If interested for a beginner's opinion, this is what i did for a non-player ship i created.
1. First off all, force your model to move, accelarate, stop and wrapin/out.
2. Put it to a fight whith several combinations off fighters/bombers (do not interfere to the batle)
3. Same as above, only this time make the attackers destroy subsystems. It's good to originally place the attackers in angles where the subsystems are not visible.
4. If there is a fighterbay, check the docking/undocking procedure.
5. Same as above for docking spots. It's critical to use several sised docker ships.
6. Put your model to dock/undock to other ships/stations even though the bugs in this case are usually their problem.
7. Force it to collide whith bigger/smaller thinks.
8. Put it to fight whith anything close to it's class.
9. Fly far from it, close to it and try to (sounds weird, i know) penetrate it.
10. Make combinations off all the above. This is extremely boring but try to do as much as you can.
