A deep dive into the Gilded Rose
summary
Walks through taking the Gilded Rose kata from untrusted legacy code to a working change: adds conjured items that degrade quality twice as fast by detecting names via an 8‑char prefix, fixes the odd‑number decrement bug, and updates the golden master. Uses Approval Tests with Catch2, precompiled headers to cut debug compile from 2.2s to 1.4s, verifies 100% line coverage with Bullseye, munges timestamps in logs, exercises generators in Catch2 for property‑style tests and uses Trompeloeil mocks and simple stubs to test logging without file IO.
