How to Practice Test Driven Development without Shooting Yourself in the Foot
summary
Practical advice for keeping Test‑Driven Development fast and reliable when tests interact with real infrastructure: replace heavy database calls with an in‑memory datastore, isolate boundaries using explicit interface contracts and a small domain‑specific contract DSL, and test projections/JSON responses end‑to‑end only at the boundary. Recommends focused unit tests with thin integration checks, and includes code snippets, a mockable projector library, and examples that reduce overall test runtime.
