In this article, you will learn the differentiation between selenium 3 and selenium 4.
What is selenium 3?
The core (WebDriver + Selenium RC) is removed from the selenium 3 but it supports selenium Rc indirectly with the help of the back-end WebDriver. Selenium has become the W3C standard. W3C stands for world wide web consortium. It is the much-needed software testing tool for web and mobile applications. The vendors of the browser are providing their own WebDriver implementation. Therefore, they are tightly coupled with the browser for giving a better testing experience. Modern browsers are also introduced with WebDrivers. It uses the Appium tool for mobile automation testing.
What is selenium 4?
Selenium 4 has the Beta 1 version as the latest version with the new features of selenium that was released on the 15th February 2021. It has many advanced features such as selenium grid, W3C compliance, advanced IDE, new APIs, and many more. The features of selenium 4 are:
- Selenium WebDriver: It is a free and open-source that permits the creation of robust browser-based regression test cases and suites. It scales and distributes these test cases in multiple environments. It also permits you to interact with the browser just like a real user.
- Selenium IDE: It is an add-on on Chrome and Firefox. It simply records and playbacks the user interactions with the browser.
- Selenium Grid: It permits you to save time by distributing and running test cases on multiple browsers, operating systems, and machines. It enables you to manage multiple environments from the central point.

In selenium 3, the chrome driver extends directly to the RC driver. |
In selenium 4, the extends the class of the driver which has some predefined methods to access the dev tool. |
|
It has JSON wire protocol as a major mode of communication between the test code and the browser. |
The selenium 4 uses the WebDriver W3C protocol. |
|
The most difficult part for the tester in selenium 3 is the tester always needs to start from the hub and node jars each time to perform the automation testing on the Grid. |
The most interesting part of selenium 4 is it overcomes this problem to start from the hub and node to initiate the testing on the Grid. |
