... Test title: VNF Instance Scale Out workflow
... Test objective: The objective is to test the workflow for the scaling out a VNF instance
... Pre-conditions: VNF instance in INSTANTIATED state (Test ID 5.4.4.1). NFVO is subscribed to VNF LCM Operation Occurrence notifications (Test ID 5.4.20.1)

... Reference: clause 5.4.5 - ETSI GS NFV-SOL 003 [1] v2.6.1
... Applicability: NFVO is able to receive notifications from VNFM. Scale operation is supported for the VNF (as capability in the VNFD)
... Post-Conditions: VNF instance still in INSTANTIATED state and VNF is scaled out
