Live Mob Refactoring
summary
Live mob refactoring builds a working Poker Dice hand scorer by iterating on Ruby code and RSpec tests, starting with 32 tests 29 pending and driving behavior with tiny failing specs. The group uses count-based hand classification, lightweight refactors, occasional “janky” hacks to unblock tests, and simplifies a brittle custom matcher; straights, full house, four/five of a kind all get implemented and the test suite ends green, demonstrating mobbed TDD in practice.
