Enabling a zero touch experience Template driven mobile test scenarios
18 February 2016 5
HTML5 UI framework – Deliver Unique views per test
case configuration
Template driven – Minimal user configuration
requirements, pre-populated parameters
Profile enabled – Create subscriber profiles for
application traffic scenarios
– Create mobility scenarios e.g. UE groups moving between cell towers
