NS Instance Usage START Notification
    [Documentation]    Test ID: 9.3.2.3.1
    ...    Test title: NS Instance Usage START Notification
    ...    Test objective: The objective is to test the dispatch of NS Instance Usage Start Notification when the usage of an NS instance is started, 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 subscription for NS instance usage notification is available in the NFVO.
    ...    Reference: Clause 8.5.5.3.1 - ETSI GS NFV-SOL 011 [6] v3.3.1
    ...    Config ID: Config_prod_NFVO
    ...    Applicability: none

    [Documentation]    Test ID: 9.3.2.3.2
    ...    Test title: NS Instance Usage END Notification
    ...    Test objective: The objective is to test the dispatch of NS Instance Usage End Notification when the usage of an NS instance is ended, 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.
