Know the promised features of Selenium 4

I think every expert in the testing Domain, is more familiar with Selenium. One of the best Open Source Automation Tools. The upgrade process of Selenium 4, has delayed just like Selenium 3.

Promised Features of Selenium 4

The selenium conference, happened at Bangalore, Simon Stewart, has announced the below changes, that supposed to happen in selenium 4.

Selenium 4 IDE TNG

The playback and Record feature of selenium online training is taken by a complete New level, with updated and advanced features. That Selenium used to guide chrome. But with the new version, selenium 4, It is a plugin, that accepts, you to operate Selenium in any Browser.

Users, now they can declare their own locator techniques. We have, a new CLI runner, which is based on Node JS, instead of the traditional HTML Depended CLI runner.

It has the capacity to execute, test cases, in a parallel and offer Date that have passed and failed in test cases, the time needed.

The new IDE operator is complete, depended on Web driver.

Web driver API has changed to W3C Standardized

Web Driver API is, not used in selenium, but in many Automation Tools. Mobile testing Tools, like appium, depend heavily, on testing mobile applications. The best chance that we see in the new version of selenium is Selenium 4. It is a Standardized, web driver API that is with Respect to W3C, standards.

This explains, that it will be Implemented across, much Different software, without any compatibility issues. In previous, when web testing was operated, by using Selenium 3. The Browser communication was operated with JSON, with a Wire Protocol, from local ends. That needs API decoding and encoding.

Not anymore, though with selenium 4, you don’t need to decode, and encode your API Request, by using W3C protocol.

Java Bindings were come backward, that are compatible when concentrated on W3C protocol. Not to mention, the guidance for Phantoms and opera were removed, since they are in web Driver Implementation, for those browsers, are not developed.

Mostly, due to W3C standards, of web driver. The release date of Selenium 4, has got postponed, but by keeping this, in mind the new features, It is worth waiting. If the specification is completed, the remaining Job will fall on the other hands of the browser vendors.

That who decides, on how they are implementing, the latest web driver API. This is more logical, since the Internal Design of browsers, is better to know by vendors.

Improved Grid

If you have stated worked with selenium, you have to configure with, some techniques, known as problems, that arise, when you try to set it up for the first time.

The selenium Grid Version 4, makes you free from the Installation worries. It accepts that you execute test cases, parallel or multiple browsers. The systems as well as operating systems. The main 2 elements, of the new selenium Grid, were.

Node

The test machine on, which you can execute, the test cases.

Hub

Server, acting as a central point to control, all other machines, that available in the network. Selenium Grid has only one hub, whose content is to, assign the test case execution, for specific Node.

Till version 3, testers faced as many as lot of Difficulties, when they Interact with nodes. But in the latest version, selenium 4, the process is as much easier. The moment, you initiate selenium Grid. It will act as, dual node, and Hub.

We have better, Docker Guidance and no chance of thread safety bugs. Latest selenium 4. The grid also allows the user to output logs, within a single line format in JSON.

Better UI

A simple and User-Friendly Interface, it has as many features, for every application. selenium training has done, more to update and improve its UI, in the latest version.

Selenium 4. The grid UI is more User-friendly, that have related Information, all about, the capacity to execute, test cases or some details, about Sessions that are running, etc.

Best Observability

Logging with request tracing and Hooks, improve, debugging and observability which is no longer for DevOps.

These are the best updates we can see in Selenium 4. In upcoming article, I will write more data on Selenium 4.
