in this article it says flight tests at Hamburg for an A380 requires 11 people, and flight tests for an A320 requires 4 people.
As a production test pilot based in Hamburg, my working day begins around 7am with a "rejected take-off", which is like driving at 115mph in your car to make sure the brakes work. After that we may fly up to twice a day. If we’re conducting a first flight profile, which is the very first time a new aeroplane will take off, every system needs to be tested very thoroughly; from flight controls through to hydraulics, fuel and electrics. The crew can consist of up to 11 people if we’re testing the Airbus A380, the world’s largest passenger airliner, but more commonly when we’re testing the A320, there’ll be four of us; two of whom are pilots.

That's only the flight crew ... Many more people are needed to monitor the datalinks, analyse the data, support the aircraft ...
It takes the teams in the flightline at least 3 to 4 hours to do all the pre-flight checks, then the really, really important bits are done by the 'Qualitäts-Sicherung' (always called 'QS'-->quality assurance) and I think that the test pilots don't even check the plane through from outside before the flight (can't remember that they did for the two test flights i was in the flightline for MSN 132 and we did the 'pre flight')
