Test-driven development (TDD) is a proven way to find software bugs early. Writing tests before your code improves the structure and maintainability of your apps. In combination with the improved syntax of Swift 3, there is no excuse or writing bad code.
This book will help you understand the process of TDD and how it impacts your apps written in Swift. Through a practical, real-world example app, you’ll start seeing how to implement TDD in context. You will begin with an overview of the TDD workflow and then deep dive 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 the view controllers and the helper classes. Next, you’ll learn how to write tests for network code, what CI is and how to set it up using Xcode Server.
Finally, the book will guide you through the next steps to become a testing expert by discussing integration tests, Behavior Driven Development (BDD), open source testing frameworks and UI Tests introduced in Xcode 8.
Dr. Dominik Hauser completed his Ph.D. from the University of Heidelberg in Physics. While working as a university professor, he started iOS development in his spare time. His first app on Physics has been an astounding success worldwide. Since then, he turned himself into a full-time iOS developer, crediting number of successful apps to his name. He has been a Swift developer since day one and runs a blog on iOS development, www.swiftandpainless.com.
