Test-Driven iOS Development with Swift 4 - Third Edition

內容描述

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

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

About the Author
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.
