What is New in Selenium 4

Selenium is a popular software automation-testing tool used by many top companies for web application testing and it provides a record/playback tool for debugging without the need for learning a test scripting language (Selenium IDE).

Selenium 4 Alpha version had released on April 28, 2019 and has more features as promised for improving the testing performance. Some of them explained here for the better understanding.

Selenium 4 IDE TNG

The record and play feature was improved with its rich features in Selenium 4 by a new plug-in to support all web browsers. In previous versions’ selenium supported only on chrome. In addition, it allows the user to implement their own locator strategy.

New CLI runner introduced for working on Node.js instead of HTML based CLI runner. In this version, the test engineer can execute the test cases in parallel and give about the validation and time estimation, etc. Selenium 4 IDE runners are the all-new feature and it is completely web driver-oriented.

W3C standardized WebDriver API

Selenium 4 has become standardized as per the W3C standards therewith it can now implement on any software applications without any compatibility issues. Previously it was done through JSON wire protocol from the local device in which it needs to encode and decode the API every time for the code protection.
Java bindings will be at the back while the focus on W3C protocols and no need of encryption process for testing the code. This surely makes easy to use for developers with its logical approach if they know thoroughly about the internal architecture of a browser.

Improved Grid

Many challenges were there in previous versions like configuration, and issues raised when installing it for the first time. Selenium grid made the installation work simpler and it allows test engineers to use test cases simultaneously in multiple browsers and operating systems. There are two main elements involved in Selenium Grid to simplify this process as below

Node: The device or machine in which we execute the test cases
Hub: The central server that control all the machines of a network. Selenium Grid has a single hub to allocate the test cases to a particular node.

In previous versions, many difficulties faced when connecting the nodes with a hub. In this version, it becomes easy. Once we boot up the Selenium Grid it will start acting like both a node and a hub. Docker support also there to avoid thread-safety errors. Moreover, it also allows the user to output logs in single line format in JSON

Improved User Interface

Easy to Use: EMR takes care of node provisioning, Hadoop configuration, Infrastructure setup, and cluster tuning as it launches the clusters in a minute. It allows collaboration over the process and explores, process, visualize the data in easy like notebook format.

Improved Analysis

Selenium 4 is updated with features like logging, debugging, hooks, and observation, etc. This improved feature helps the tester equipped with more data required to share with the development team for fixing the bugs.

Clear Documentation

Selenium 4 comes with the detailed documentation for easy understanding, following, and implementing the test cases. The tester can perform through self-learning about Selenium 4 for fixing some common mistakes.

Final Note:

The alpha version of Selenium 4 becomes easier with the much-improved features like Backend APIs, Selenium Grid, and the major advantage of W3C Standardization. Moreover, test cases were done in previous versions will not be affected on the scripts. These new features will make more comfortable for the testers and add more value to the projects for sure.
