VNF Instance Scale To Level
   [Documentation]    Test ID: 7.3.1.31.1
    ...    Test title: VNF Instance Scale To Level workflow
    ...    Test objective: The objective is to test the workflow for the scale to level of a VNF instance
    ...    Pre-conditions: VNF instance in INSTANTIATED state . NFVO is subscribed to VNF LCM Operation Occurrence notifications 
    ...    Reference: Clause 5.4.6 - ETSI GS NFV-SOL 003 [1] v2.6.1
    ...    Config ID: Config_prod_VNFM
    ...    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 to the new level
    Send VNF Scale To Level Request
    Check HTTP Response Status Code Is    202
    Check HTTP Response Header Contains    Location 
    Check Operation Occurrence Id existence
    Check Operation Notification For Scale   STARTING
    Check Operation Notification For Scale    PROCESSING
    Check Operation Notification For Scale    COMPLETED
    Check Postcondition VNF Scaled To New Level
