*** Test Cases ***
ONU Negative State Test
    [Documentation]    Validates the ONU Go adapter states will never leave starting-openomci
    ...                Due to a 'omci-response-rate' lower than 8 more OMCI messages will be through away by BBSIM than
    ...                repeated by openonu-go-adapter. So ONU will never leave starting-openomci state.
    ...                Timeout has to set at least to 300s (or more)
