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.
