Not sure what they are called these days, but every military aircraft type used to have a Flight Test Schedule - it was an AP -5M. Every flight test requirement was listed, depending on the reason for the flight test. Nothing particularly secretive about flight tests, just a lot of accurate, timed, methodical data taking with the occasional Vne dive to wake the crew up and to check all the important bits stayed attached.
PS. You can buy old Flight test Schedules (5M) off Amazon etc. if you are that curious. Just seen one for the Hunter on sale.
