Test-Driven iOS Development


Book Description

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.




Test IOS Apps with UI Automation


Book Description

If you're an iOS developer or QA professional tapping through an app to reproduce bugs or performance issues you thought were solved two releases ago, then this is your book. Learn how to script the user interface, assert correct behavior, stub external dependencies, reproduce performance problems, organize test code for the long haul, and automate the whole process so the machine does the work. You'll walk through a comprehensive strategy with techniques using Apple's tools that you can apply to your own apps. Automated user interface testing is an important part of a comprehensive testing strategy for iOS applications. By scrutinizing your app through the eyes and actions of the user, you raise confidence that features are wired up right and behave as you expect. Through this book you'll learn how to do full-stack testing of your iOS apps in both the simulator and on the device with Apple's built-in tools. You'll write behavioral tests in UI Automation that help protect against regressions. You'll write scripts to repeat steps in Instruments to reproduce performance bugs. With a little ingenuity, you'll build a workflow that gives the feedback you need. Grow a test suite by working with a real application that uses Core Data and network requests. Learn how to describe expected behavior in test scripts, launch the app in a specific state, and stub external dependencies for completely isolated and repeatable tests. Along the way, you'll practice how to organize your test code and run it hands-free from the command line. By the end, you'll have the tools and habits you need to tackle the unique testing problems you'll face while building best-of-breed native iOS apps for your users. What You Need You'll need a Mac running at least Mac OS X Lion (10.7) and Xcode 4.6.

Test-Driven Development in Swift


Book Description

Leverage Swift to practice effective and efficient test-driven development (TDD) methodology. Software testing and TDD are evergreen programming concepts—yet Swift developers haven't widely adopted them. What's needed is a clear roadmap to learn and adopt TDD in the Swift world. Over the past years, Apple has invested in XCTest and Xcode's testing infrastructure, making testing a new top priority in their ecosystem. Open-source libraries such as Quick and Nimble have also reached maturity. The tools are there. This book will show you how to wield them. TDD has much more to offer than catching bugs. With this book, you’ll learn a philosophy for building software. TDD enables engineers to solve problems incrementally, writing only as much code as necessary. By decomposing big problems into small steps, you can move along at a fast pace, always making visible progress. Participate in the test-driven development journey by building a real iOS application and incorporating new concepts through each chapter. The book's concepts will emerge as you figure out ways to use tests to drive the solutions to the problems of each chapter. Through the TDD of a single application, you’ll be introduced to all the staples and advanced concepts of the craft, understand the trade offs each technique offers, and review an iterative process of software development. Test-Driven Development in Swift provides the path for a highly efficient way to make amazing apps. What You'll Learn Write tests that are easy to maintain Look after an ever-growing test suite Build a testing vocabulary that can be applied outside the Swift world See how Swift programming enhances the TDD flow seen in dynamic languages Discover how compiler errors can provide the same helpful guidance as failing tests do Who This Book Is For Mid-level developers keen to write higher quality code and improve their workflows. Also, developers that have already been writing tests but feel they are not getting the most out of them.




IOS Test-Driven Development by Tutorials (First Edition): Learn Real-World Test-Driven Development


Book Description

Learn how to test iOS Applications! iOS Test-Driven Development introduces you to a broad range of concepts with regard to not only writing an application from scratch with testing in mind, but also applying these concepts to already written applications which have little or no tests written for their functionality. Who This Book Is For This book is for intermediate iOS developers who already know the basics of iOS and Swift development but want to learn how to write code which is both testable and maintainable. Topics Covered in iOS Test-Driven Development The TDD Cycle: Learn the concepts of Test-Driven Development and how to implement these concepts within an iOS application. Test Expressions and Expectations: Learn how to test both synchronous code using expressions and asynchronous code using expectations. Test RESTful Networking: Write tests to verify networking endpoints and the ability to mock the returned results. Test Authentication: Write tests which run against authenticated endpoints. Legacy Problems: Explore the problems legacy applications written without any unit tests or without thought of testing the code. Breaking Dependencies into Modules: Learn how to take dependencies within your code and compartmentalize these into their own modules with their own tests. Refactoring Large Classes: Learn how to refactor large unweilding classes into smaller more manageable and testable classes / objects. One thing you can count on: after reading this book, you'll be prepared to write testable applications which you can have confidence in making changes too with the knowledge your tests will catch breaking changes.




iOS Code Testing


Book Description

Put into motion practical examples to master Test-Driven Development (TDD) and acceptance testing in Swift. This book uses a pragmatic approach to writing well-tested code and provides techniques that can be used to retrofit tests to legacy code bases. You'll be introduced to basic principles of TDD, such as Test First, Red-Green-Refactor, Remove Duplicate code, Dependency Injection, and Single Responsibility. Approaches covered include TDD, behavior-driven development (BDD), UI, and acceptance testing with common standard/open source frameworks. iOS Code Testing offers helpful instruction to teach iOS developers to retrospectively fit tests to legacy code, refactor legacy code so as to make the code more testable, install and configure a popular Swift BDD framework, practice BDD with Xcode, and create automated UI tests with Xcode.
