I don't think there's any doubt that Civil aircraft are tested, prior to initial certification, about as much as Military aircraft prior to RTS - but the tests aren't the same and the civil ones normally get done much faster - and with less fuss.
I believe this is because there may be less parameters to test, but I stand to be corrected. I also believe that, if given the job, Qinetiq would not have completed as many hours as Boeing have on the 787 to date.
UK civil aircraft used to routinely get "handling checks" for C of A renewals and handovers to new owners too, during which there could be some quite upsetting manoeuvers (Thats bound to be spelled wrong).
Does anyone here remember doing C of A Flight Tests and slow speed stalls over the North Sea? All disappeared with the onset of EASA.
