The Surprising Effectiveness of Small Steps
summary
Presents the practice of making named, tiny code transformations to reduce bugs and enable safe large refactors on legacy code. Shows a TCR (Test && Commit || Revert) tool called murexTCR that runs tests automatically, demonstrates FizzBuzz implemented in four incremental baby steps plus four cleanup steps, and enumerates concrete transforms like extract method, extract constant, add test, add case, and replace expression. Describes a real-world migration of a broker connector done incrementally, deployed without issues for two days and with easier debugging thanks to clearer logs.
