Adaptive Code: Agile coding with design patterns and SOLID principles

Write code that can adapt to changes.

By applying this book's principles, you can create code that accommodates new requirements and unforeseen scenarios without significant rewrites. Gary McLean Hall describes Agile best practices, principles, and patterns for designing and writing code that can evolve more quickly and easily, with fewer errors, because it doesn't impede change.

Now revised, updated, and expanded, Adaptive Code, Second Edition adds indispensable practical insights on Kanban, dependency inversion, and creating reusable abstractions. Drawing on over a decade of Agile consulting and development experience, McLean Hall has updated his best-seller with deeper coverage of unit testing, refactoring, pure dependency injection, and more.

Master powerful new ways to:

Write code that enables and complements Scrum, Kanban, or any other Agile framework

Develop code that can survive major changes in requirements

Plan for adaptability by using dependencies, layering, interfaces, and design patterns

Perform unit testing and refactoring in tandem, gaining more value from both

Use the "golden master" technique to make legacy code adaptive

Build SOLID code with single-responsibility, open/closed, and Liskov substitution principles

Create smaller interfaces to support more-diverse client and architectural needs

Leverage dependency injection best practices to improve code adaptability

Apply dependency inversion with the Stairway pattern, and avoid related anti-patterns
