1. At least one non-transitory computer-readable storage medium storing instructions to generate a test case associated with a test radio access network (RAN) of a wireless telecommunication network based on key performance indicators (KPIs) associated with a production RAN of the wireless telecommunication network, which, when executed by at least one data processor of a system, cause the system to:
obtain the KPIs associated with the production RAN of the wireless telecommunication network;
transform the KPIs into relevant variables including a type of traffic associated with the production RAN, traffic characteristics associated with the production RAN, types of multiple mobile devices interacting with the production RAN, user traffic characteristics, and a number of each type of the multiple mobile devices interacting with the production RAN;
obtain capabilities of multiple mobile devices interacting with the test RAN;
create the test case based on the relevant variables and the capabilities of the multiple mobile devices interacting with the test RAN by:
adjusting a type of traffic associated with the test RAN,
wherein the type of traffic includes data, voice, short message service (SMS), and a direction including upload and download;
adjusting traffic characteristics including call duration and traffic load; and
adjusting the capabilities of the multiple mobile devices interacting with the test RAN to match the types of the multiple mobile devices interacting with the production RAN and the number of each type of the multiple mobile devices interacting with the production RAN;
run a simulation of the test case interacting with the test RAN to obtain simulation KPIs;
determine whether the simulation KPIs correspond to the KPIs associated with the production RAN;
upon determining that the simulation KPIs correspond to the KPIs associated with the production RAN, store the test case in a database; and
upon determining that the simulation KPIs do not correspond to the KPIs associated with the production RAN, adjust the test case.
