I would hesitate to call it a full systems test. Maybe the drive and vacuum systems but that's probably the easy part. The hard part is to make this work while embarking and disembarking pods from a non vacuum atmosphere and handling all failure modes. Just like software development, they're 90% complete but now comes the other 10% which takes 90% of the total time.
