In Web Application Testing it is essential to address issues like website functionality, security, user interface, compatibility, and performance. Test Automation provides a framework to run tests with a combination of various forms of data to enhance test coverage.
Selenium is one of the many tools used for automated testing. But, along with the characteristic advantages of automated testing, Selenium has certain unique benefits that give it a competitive edge over others.
- Open Source: One of the most important benefits of Selenium is its Open Source Accessibility. As it is an open-source tool, anyone can download the source code and use it. It can also be refactored based on project requirements. This improves the functionality of predefined functions and classes. Selenium has turned into the most dependable web automation tool on account of the ease of developing test scripts to validate the functionality.
- Multi-Language Support: This must be the absolute and most imperative factor for any software skilled individual to get into the Automation Testing domain. The most common languages testers normally use for writing Selenium code are, C#, Java, PHP, Perl, Python, and Ruby. In most cases, enterprises may prefer to stick with the language already in use by testers and thereby eliminate the need for learning a new language. But in several instances, it is convenient to opt for a new language. Selenium is invaluable in such situations. For instance, if the team is new, or if the software is being revamped and the legacy language is now obsolete, Selenium allows the option to opt for a new and easier language for testing.

- Multi-Browser Support: Chrome, Firefox, Safari, Internet Explorer, Opera, and Edge are the most commonly used browsers worldwide and are compatible with Selenium scripts. One can create Test scripts and execute them in these browsers without any changes in the script. That means, it is not required to rewrite the scripts for every browser, just one script for all browsers, with the help of browser drivers.
- Platform Support: Yes, one more advantage we get with Selenium! We need not bother about the system configuration. Once we create test scripts on any operating system, they can be executed on any other operating system. For Example, if we create Selenium test scripts on the Windows platform, the same scripts can be executed on other platforms like Mac or Linux. This empowers QA Engineers/Testers to effectively write the scripts without paying much attention on the platform.
- Framework Availability: Frameworks are like templates. They provide a structure to your scripts and help in making code maintenance easy. Frameworks provide increased code re-usage, higher portability, reduced script maintenance cost, and higher code readability. There are different frameworks like Data Driven Framework, Keyword Driven Framework, Hybrid Framework, etc.
- Remote Control/Parallel Text Execution: Automated testing aims to save time and effort. Multiple test scripts should be executed in parallel, to reduce the test execution time. With the help of Selenium Grid, multiple scripts can be executed on remote machines. This is one of the most essential advantages of Selenium. Additionally, we can use Online Selenium Grids, for example, Lambda Test, which helps access to more than 2000 browser environments, over which we can run out tests and automate cross-browser testing. With the growing demand for testing deliverables, it is highly important to execute the test scripts quickly and efficiently.
- Flexibility: There are a wide variety of frameworks that supports Selenium when compared to other test automation tools in the same class. For example, Test management and Test controller activities (dependencies, grouping, etc.) are performed by other frameworks when we integrate (ex: TestNG, JUnit) with Selenium. Hence, it is more flexible and adaptable in terms of automation development and maintenance.
- Reusability: As we know, Selenium test scripts can be executed in multiple browsers and operating systems. Moreover, tests written in Selenium reduce a lot of manual efforts required in running them repeatably.
- Integrations: Selenium can be integrated with TestNG and Junit for managing test scripts and generating reports. For Continuous Integration testing, it can be integrated with CI/CD tools like Jenkins, Maven, Docker, etc. To perform image-based testing, the Sikuli tool is used to integrate with Selenium. Likewise, we can integrate many other tools with Selenium for better use.
- Regular Updates: Selenium is supported by an active community. The Selenium community regularly releases constant updates and upgrades. The finest part about having a community is that these updates and upgrades are ready to use and easy to understand. Selenium has got considerable support and recognition from various communities and vendors. This makes Selenium an Industry Standard Tool rather than being considered as only an open-source tool.
Because Selenium is a complete package of various automated testing solutions, businesses all over the world have started using it for testing the simplest as well as the most complex software applications. With its numerous advantages and easy-to-use features, Selenium proves to be one of the best automated testing tools for the IT industry.
