Module 11 Summary

What this module established

Take the model as a parameter and everything except the model's own behaviour becomes testable with no key, no cost and no network - which is where most bugs actually live.

Carry forward

• Script the fake's responses to drive retry, refusal and give-up paths. You cannot make a real model return invalid JSON on demand.
• Assert on citations, figures, length and absence of hedging. Exact-match assertions fail on harmless rewording and end up disabled.
• Split the offline suite from the paid one and keep it fast. A suite that takes minutes is a suite people stop running.

Before moving on

Move on when the offline suite passes with no key in seconds, and the refusal and retry paths are both exercised.
