Help with Function Testing in the Application (CI/cd)

Application: Flutter

BackEnd: Java (Docker and Kubernetes)

Need help with testing(new feature in admin panel) and setting up Ci/Cd process in the future

With professional engineers will be glad to further cooperation.

Description of the task which is now in development;
We need to add to the Beck End in the section: Device_Menegment/Cabinet_List/Edit Equipments


Ability to edit variables on the selected station
(Example in the attached file 'Frame (1)')

*Free Time - Change the number of free time for the user

*Refresh cycle - the time after which the user can use the Free Time again.

Switch On/off (in the Disabled mode, the refresh time to use the Free time is instantaneous).

Rule:
Provided that if the User fails to surrender the device within the set Free Time, the Phase/Tariff Plan is activated. And a pop-up window appears with information (Free time you can use tomorrow) Example in attached file Active Rental (2) .

The free time promotion applies to one device only; if the User tries to take 2 or more devices, the rest of the plan will be included.
Free time and rate information should be displayed to the user when selecting a station. (Example in attached UX design file (link to Figma)
