Adaptive Code: Agile coding with design patterns and SOLID principles, 2nd edition

By applying this book’s principles, students 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 more than a decade of Agile consulting and development experience, McLean Hall has updated this edition 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

• Bridges the gap between theory and practice, guiding students through applying key concepts to a pragmatic agile coding project
• New coverage includes: Kanban for BAU, Domain-Driven Design, Hexagonal Architecture, Test-Driven Development, and Test-First methodology
• Contains expanded coverage of unit testing, refactoring, and Pure Dependency Injection
• Packed with up-to-date C# examples (and written for developers using multiple languages)

This Second Edition expands from 12 to 14 chapters, and all chapters are revised and updated. New coverage includes Kanban for BAU, Domain-Driven Design, Hexagonal Architecture, Test-Driven Development, and Test-First methodology. The Second Edition also includes expanded coverage of unit testing, refactoring, and Pure Dependency Injection.
