Learn test-driven and behavior-driven development techniques that will give you greater confidence when building React applications Key FeaturesExplore the TDD process, how it works, and why it will help you write maintainable React appsDevelop a component testing framework from scratch, which will help you understand the mechanics of good unit testingReduce complexity by using unit tests and end-to-end acceptance tests to drive the design of your appsBook Description Test-driven development (TDD) is a programming workflow that helps you build your apps by specifying behavior as automated tests. The TDD workflow future-proofs apps so that they can be modified without fear of breaking existing functionality. Another benefit of TDD is that it helps software development teams communicate their intentions more clearly, by way of test specifications. This book teaches you how to apply TDD when building React apps. You'll create a sample app using the same React libraries and tools that professional React developers use, such as Jest, React Router, Redux, Relay (GraphQL), Cucumber, and Puppeteer. The TDD workflow is supported by various testing techniques and patterns, which are useful even if you're not following the TDD process. This book covers these techniques by walking you through the creation of a component test framework. You'll learn automated testing theory which will help you work with any of the test libraries that are in standard usage today, such as React Testing Library. This second edition has been revised with a stronger focus on concise code examples and has been fully updated for React 18. By the end of this TDD book, you'll be able to use React, Redux, and GraphQL to develop robust web apps. What you will learnBuild test-driven applications using React 18 and JestUnderstand techniques and patterns for writing great automated testsUse test doubles and mocks effectivelyTest-drive browser APIs, including the Fetch API and the WebSocket APIIntegrate with libraries such as React Router, Redux, and Relay (GraphQL)Use Cucumber.js and Puppeteer to build Behaviour- Driven Development (BDD) style tests for your applicationsBuild and test async Redux code using redux-saga and expect-reduxWho this book is for This book is for frontend developers who are looking to improve their testing practices and increase the quality and maintainability of their applications. To make the most of this book, you'll need knowledge of the JavaScript programming language.

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.
