VNF Indicator Value Change Notification
    [Documentation]    Test ID: 6.3.2.6.1
    ...    Test title: VNF Indicator Value Change Notification
    ...    Test objective: The objective is to test the dispatch of VNF Indicator Value Change Notification when new indicator values are available in the VNF, and perform a JSON schema and content validation of the delivered notification. The action that triggers the notification under test is an explicit test step, but it is not performed by the test system.
    ...    Pre-conditions: A VNF is instantiated, and a subscription for indicator value change notifications is available in the VNF.
    ...    Reference: Clause 8.4.7.3.1 - ETSI GS NFV-SOL 002 [2] v2.4.1
    ...    Config ID: Config_prod_VNF
    ...    Applicability: none
    ...    Post-Conditions: none 
    Trigger the availability of new indicator value in the VNF (external action) 
    Check Indicator Value Change Notification Http POST Request Body Json Schema Is    VnfIndicatorValueChangeNotification
    Check Indicator Value Change Notification Http POST Request Body notificationType attribute Is    VnfIndicatorValueChangeNotification
