How Selenium reduce software testing time?

Why is Selenium automation testing vital for software industries?


As an increasing number of businesses go online to reach the greatest number of customers and simplify complex tasks, most businesses are beginning to build their websites. And the amount of coding generated for software development daily is very large. Testing such complex web applications is extremely difficult, resulting in it consuming more time for testing engineers to test the code manually developed by the software developer. The goal of software testing is to find flaws and errors in software applications. Software testing takes up more than half of the time spent on the software development lifecycle. The amount of time it takes to test the software depends on the algorithm, programming language, lines of code, function points, and external and internal interfaces. At the end of the day, it is the software application’s success rate that is going to control the business's growth.

Manual Testing and its challenges:

Manual testing refers to the process of testing software or applications without the use of test scripts or software automation tools. To identify flaws in software and ensure that it complies with the requirements and ensure that software behaves correctly. Manual tests must be run in each environment with a different data set, and the success/failure rate of each transaction must be recorded. A manual tester must take the role of an associate user and use the majority of the application's options before being automatically tested. Any new application should be manually tested first. Manual testing takes more time and effort. This led to the invention of Selenium (an automation testing tool).

How Manual testing is outperformed by automated testing?

Manual testing is beaten by automation testing. Because it is faster, requires less human resource commitment, is less likely to make mistakes, allows for frequent test running, and enables fast execution, regression testing, and functional testing.

Selenium as the first choice for Automation testing:

Selenium is becoming very popular and it is the first choice of automation testers, as well as organizations, for automating the testing of Web-based applications for both the graphical user interface (GUI) and functionality. Selenium can also be used as a unit testing tool for JavaScript, Groovy, Ruby, Perl, Python, Java, C, and PHP.

Selenium is a tool for creating automated tests and improving testing efficiency. It is a web-based application automation testing tool that is open-source. It runs in the web browser and is compatible with almost all browsers, including Google Chrome, Mozilla Firefox, Microsoft Internet Explorer, Opera, and Macintosh Safari. It works on all operating systems, including Linux, Windows, and Mac. It's a great tool for system functional testing as well as browser compatibility and relationship testing. It has a lot of power when compared to other automation tools on the market, and it's also very flexible and easy to use. Everything is now web-based, so it is becoming increasingly complex. This massive information platform and rapid release cycle require rapid site regeneration.

Selenium consists of numerous components which contain three major tools. Every one has a selected role in supporting the event of test automation for a web application.

  • Selenium IDE:
    Selenium IDE is a development environment for developing Selenium test cases. Selenium IDE is a Firefox plug-in that allows testers to record their action as they follow the workflow that they need to test.
  • Selenium RC:
    It is a Client-Server Architecture that receives the Selenium Commands from the editor and tests are carried out via browser. It generates more complex tests by utilizing the full power of programming languages such as Java, C, PHP, Groovy, Python, Ruby, and PERL.
  • Selenium Web Driver:
    Selenium Web Driver is the heir to Selenium RC that sends commands to the browser and retrieves results.
  • Selenium Grid:
    Selenium Grid is a tool used to run parallel tests across totally different machines and different browsers at an equal time which ends in decreased execution time.

Continuous Development of Selenium Suite

In February 2021 the first beta version was announced. The latest version has new capabilities added such as relative locator’s introduction, transitioning from JSON Wire Protocol to WebDriver W3C protocol, and a Chrome debugging feature.

Future scope for Selenium:

Software testing has evolved with the advancement of technology in websites, applications, and software over the last few years. Many testing challenges have been overcome thanks to the use of test tools that have automated the process. Furthermore, the use of tools like Selenium has improved the approach to manual testing by reducing the amount of time spent on repetitive test cases. DevOps and agile methodologies have been major contributory factors to the changed approach to testing since open-source innovation. Most companies are incorporating Selenium as the testing tool for their software testing processes. There will be a huge demand for testing engineers for the software as it is growing continuously.

AI technology has only recently begun to make inroads into the world of automation testing. However, there is no such thing as complete or 100 percent automation when it comes to AI technology. Even though, AI technology is still used in a variety of ways by automation platforms. The majority of these are designed to give testers more capabilities as they repeat tasks. Apart from that, test maintenance is an important aspect of AI-based automation that will have an impact on the testing industry.


Automatic testing is better than human testing for lowering the testing process time and increasing precision and accuracy because it systematizes the testing process of analysis, design, and coding of various scripts. In a very short period, the Selenium automation testing framework is gaining wide acceptance as a popular and successful model of website automated testing. It has great flexibility and extensibility. The main advantage of using the selenium tool is to eliminate the need for manual testing. it is a web-based automation framework that supports a variety of programming languages and platforms. It can save time and effort for developers and programmers.
