selenium for automated testing

Getting Started with Selenium

A comprehensive guide to Selenium, the industry-standard open source testing framework.

Benefits of Selenium Testing

Automates browsers

Selenium automates browsers—specifically, the human interactions associated with them, such as navigating to pages, clicking on elements, and typing text into input fields.

Stay current

Each language binding and browser is actively being developed to stay current.

Works across browsers

Selenium works on every major browser, in every main software programming language, and with every major operating system.

Runs nearly everywhere

Selenium can run on a local computer, on a remote server, on a set of servers with Selenium Grid, or on a third-party cloud testing platform like Sauce Labs.

Allows customized testing

Selenium makes it possible to write your own tests once, and run them across several browsers.

Enables parallel testing

Selenium IDE allows developers to run multiple tests across multiple browsers and OS configurations at the same time. This helps to speed up testing and scale growing test suites.

Selenium testing

What is Selenium? 

Selenium is an indispensable open source testing framework that software development and QA teams rely on to run fast, repeatable tests across every major browser and operating system. Because it supports the most popular scripting languages, including Node.js, Java, Python, PHP, Ruby, and C#, developers, QAs, SDETs, and project managers can all write and review tests in the languages they already know, dramatically accelerating time to market.

Over more than twenty years, Selenium has evolved from a tool for driving a single browser into the standard protocol for programmatically interacting with browsers as a human would, complete with an in-browser record and playback tool (Selenium IDE) and a distributed computing grid for running tests in parallel (Selenium Grid). With Selenium 4, a single test script runs unmodified across different languages, operating systems, and browsers, making it the backbone of modern cross-browser testing.
