FAQPage Schema
How do I refactor code safely without changing behavior?

Refactoring code safely requires existing tests and a plan for small, verifiable changes. You improve structure incrementally across functions, classes, and modules without altering behavior.

What is the best way to improve code structure across multiple modules?

Improving code structure across modules involves incremental refactoring techniques like Extract Method, Extract Class, and Replace Conditional with Polymorphism. These methods ensure safe, verifiable changes that preserve behavior.

Do I need existing tests to refactor my codebase?

Yes, existing tests are required. Refactoring demands a plan for small, verifiable changes to preserve backward compatibility, and tests confirm that your structural improvements do not alter behavior.

When should I use incremental refactoring instead of rewriting code?

Use incremental refactoring when you need safer upgrades and easier maintenance without breaking existing behavior. It allows you to apply small, verifiable structural changes across functions and classes.

Can I use extraction methods to clean up legacy code?

Yes, extraction methods like Extract Method and Extract Class help clean up legacy code. These techniques improve design and maintainability incrementally while tests verify behavior preservation.
