zhfeng commented on issue #173: [SCB-300] acceptance test for @Compensable event timeout
   what is the purpose of this test ? I think it would like to show the scenario that when
the saga transaction is timeout, the alpha server call the compensate method is failed and
will retry ?
   The booking service looks like the following steps:
   1) saga start
   2) call the car booking
   3) call the hotel booking
   4) postBooking wait 10s until the transaction timeout (injected by the byteman rules)
   5) return failure message with the information of timeout ( I think it is still an issue
when we are sending the SAGA_ENDED in the
I think we should check the return value and throws the Exception if the transaction is timeout.
Also the alpha server handles the message in (,
currently it only check if the transaction is aborted and I think it should also check if
the transaction is timeout.
   For this test, if we want to simulate the alpha server retries the compensate method when
the transaction is timeout, I think it would like to use the byteman rule in the cancel method
of HotelBooking (
   RULE create counter
   CLASS org.apache.servicecomb.saga.demo.pack.hotel.HotelBooking
   METHOD <init>
   DO createCountDown($0, 1)
   RULE throws the exception when calling the cancel method at the first time
   CLASS org.apache.servicecomb.saga.demo.pack.hotel.HotelBookingService
   MEHTOD cancel(HotelBooking)
   IF !countDown($0)
   DO throw exception
