Documentation Test different Reconcile scenarios of ONU Go adapter with all three workflows ATT, DT and TT.
... Test suite is dedicated for only one ONU! Run robot with bbsim-kind.yaml only!
... Not for DT/TT workflow!
... Hint: default timeout in BBSim to mimic OLT reboot is 60 seconds!
... This behaviour of BBSim can be modified by 'oltRebootDelay: 60' in BBSim section of helm chart or
... used values.yaml during 'voltha up'.
