// 03 Challenge
As every testing task, the challenge is to find the proper approach and structure starting from smoke and small scale tests to identify the proper component versions (integration) to run the large scale and regression tests with. Log analysis is an important part to assign the issue to proper development team and providing the set of relevant information.
Regression Tests of the ETSI deliveries are part of the tasks at the customer’s T&M telecommunication platform. This platform is a (e)NodeB emulation and the ATS testcases are verified again the various mobile phone vendors in LTE, UMTS and GSM networks.
