What are Selenium 4 features?
Selenium 4’s new features are improvements to the previous version of Selenium, which is referred to as Selenium 3. These new features include the following:
-WebDriver JSON Wire Protocol - WebDriver JSON Wire Protocol lets you use the Chrome Remote Interpreter (CRI) using the WebDriver API.
-Wait Class Improvements (e.g., for automatically checking for a page element, waiting until an element appears onscreen, etc.) - The wait class is an improvement over Selenium 3’s WebDriverWait class, which lets you make requests to a server and wait for certain conditions to be met before continuing with automated testing.
-Page Object Model - This model helps you create pages that have actions that can be reused in different tests.
