Your TDD Treasure Map
summary
Shows how to turn ticket acceptance criteria into a concrete flowchart-to-tests workflow for a Rails controller: drawn happy path, add validation branch, add auth branch, then write RSpec request examples for redirect, DB update, and render-on-error. Demonstrates isolating complex auth into an authorization service object, quantifies path blowup (four to seven contexts), and mentions tooling and notation like askiflo.com for ASCII flowcharts and Capybara-style examples.
