The Selenium Browser Automation Project

Selenium is an umbrella project for a range of tools and librariesthat enable and support the automation of web browsers.

It provides extensions to emulate user interaction with browsers,a distribution server for scaling browser allocation,and the infrastructure for implementations of theW3C WebDriver specificationthat lets you write interchangeable code for all major web browsers.

This project is made possible by volunteer contributorswho have put in thousands of hours of their own time,and made the source codefreely availablefor anyone to use, enjoy, and improve.

Selenium brings together browser vendors, engineers, and enthusiaststo further an open discussion around automation of the web platform.The project organisesan annual conferenceto teach and nurture the community.

At the core of Selenium isWebDriver,an interface to write instruction sets that can be run interchangeably in manybrowsers. Once you’ve installed everything, only a few lines of code get you insidea browser. You can find a more comprehensive example inWriting your first Selenium script
