What is selenium, its advantages and brief history?

What is selenium?

Selenium is a free, open-source suite for testing web application automation across browsers and platforms. However, Selenium is focused on automating web-based applications. Tests performed using selenium are commonly referred to as selenium tests. Note that Selenium only supports testing web applications. It cannot be used for testing desktop or mobile applications. Check here Free Current Affairs Magazine-  DOWNLOAD NOW  

History of selenium

Selenium was the first tool that allowed users to control their browsers using any language. Experts were able to automate a variety of processes, but there were many drawbacks, as JavaScript could not be used to automate testing for specific things. And as web applications grew in complexity, the limitations of tools began to increase. Soon, Google's Simon Stewart got fed up with Selenium limitations. He developed WebDriver because he needed a test tool that could communicate directly with the browser. A few years later Selenium was merged into WebDriver. This tool allowed the expert to perform automated testing in one tool, making it much more efficient.

Advantages of selenium

• Selenium is open source, so there are no licensing costs, which is a big advantage over other testing tools.
• Net programming language tests can be run on Windows, Mac, or Linux operating systems.
• Tests can be run in Mozilla Firefox, Internet Explorer, Google Chrome, Safari, and Opera browsers.
• Integrate with tools like TestNG and JUnit to manage test cases and generate reports Integrate with Maven, Jenkins, and Docker for continuous testing.

Drawbacks of selenium

• Cannot test desktop applications or other software, no guaranteed support for Selenium.
• Need to use customer community available Images cannot be tested.

 
 

• The need to integrate Selenium and Sikuli for image-based testing.
• No native reporting functionality.
• But you can solve this problem by integrating with frameworks like TestNG and JUnit.

Development of selenium

Many developers create Selenium because it is not a single tool, but a collection of tools. Jason Huggins, an engineer who worked at ThoughtWorks, was the first to realize that the web application he was working on required frequent testing. That's when he came up with Selenium. He found that iteratively testing applications manually was inefficient because it took a lot of time and effort. He created a JavaScript program that could automatically control browser actions, which he named Java Script Test Runner. This tool was later called Selenium.
