Test-Driven iOS Development
Пра гэту электронную кнігу
Long-time iOS/Mac developer Graham Lee helps you rapidly integrate TDD into your existing processes using Apple’s Xcode 4 and the OCUnit unit testing framework. He guides you through constructing an entire Objective-C iOS app in a test-driven manner, from initial specification to functional product. Lee also introduces powerful patterns for applying TDD in iOS development, and previews powerful automated testing capabilities that will soon arrive on the iOS platform. Coverage includes
- Understanding the purpose, benefits, and costs of unit testing in iOS environments
- Mastering the principles of TDD, and applying them in areas from app design to refactoring
- Writing usable, readable, and repeatable iOS unit tests
- Using OCUnit to set up your Xcode project for TDD
- Using domain analysis to identify the classes and interactions your app needs, and designing it accordingly
- Considering third-party tools for iOS unit testing
- Building networking code in a test-driven manner
- Automating testing of view controller code that interacts with users
- Designing to interfaces, not implementations
- Testing concurrent code that typically runs in the background
- Applying TDD to existing apps
- Preparing for Behavior Driven Development (BDD)
The only iOS-specific guide to TDD and unit testing, Test-Driven iOS Development covers both essential
concepts and practical implementation.

Graham Lee's job title is “Smartphone Security Boffin,” a role that requires a good deal of confidence in the code he produces. His first exposure to OCUnit and unit testing came around six years ago, as test lead on a GNUstep-based server application. Before iOS became the main focus of his work, Graham worked on applications for Mac OS X, NeXTSTEP, and any number of UNIX variants.
This book is the second Graham has written as part of his scheme to learn loads about computing by trying to find ways to explain it to other people. Other parts of this dastardly plan include speaking frequently at conferences across the world, attending developer meetings near to his home town of Oxford, and volunteering at the Swindon Museum of Computing.
