- SOLID Design in Action: Build Maintainable Class Hierarchies with Proven Refactoring Patterns for Flexibility, Speed, and TestabilityEvery developer has faced the same nightmare: a codebase so rigid and tangled that one small fix breaks half the system. What should have been a quick feature update becomes days of debugging, and onboarding new teammates feels like dropping them into a maze of technical debt. The frustration isn’t from lack of skill—it’s the inevitable result of systems that outgrow their initial design.SOLID Design in Action offers a practical way out. Instead of abstract theory, this book delivers a hands-on guide to applying the SOLID principles directly to messy, real-world code. Through step-by-step refactoring of a bloated “God class” into a modular, testable architecture, you’ll see exactly how flexibility and maintainability can be built into your software from the inside out. Each chapter tackles a core principle with runnable examples, refactor recipes, and strategies that you can apply immediately to your own projects.By working through the patterns and practices in this book, you will learn how to:Recognize design smells and break down overgrown classes into focused, reusable components.Apply the Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion principles to make code safer to change.Build modular systems with clean APIs, stable boundaries, and automated checks to prevent regressions.Improve testability with unit, integration, and contract tests supported by modern tools like JUnit, PIT mutation testing, and Testcontainers.Extend functionality safely with plugin architectures and drop-in modules—without rewriting proven logic.Balance performance and pragmatism while maintaining design clarity in real-world systems.Whether you’re refactoring a fragile legacy service or mentoring a team toward cleaner practices, this book equips you with the mindset and techniques to transform brittle code into software that welcomes change. You’ll stop fearing refactors and start shipping features with speed and confidence.If you want your code to not only work today but stay flexible tomorrow, SOLID Design in Action is your roadmap. Get your copy now and start building systems that thrive under change.
