QAutomation News / By  Sumon Dey

Whenever we think of automating any web application, the first obvious name that comes to our mind is “Selenium”. It’s quite fascinating how the Selenium project has evolved over the years and has become the most popular one. At present, it is a de-facto standard for almost all kinds of web application automation – thanks to its volunteer maintainers, contributors, and the vibrant community surrounding it.

It does this with the help of its supported language bindings (written in Java, Python, C#, Ruby, JavaScript) and vendor-provided browser drivers. The browser drivers are standalone proxy servers to assist the language bindings to speak to the browsers (by exposing their internal automation proxy interface) and are available in the form of executable binary files (ChromeDriver, GeckoDriver, IEDriver, EdgeDriver).
