## Abstract

A method is provided. The method includes determining, in a determination by an electronic testing device, one or more locations in a cellular network where a test case is to be executed, a time at which the test case is to be executed at the one or more locations, a number of times the test case is to be executed at the one or more locations, or a type of a test equipment on which the test case is to be executed. A test context for testing a user equipment is determined based on a result of the determination. An optimal test case is determined from a test case repository, based on the test context, and the optimal test case is executed.

## Claims
