Keynote: Refactoring Superpowers: Make Your IDE Do Your Work, Faster and More Safely
summary
Refactors a 1,004 line C# sudoku solver into small, safe commits using JetBrains and Visual Studio refactorings and ApprovalTests to capture console output and stabilize RNG seeding so tests become deterministic. Uses extract method and introduce parameter repeatedly, adds a Grid.solve static API, raises a 90% covered play method to 100% by looping tests, and saves each successful microrefactor to git so changes are reversible and the solver still correctly solves external puzzles.
