"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."
