- Resource skills and capacity: Testers are required to have an overall grasp of NFV system architectures, familiarity with the tested network elements and interfaces, and corresponding specifications (in the initial stage, 5G core network main network elements such as AMF/SMF/UPF), the testing capabilities of Open Source and commercial tools required for NFV testing, and the development capabilities of automated scripting languages (Restful API, Python, etc.).
