The earlier version of
Selenium Grid was complex to set up and rigid in terms of scaling.
The new Selenium Grid comes with Docker support. This will enable developers or testers to spin up the containers rather than setting up heavy virtual machines. Moreover, it is redesigned in a way that will allow QAs to deploy the grid on Kubernetes for better scaling.
Managing Selenium Grid is now smooth and easy as there will no longer be any need to set up and start hubs and nodes separately.
Teams or individual testers can now deploy the grid in three modes:
* Standalone mode
* Hub and Node
* Fully distributed
Unlike in earlier versions, the Grid will now support IPv6 addresses and one can communicate with the Grid using the HTTPS protocol. In Grid 4, the configuration files used for spinning up the grid instances can be written in TOML (
Tom’s Obvious, Minimal Language) which will make it easier for humans to understand.
The Grid in Selenium 4 also comes with an enhanced user-friendly GUI. Overall, the revamped Selenium Grid will enhance the DevOps process as it provides compatibility with tools like Azure, AWS, and more.
