Test-Driven iOS Development with Swift 4 – Third EditionUse test-driven approach to develop highly-functional iOS apps with Swift 4 and Xcode 9About This BookA practical guide to writing effective, organized, and clean code that works wellLearn test-driven principles to help you build better-designed apps with fewer bugsA comprehensive overview of the techniques available for TDD in SwiftWho This Book Is ForTo get the most out of this book, you will need some prior experience with Swift application development. You may have already heard about Test-Driven Development (TDD) but you don’t need any prior experience of applying it to Swift applications.What You Will LearnImplement TDD in Swift application developmentFind bugs before you enter code using the TDD approachUse TDD to build models, view controllers, and viewsTest network code with asynchronous tests and stubsWrite code that is a joy to read and maintainDevelop functional tests to ensure the app works as plannedIn DetailTest-driven development (TDD) is a proven way to find software bugs early. Writing tests before you code improves the structure and maintainability of your apps. Using TDD, in combination with Swift 4’s improved syntax, means there is no longer any excuse for writing bad code.This book will help you understand the process of TDD and how to apply it to your apps written in Swift.Through practical, real-world examples, you’ll learn how to implement TDD in context. You will begin with an overview of the TDD workflow and then delve into unit-testing concepts and code cycles.You will also plan and structure your test-driven iOS app, and write tests to drive the development of view controllers and helper classes. Next, you’ll learn how to write tests for network code and explore how the test-driven approach’in combination with stubs’helps you write network code even before the backend component is finished.Finally, the book will guide you through the next steps to becoming a testing expert by discussing integration tests, Behavior Driven Development (BDD), open source testing frameworks, and UI Tests (introduced in Xcode 9).Style and approachUsing a step-by-step approach, you will develop an entire iOS app using TDD. During the course of the book, you will explore different strategies for writing tests for models, View Controllers, and networking code. ISBN: 9781788475709, 1788475704
