To me, fitness testing to dictate whether someone is fit to play is about two principles: Is an injury evident on examination and can they do the tasks that the sport requires them to do without their injury coming back or limiting them.
So for football, this would certainly involve tesing positive special tests, flexibility and any other aggrivating factors that came to light during the initial injury assessment or whatever.
If that was all ok then a good general warm up followed by sprinting, changing direction, jumping and kicking a football in every way. The aim of a fitness test is to decide whether an injury will hold up to the stress of a game and for that you have to throw in the physical components of the sport you're testing for.
