The Refactoring Pyramid
summary
The talk presents the “refactoring pyramid,” a counterpart to the test pyramid that links test coverage levels to safe refactoring scope. It explains how to use test-covered layers (modules, packages, classes) as a mirror to guide refactorings from low-level changes (smaller methods, classes, extracted interfaces) up to higher-level abstractions (introducing design patterns). The concept is demonstrated by refactoring code from a single class into the Interpreter pattern.
