I think the whole testing issue is dumb, but that's another topic.
No, Schumacher should not be able to test the F60, purely because Ferrari WOULD take the opportunity to try new components - no doubt about it, anyone would.
Jaime didn't test the STR before racing in Hungary and he made a pretty good fist of things. I'm sure a 7 time WDC and veteran of hundreds of GPs can handle the car after 4 hours free practice in Valencia.
