Gilding the Rose: Refactoring-Driven Development
summary
Walks the Gilded Rose kata from a tangled C# updateQuality method (16 ifs, 3 elses, quality assigned up to four times, indentation level 6) to a tested, incremental refactor: replace counting loops with foreach/range, shrink conditionals, extract a quality adjustment value computed once, clamp with min/max, add conjured items via tests, then replace hard‑coded string checks with regexes and a rule table (find first matching rule using LINQ) to yield a compact, declarative rule engine that preserves behavior while making future changes trivial.
