Why is Selenium the Best Automated Testing Tool?

Mention automated web application testing in a conversation and the first thing you will hear will be Selenium. That is how popular Selenium has become. It is to automated testing what Google is to search engines. Selenium has 27.4% of the market share in testing web applications, making it an unbeatable leader in the field. In fact, Selenium certification can fetch you an average salary of USD 81k.

But what is it about Selenium that has given it this status? Why is it so popular? Is it just a hype? Does it really live up to the reputation? Let us find out!

Open Source

We start with the most apparent reason for its popularity. Selenium is a free, open-source software. Even though it was developed by ThoughtWorks for internal testing, it was later released for public use and that too without any licensing. Any organisation that is curious about Selenium just needs to download and install it to give it a try. This allows software companies to be more open-minded about giving Selenium a try. Once they do and see how superior Selenium is compared to the other testing tools, they invariably shift to using Selenium.

Multiple Language Support

Learning a new language is one of the major pain points while adopting a new testing tool. You won’t face this hurdle with Selenium. Even though Selenium has its own scripting language, Selenese, it is not mandatory to write your tests in Selenese. You can use Java, Python, PHP, Ruby, C# or Perl for this purpose. Every language also gets its dedicated framework in Selenium. During your Selenium training, you can concentrate entirely on how to use the tool, rather than splitting your focus between learning a new language as well as a tool.

Supported by Multiple Browsers and Operating Systems

In addition to supporting multiple languages, Selenium also supports multiple browsers and operating systems. When the web application is released for public use, it won’t be accessed from just one browser or OS. It is important that the application is tested for use on as many varieties of OS and browsers as possible. However, changing the testing tools for each browser or OS is unrealistic. You can create a test case in Selenium for one browser and run the same for another without changing anything. The same applies for testing in different OS as well.

Reduce Test Time

Selenium Grid lets you run multiple tests on different OS and browsers simultaneously. It does so using a simple hub-node architecture. Multiple computers are connected together. One of them acts as the hub, and the rest become the nodes. Each node is a combination of an OS and a browser. The hub controls the tests on all the nodes. So, not only does Selenium support multiple OS and browsers, but it also supports parallel testing on them.

Community Support

Since Selenium isn’t a licensed software, you don’t get dedicated customer support. What you do get, is a passionate community of like-minded people who are continually working towards supporting and improving Selenium. As soon as a fault is discovered, the community starts fixing it and rolls out an upgrade. Since the upgrade is developed by the community, for the community, it is easily understandable and doesn’t require special training. This makes Selenium cost-effective as well as resourceful.

Easy to Learn

You can learn Selenium with just a little help. There is a plethora of online tutorial available. Whenever you get a doubt, you can post it online, and other Selenium users will come to your rescue. Since you can create test cases in most of the major programming languages, you do not have to learn a new language. Even the interface is extremely user-friendly. All of this makes it easy to learn Selenium.

Easy Integration

No tool is perfect, and neither is Selenium. Selenium cannot perform image-based testing, continuous testing or generate reports. What makes Selenium truly great is that it has found a way to integrate other tools that make up for these shortcomings. For example, you can integrate it with Sikuli for image-based testing. JUnit and TestNG are used for managing the test cases and generating reports. Maven, Docker and Jenkins integrated with Selenium can be used to perform continuous testing.

Join the Selenium Workforce

Wouldn’t you like to become a part of this vibrant community and reap the benefits that it provides? Start your Selenium training right away by joining a reputed institution that provides industry-approved training. Such a certification will definitely boost your value as an employee, and make it easier for you to get that much-needed job or promotion.
