Does GenAI Mean the Death of Test-Driven Development (TDD)
summary
Shows TDD staying useful while GenAI speeds the boring parts: uses Rider and AI Assistant plus the Juny agent to generate unit tests and minimal domain code for concrete rules (create matching shift, propagate volunteer count, prevent overassignment, require valid license, 12‑hour/month cap). Prompts and a markdown rules file steer generation; AI patches code, adds domain exception handling, and runs tests — all tests end green in the demo — though Juny ↔ AI Assistant integration is not yet fully unified.
