*** Test Cases ***
VNF Performance Information Availability Notification
    [Documentation]    Test ID: 7.3.4.8.1
    ...    Test title: VNF Performance Information Availability Notification
    ...    Test objective: The objective is to test the dispatch of VNF Performance Information Availability Notification when new VNF performance information is available in the NFVO, 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 performance job is created, and a subscription for information availability notifications is available in the VNFM.
    ...    Reference: clause 6.4.9.3.1 - ETSI GS NFV-SOL 003 [1] v2.4.1
    ...    Config ID: Config_prod_VNFM
    ...    Applicability: none
    ...    Post-Conditions: none 
    Trigger the availability of VNF Performance Information (external action) 
    Check Performance Information Available Notification Http POST Request Body Json Schema Is    PerformanceInformationAvailableNotification
    Check Performance Information Available Notification Http POST Request Body notificationType attribute Is    PerformanceInformationAvailableNotification

VNF Threshold Crossed Notification
    [Documentation]    Test ID: 7.3.4.8.2
    ...    Test title: VNF Threshold Crossed Notification
    ...    Test objective: The objective is to test the dispatch of VNF Threshold Crossed Notification when a previously set VNF performance metric threshold is crossed, 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 performance job is created, and a threshold subscription is available in the VNFM.
    ...    Reference: clause 6.4.9.3.1 - ETSI GS NFV-SOL 003 [1] v2.4.1
    ...    Config ID: Config_prod_VNFM
    ...    Applicability: none
    ...    Post-Conditions: none 
    Trigger the cross of VNF Performance Threshold (external action) 
    Check Threshold Crossed Notification Http POST Request Body Json Schema Is    ThresholdCrossedNotification
