Working Effectively with Legacy Code (Robert C. Martin Series)

This book offers practical strategies for working with large, untested legacy code bases, helping developers understand their code better, make safer changes, and improve performance, functionality, reliability, and manageability.

With a focus on real-world examples and case studies, the author provides a comprehensive guide to understanding and managing legacy systems, including techniques for identifying where code changes need to be made, coping with non-object-oriented applications, and using dependency-breaking techniques to work with program elements in isolation.

Whether you're a developer, technical manager, or tester, this book will give you the tools you need to get more out of your legacy systems and make meaningful improvements to your organization's software development efforts.
