Refactoring

Quick Start

1. Define scope and boundaries
2. Cover with tests
3. Refactor in small steps (one technique per commit)
4. Verify after each change

Workflow

Before Refactoring

• Define scope, find boundaries (junction points between code to change and everything else)
• Cover with tests (edge cases, explicit/implicit input, specify desired result on boundaries)
• Make linter/compiler stricter
