<[체험판] Test-Driven iOS Development with Swift 4 Third Edition> ▶Book Description
Test-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).
▶What You Will Learn
- Implement TDD in Swift application development
- Find bugs before you enter code using the TDD approach
- Use TDD to build models, view controllers, and views
- Test network code with asynchronous tests and stubs
- Write code that is a joy to read and maintain
- Develop functional tests to ensure the app works as planned
▶Key Features
- A practical guide to writing effective, organized, and clean code that works well
- Learn test-driven principles to help you build better-designed apps with fewer bugs
- A comprehensive overview of the techniques available for TDD in Swift
▶Who This Book Is For
▶What this book covers
- Chapter 1, Your First Unit Tests, walks you through your first unit tests using Xcode and discusses the benefits of using TDD.
- Chapter 2, Planning and Structuring Your Test-Driven iOS App, introduces the app you are going to write through the course of this book and how to set up a project in Xcode.
- Chapter 3, A Test-Driven Data Model, discusses the TDD of a data model.
- Chapter 4, A Test-Driven View Controller, shows you how to write tests for a view controller, and describes how to use fake objects to isolate micro features for the test.
- Chapter 5, Testing Network Code, teaches you to test network code using stubs to fake a server component before it is developed.
- Chapter 6, Putting It All Together, walks you through the integration of all the different parts developed in previous chapters and shows the use of functional tests.
- Chapter 7, Code Coverage, shows you how to measure the code coverage of your tests using Xcode.
- Chapter 8, Where to Go from Here, wraps up and shows you the possible next steps to improve your acquired testing skills.
▶Editorial Review
iOS projects have become bigger and more complex. Many projects have already surpassed desktop applications in their complexity. One important strategy to manage this complexity is through the use of unit tests. By writing tests, a developer can point out the intention of the code and provide a safety net against the introduction of bugs.
By writing tests first (test-driven development), the developer focuses on the problem. This way, they are forced to think about the domain and rephrase a feature request using their own understanding by writing the test. In addition to this, applications are written using TDD only containing code that is necessary to solve the problem.
As a result, the code is clearer, and the developer gains more confidence that the code actually works.
In this book, you will develop an entire iOS app using TDD. You will experience different strategies for writing tests for models, view controller, and networking code.

Dr. Dominik Hauser completed his PhD in physics from the University of Heidelberg. 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 has turned himself into a full-time iOS developer, with a number of successful apps to his name. He has been a Swift developer since day one and runs a blog on iOS development.
