I'm a bit confused by this approach. Is it related to some established design approach or principles?
What is MVP or BDD? Could you provide an example of your process?
Would it be similar to this example? 1. I want to put out a rpg for iOS. 2. Implement a pokemon style battle system -> when health < 0, NPC dies. 3. Not sure where automation fits in? 4. Code it and test until it works. 5. Move on to adding experience when killing an enemy, etc.
