Upgraded Features In Detail

Selenium being the talk of automation testing industry has released the Selenium 4 Alpha that is to be upgraded into the Selenium 4.0. The following features can be spotted in the Selenium 4 version;

1. Web Driver Changed To W3c (World Wide Web Consortium) Standardization:

The Selenium 4 has a change in standardization to W3C to encourage the compatibility across various software implementations of the WebDriver API. This change ensures that the communication does not require the encoding and decoding of API. This results in a more stable framework and reduces compatibility issues across various web browsers.

2. Improved Selenium Grid

The Selenium Grid has been improvised in terms of its UI and stability. The coding of the Selenium grid has been changed completely and the console of the grid has been restructured. This allows the execution of the test cases in parallel on multiple browsers and operating systems. Now, the Grid can serve the purpose of the Node and Hub.

The UI grid of Selenium 4 has been created to be more user friendly and has all the relevant information regarding the session’s capacity, run time and other such details. Another addition to the grid is the support for utilizing the Docker containers along with the grid server.

3. Friendly/ Relative Locators Introduced

Selenium provides multiple explicit locators such as id, XPath, etc… the new locator provides a way to locate the element by its position by concerning other elements such as above, below, to-left-of, to-right-of & near.

4. Support For Browsers

The existing support for Opera & PhantomJS is to be removed. Users who wish to test Opera can go for Chrome and users who wish to test PhanthomJS, can go for Chrome or Firefox in the headless mode. The HTML unit is no more default on Selenium server.
