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.
