What is the differences between Selenium 3 and Selenium 4 architecture?
Hey Tobi,
In the Selenium WebDriver Architecture of Selenium 4, the use of WebDriver JSON Wire Protocol has been replaced with a new protocol called the Remote Control Protocol (RCP). This protocol is based on the HTTP wire protocol and looks very similar to it.
The other major difference between Selenium 3 and Selenium 4 is that in Selenium 4, you’ll need to use different language bindings for different browsers. For example, if you’re working on a test case in Java and want to access the Google Chrome browser, you’ll use the Selenium-Webdriver Client API for Google Chrome. If you want to work with Mozilla Firefox instead, you’ll use the Selenium-Webdriver Client API for Mozilla Firefox.
Hope it helps!

The upgrade made on selenium 3 to selenium 4 was mainly done to include W3C (World Wide Web Consortium) an international community that develops web standards. Besides, there are so many interesting features that make selenium 4 a better option to pursue in comparison to selenium 3. Some of these include:
-
Selenium IDE offers support for rapid test development which means it does not require extensive programming knowledge.
-
WebDriver offers a friendly and flexible API for browser automation, and that too in most major programming languages.
-
Selenium Grid on Selenium 4 makes it possible to distribute and run your tests on more than one machine.
