Selenium 4 Tutorial:

LambdaTest’s Selenium 4 tutorial is covering every aspects of Selenium 4 testing with examples and best practices. Here you will learn basics, such as how to upgrade from Selenium 3 to Selenium 4, to some advanced concepts, such as Relative locators and Selenium Grid 4 for Distributed testing. Also will learn new features of Selenium 4, such as capturing screenshots of specific elements, opening a new tab or window on the browser, and new protocol adoptions.

Chapters:

Upgrading From Selenium 3 To Selenium 4?: In this chapter, learn in detail how to update Selenium 3 to Selenium 4 for Java binding. Also, learn how to upgrade while using different build tools such as Maven or Gradle and get comprehensive guidance for upgrading Selenium.
What’s New In Selenium 4 & What’s Being Deprecated? : Get all information about new implementations in Selenium 4, such as W3S protocol adaption, Optimized Selenium Grid, and Enhanced Selenium IDE. Also, learn what is deprecated for Selenium 4, such as DesiredCapabilites and FindsBy methods, etc.
Selenium 4 With Python: Selenium supports all major languages, such as Python, C#, Ruby, and JavaScript. In this chapter, learn how to install Selenium 4 for Python and the features of Python in Selenium 4, such as Relative locators, Browser manipulation, and Chrom DevTool protocol.
Selenium 4 Is Now W3C Compliant: JSON Wireframe protocol is retiring from Selenium 4, and they are adopting W3C protocol to learn in detail about the advantages and impact of these changes.
How To Use Selenium 4 Relative Locator? : Selenium 4 came with new features such as Relative Locators that allow constructing locators with reference and easily located constructors nearby. Get to know its different use cases with examples.
Selenium Grid 4 Tutorial For Distributed Testing: Selenium Grid 4 allows you to perform tests over different browsers, OS, and device combinations. It also enables parallel execution browser testing, reads up on various features of Selenium Grid 4 and how to download it, and runs a test on Selenium Grid 4 with best practices.
