# **CUG Testing Steps** 



* The Closed User Group (CUG) functions as a testing process to validate new features and UI adjustments before deploying them into the live production environment.
* This step ensures that modifications do not disrupt the smooth flow of live transactions.
* Upon successful validation of UI changes and feature functionality within the CUG environment, please provide your approval so that we can initiate the release process.
* Once the release is completed, the updated features and UI modifications will be rolled out to all live users, ensuring a seamless transition.

> **Warning**
> **CUG changes take time to reflect on Android/iOS devices hence it is recommended to terminate the app a couple of times to get the changes.**
