Explore Selenium 4.0 With New Changes

  • Post published:November 30, 2021

There is no limit to what can be achieved with the power of automation. Reducing manual intervention and minimising repetitive processes, all come under the umbrella of automation that companies have seized over the years. Just like that Selenium gives control to its users. As their motto dictates: “Latest version of Selenium automates browsers. That’s it! What you do with that power is entirely up to you.”

Selenium has been providing a range of tools and libraries, aiding web browser automation since 2002.

Over the years, Selenium has been the most preferred tool suite for automating web browser and web apps testing. The latest version of Selenium was announced back in 2018 and for almost 3 years they ran the beta version of Selenium 4. However, now they have finally released it as Selenium 4.0 and this is a great time to mention how it differs from the beta version in terms of features.

Hence, we are going to talk about some major changes in Selenium 4.0 as well as the revamping that comes along with the changes.

So, let’s get started!

Exciting Selenium 4.0 Features:

It’s good to see that Beta testing is taken seriously this time. And this latest version of Selenium is going to open up better avenues for test automation.

Here’s what Selenium 4 features be providing to its users:

1- Grid Enhancement

The new grid for Selenium 4 has become more scalable. This means that the latest version of Selenium will now be able to support Docker and the grid can easily be deployed on Kubernetes. Moving away from setting up heavy virtual systems to containers. You’ll be able to better manage the Selenium grid as nodes and hubs won’t require separate boot up or testing.

2- IDE Upgradation

Selenium IDE was a playback and record tool built as an add-on for firefox but it got removed due to its latest version. However, with Selenium 4, IDE has been upgraded to support a wider pool of web browsers including Chrome and Firefox.

The new Selenium 4 IDE has the following features:

  • The control flow mechanism has been improved. Testers can now write better ‘While’ and ‘If’ conditions.
  • Code test recording done through Selenium 4 IDE can be exported to a wider pool of languages that include: Java, .NET, JavaScript or Python.
  • Improved GUI

3- Relative Locators

The latest version of Selenium is now equipped with relative locators that can help track down web elements near a specified element.

This relative locator is supported (in selenium 4 java) and (in selenium 4 python).

4- Better Documentation

One of the pleasing aspects about the latest version of Selenium is that it will have proper documentation for support. The earlier versions of Selenium had inadequate documentation making it difficult for users to leverage all the features it had. But with Selenium 4, a clean UI has been developed so that users can easily navigate to their desired section and get the support they need to operate the specific tools.

Testers won’t have to waste their time in gaining information about the necessary features to get started.

5- Chrome Debugging Protocol Support

Selenium 4 has native support to chrome development tool that allows to use the following development properties such as:

  • Fetch
  • Network
  • Profile
  • Performance
  • Application Cache
  1. The CPD support allows testers to resolve bugs even faster for specific web pages.
  2. Poor network connection and Geo location testing can be performed through the API offered by chrome dev tools.
  3. This feature lets testers check out the product in multiple networks such as 3G. 4G and 5G

6- Improved Tab Management

On the previous version of Selenium, testers had to create a new web driver object to manage multiple tabs or windows. But the latest version of Selenium is equipped with a new API – newWindow that lets testers open and switch between multiple windows so now there won’t be a need for creating a web driver object every time for multiple tab operation.

7- Integration of Telemetry + GraphQL

Telemetry is a framework that will now be supported with Selenium grid in this new upgrade. This will give testers a deeper insight into the grid and allow them to know if something goes wrong in due time.

Moreover, the GraphQL powers the new front-end console in the grid. The GraphQL will run with the Selenium grid which will enable testers to pull out useful metrics from the grid to fulfill the requirements accordingly.
