Safe code refactoring requires an analysis-first methodology with incremental changes, verifying that all tests pass before and after each transformation to guarantee functional equivalence and behavior preservation throughout the process.

Common code smells include God Classes, Feature Envy, and Long Parameter Lists. Identifying these structural issues during the analysis phase guides targeted remediation through techniques like Extract Method and Move Method.

Breaking down complex functions uses the Extract Method technique to split logic into smaller, manageable methods. This incremental refactoring approach ensures tests continue passing throughout the transformation process.

Yes, large classes with too many responsibilities, known as God Classes, can be refactored incrementally. The process uses disciplined transformations like Move Method to split responsibilities while maintaining functional equivalence.

Fixing Long Parameter Lists involves applying targeted refactoring techniques to consolidate or group parameters. This disciplined approach improves code quality and maintainability while ensuring tests pass before and after changes.
