umm, no
No, their job was to run a test mission profile and collect data. As long as they were on their way, they were dropping off some supplies. You don't test things just to show they work, you test to discover what can go wrong. In this case, it sounds like a crewed mission would have been given instructions along the lines of "switch CRM-114 to aux" and they'd have continued on their way.
Let's cover some items they did on this mission (overly simplified):
* vehicle assembly
* payload loading/checkout
* fueling
* launch
* staging
* tracking the vehicle
* engine shutdown
* communications while in orbit
* maneuvering (successful, but exhausted propellant due to issues previously noted)
* de-orbit maneuvers
* heat shield performance
* parachute performance
* airbag deployment
* data collection on physiological stresses future astronauts will experience.
Let's cover what they didn't do:
* rendezvous with ISS
* dock with ISS
* depart ISS
In the long run, it may be a bad thing that this mission went so well. Space travel has a history of high-profile underestimations of risk, to put it mildly.
