*** Test Cases ***
ONU MIB Template Data Test
    [Documentation]    Validates ONU Go adapter storage of MIB Template Data in etcd and checks the usage
    ...                - setup one ONU
    ...                - request MIB-Upload-Data by ONU via OMCI
    ...                - storage MIB-Upload-Data in etcd
    ...                - store setup duration of ONU
    ...                - check Template-Data in etcd stored (service/%{NAME}/omci_mibs/go_templates/)
    ...                - setup second ONU
    ...                - collect setup durationof second ONU
    ...                - compare both duration
    ...                - duration of second ONU should be at least 10 times faster than the first one
    ...                - MIB-Upload-Data should not requested via OMCI by second ONU
    ...                - MIB-Upload-Data should read from etcd
