Selenium was created by Sauce Labs co-founder Jason Huggins and it spawned the cloud-based automating testing category. This guide, developed by core project contributors Diego Molina and Titus Fortner, is designed to help you get the most out of the latest version of Selenium.
Upgrade to Selenium 4 to get the most out of your automated testing
The latest version of Selenium delivers a host of new features. This comprehensive guide will help you get the most out of them and give you tips on updating the tests you run on Sauce Labs.
How to upgrade to Selenium 4
This article will help you go through the steps to upgrade your project dependencies and understand the major deprecations and changes the version upgrade brings.
New features for Firefox
Selenium 4 exposes a few new features that can be used with Firefox, such as installing/uninstalling add-ons, changing browser preferences mid-session, or taking full page screenshots for debugging.
New window & tab utilities
Does your test require opening a new tab or window? Selenium 4 includes a new command to make sure your automation script handles this without any unexpected results.
Relative locators
A new way of locating elements by using natural language terms such as “above”, “below”, “left of”, “right of”, and “near”. Think of them as a way to locate elements based on the visual placement on the page.
BiDirectional APIs
Bidirectional APIs in Selenium 4 will allow you to intercept network requests, mock backends, perform basic authentication, view the console logs, and more.
Updates to Selenium Grid
Selenium Grid 4 has been rewritten from scratch to take advantage of modern infrastructure features such as Docker and distributed tracing. You can now also extend local Grid capabilities using Sauce to Go.
