    [Documentation]    Test ID: 5.x.y.x
    ...    Test title: Scale out VNF operation
    ...    Test objective: The objective is to test a scale out of an existing VNF instance
    ...    Pre-conditions: VNF instance in INSTANTIATED state (Test ID: 5.a.b.c)
    ...    Reference: section 5.4.5 - SOL003 v2.4.1
    ...    Config ID: Config_prod_VNFM
    ...    Applicability: Scale operation is supported for the VNF (as capability in the VNFD)
    ...    NFVO is not subscribed for
    ...    Post-Conditions: VNF instance still in INSTANTIATED state and VNF was scaled
    Send VNF Scale Out Request
    Check HTTP Response Status Code Is    202
    Check HTTP Response Header Contains    Location 
    Check Operation Occurrence Id
    Check Operation Notification For Scale   STARTING
