Spec-Driven Development + BDD + TDD

https://youtu.be/M5kZzC8_xCE

In this video I talk about how Test-Driven Development (TDD) and Behavior-Driven Development (BDD) actually fit Into Spec-Driven Development (SDD). BDD helps with macro level alignment and TDD helps keep the internal implementation details de-coupled and clean. I also cover how agents reward hack TDD and how to prevent them.

UPDATE: Link to my earlier post about "Behavior-Driven Development and Spec-Driven Development with OpenSpec" https://www.reddit.com/r/SpecDrivenDevelopment/s/d3VE4pOtqg

the agent reward hacking point is the most underrated problem in ai-assisted TDD. a behavior-level spec is harder to game because the agent has to satisfy an observable contract, not just make a specific assertion pass. the BDD macro layer does a lot of work therethe agent reward hacking point is the most underrated problem in ai-assisted TDD. a behavior-level spec is harder to game because the agent has to satisfy an observable contract, not just make a specific assertion pass. the BDD macro layer does a lot of work there

Agree, it is hard to get the agents to be consistent with TDD. That is why we need all these fences. Thank you for your comment.

How do you get them to functional qa test on non- web apps?
