Test-Driven iOS Development

As iOS apps become increasingly complex and business-critical, iOS developers must ensure consistently superior code quality. This means adopting best practices for creating and testing iOS apps. Test-Driven Development (TDD) is one of the most powerful of these best practices. Test-Driven iOS Development is the first book 100% focused on helping you successfully implement TDD and unit testing in an iOS environment.

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.
