Test-Driven iOS Development with Swift - Fourth Edition: Write maintainable, flexible, and extensible code using the power of TDD with Swift 5.5 (Paperback)

Build robust applications using TDD with Swift 5.5 and become a TDD expert by writing tests for view controller, views, network code, and even SwiftUI view

Key Features

• Build a complete iOS app using test-driven development
• Explore testing view controllers, table views, navigation, and network code
• Learn how to write tests for Combine and SwiftUI code

Book Description

Test-driven development (TDD) is a proven way to find software bugs earlier on in software development. Writing tests before you code improves the structure and maintainability of your apps, and so using TDD in combination with Swift 5.5's improved syntax leaves you with no excuse for writing bad code.

Developers working with iOS will be able to put their knowledge to work with this practical guide to TDD in iOS. This book will help you grasp the fundamentals and show you how to run TDD with Xcode. You'll learn how to test network code, navigate between different parts of the app, run asynchronous tests, and much more. Using practical, real-world examples, you'll begin with an overview of the TDD workflow and get to grips with unit testing concepts and code cycles. You'll then develop an entire iOS app using TDD while exploring different strategies for writing tests for models, view controllers, and networking code. Additionally, you'll explore how to test the user interface and business logic of iOS apps and even write tests for the network layer of the sample app.

By the end of this TDD book, you'll be able to implement TDD methodologies comfortably in your day-to-day development for building scalable and robust applications.

What you will learn

• Implement TDD in Swift application development
• Detect bugs before you run 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's a joy to read and maintain
• Design functional tests to suit your software requirements
• Discover scenarios where TDD should be applied and avoided

Who this book is for

This book is for iOS developers looking to apply TDD to build maintainable and scalable applications. Intermediate-level developers with Swift application development experience will be able to make the most out of this book. Prior experience of applying TDD to Swift applications is not required.

使用 TDD 和 Swift 5.5 建立強大的應用程式，並透過為視圖控制器、視圖、網路程式碼甚至 SwiftUI 視圖撰寫測試，成為 TDD 專家。

主要特點：

- 使用測試驅動開發建立完整的 iOS 應用程式
- 探索測試視圖控制器、表格視圖、導航和網路程式碼
- 學習如何為 Combine 和 SwiftUI 程式碼撰寫測試

書籍描述：

測試驅動開發（TDD）是一種在軟體開發早期發現軟體錯誤的有效方法。在編寫程式碼之前撰寫測試可以改善應用程式的結構和可維護性，因此使用 TDD 結合 Swift 5.5 的改進語法，您將無法找到編寫糟糕程式碼的藉口。

在這本實用指南中，iOS 開發人員將能夠將他們的知識應用於 TDD。本書將幫助您掌握基本原理，並向您展示如何在 Xcode 中運行 TDD。您將學習如何測試網路程式碼、在應用程式的不同部分之間導航、運行非同步測試等等。通過實際的實例，您將從 TDD 工作流程的概述開始，並熟悉單元測試的概念和程式碼循環。然後，您將使用 TDD 開發整個 iOS 應用程式，同時探索為模型、視圖控制器和網路程式碼撰寫測試的不同策略。此外，您還將探索如何測試 iOS 應用程式的使用者介面和業務邏輯，甚至為範例應用程式的網路層撰寫測試。

通過閱讀本書，您將能夠在日常開發中舒適地實施 TDD 方法，以建立可擴展和堅固的應用程式。

您將學到什麼：

- 在 Swift 應用程式開發中實施 TDD
- 使用 TDD 方法在執行程式碼之前檢測錯誤
- 使用 TDD 建立模型、視圖控制器和視圖
- 使用非同步測試和存根測試網路程式碼
- 編寫易於閱讀和維護的程式碼
- 根據軟體需求設計功能測試
- 發現應用 TDD 的場景和避免的情況

本書適合對象：

本書適用於希望應用 TDD 建立可維護和可擴展應用程式的 iOS 開發人員。具有 Swift 應用程式開發經驗的中級開發人員將能夠充分利用本書。不需要先前將 TDD 應用於 Swift 應用程式的經驗。
