refactor-code

To safely refactor code with tests, apply a test-first workflow that locks in existing behavior before making incremental changes. This structured approach validates post-change code against benchmarks to ensure maintainability without introducing bugs.

Refactoring long functions and duplicated code is best handled through small, verifiable, incremental edits guided by a test-driven approach. This reduces risk by validating each change against a behavioral benchmark before moving forward.

Yes, you can use a test-driven refactoring workflow on both large and small codebases. The process handles complex conditionals and long functions by enforcing incremental changes and post-change validation across software projects of any scale.

Test-first refactoring handles complex conditionals by writing tests that lock in the current behavior before simplifying the logic. This ensures that incremental structural changes improve readability without altering the original execution outcomes.

You should not use incremental refactoring when lacking test coverage to validate behavior, as this test-first approach relies on benchmarking examples to verify post-change logic and prevent regressions in complex codebases.
