Not quite sure what you are getting at.
The "lesson" type is a "checkout" (In addition to proving your flying skills you will also be tought the local procedures) which is conducted by a person examining your prowess (the "examiner") and it is a "test" because you have to meet a standard otherwise you will not have completed the exercise.
Excellent point about adopting the attitude of "flying as the Captain with a friendly passsenger"
