FAQPage Schema
How do I safely refactor existing code without introducing regressions?

Safe refactoring requires enforcing test-first changes and traceability to prevent regressions. You define scope boundaries, update or add tests, and validate changes using regression checks to ensure no new features are added during the process.

What is the minimum test coverage needed to start a code refactoring process?

A code refactoring process requires a minimum of 80% test coverage. Reaching this threshold before making changes ensures existing behavior is validated, allowing scoped module updates to proceed safely without introducing regressions.

How do I define safe boundaries for refactoring across modules or services?

Defining safe boundaries for refactoring across modules or services requires scope analysis. This process identifies targeted ranges, ensuring structural changes remain isolated and traceable while preventing unintended side effects.

Can I add new features while performing a test-driven code refactor?

You cannot add new features while performing a test-driven code refactor. The process strictly enforces scope boundaries to isolate structural improvements, requiring a formal rewrite plan if new functionality is necessary.

When do I need a formal plan for rewriting code instead of a standard refactor?

A formal plan for rewriting code is necessary when standard scoped refactoring cannot achieve the desired maintainability goals. This approach outlines structural rewrites while maintaining test-first validation and regression checks.

How do I integrate documentation traceability into a refactoring workflow?

Documentation traceability integrates into a refactoring workflow through the DevDocs system. This tracks scope analysis, test updates, and structural changes, ensuring code-quality collaboration throughout the module improvement process.
