the functionality of predefined functions and classes.

Language and Framework Support

The multi-language support feature of Selenium makes this tool a very popular choice among the testing team. Whenever we want to choose an automation testing tool, the first question that pops into your mind is about language support.

Is that specific tool compatible with our known programming language or not? Selenium eliminates this kind of issue as you have to write a testing script in your own language, and the rest work will be done by the Selenium tool itself.

Selenium offers many language support to perform the automation testing process. The various programming languages Selenium supports are C#, Python, JavaScript, Ruby, and Pearl.

The testing team can use any of their preferred programming language to write the test scripts and then convert them into Selenium compatible course. This helps a lot to save the time of writing test scripts. This way, our web developers have the flexibility to work with the language of their choice, which eliminates the need for training and retraining staff.

Reusability and Integrations

Selenium allows the testing team to write testing scripts once and reuse them. These test scripts can be used for automation testing on multiple browsers and operating systems.

One of the twists of using Selenium for automation testing is that Selenium is not an all-in-one package for automation testing. It needs some other frameworks to get integrated with it. And it is highly capable of it.

For example, if you want to manage the test cases and generate and view the testing reports, you must integrate Selenium with TestNG and JUnit. Another example is if you want to perform image-based automation testing, you must integrate Selenium with Sikuli. All these integration features can be easily done with Selenium.

Ease of Implementation

Using Selenium is very easy for the automation testing community. It is due to the simple and user-friendly interface of the Selenium tools. The user-friendly interface of these tools helps to watch your testing scripts running and analyze all the processes.

Also, the huge and active community of Selenium is always ready to help you if you get stuck at any point in implementing Selenium for your automation testing.

Parallel Test Execution 

One of the main objectives of automation testing is to save time and effort and make the testing process more efficient and productive. Using the Selenium grid to perform automation testing allows you to run your tests parallelly.

You can run multiple tests simultaneously, which run parallel to save testing time. With cloud rates for cross-browser testing, you can test across hundreds of browsers in parallel using Selenium.

For instance, if you were to run a test case that takes 10 minutes to complete in parallel, it would only take 10 minutes to complete the task of testing a combination of 10 distinct browsers and devices. So, using the concept of parallel testing by using the selenium grid helps to test the browser on a large number of web browsers.
