Mastering React Test-Driven Development

Key Features

• Learn the TDD process using the React framework
• Build complex, real-world applications with a pragmatic approach to TDD
• Use Cucumber for acceptance and behavior-driven development (BDD) testing, incorporating TDD in the wider team

Book Description

Many programmers are aware of test-driven development (TDD), but struggle to apply it beyond basic examples. This React book teaches you how to build complex, real-world applications using TDD. It takes a first-principles approach to the TDD process using plain Jest, and includes test-driving the integration of libraries including React Router, Redux, and Relay (GraphQL).

You will practice systematic refactoring while developing your own test framework, and will gain a deep understanding of TDD tools and techniques. You’ll also learn how to test-drive features such as client- and server-side form validation, data filtering and searching, navigation and user workflow, undo/redo, animation, LocalStorage access, WebSocket communication, and querying GraphQL endpoints.

Fully updated to React 16.9, this book will take you through refactoring codebases needed to use the React Router and Redux libraries via TDD. You’ll learn about Redux in depth, with reducers, middleware, sagas, and connected React components. This book will also cover acceptance testing using Cucumber and Puppeteer.

By the end of this book, you’ll have got to grips with best practices for TDD and be able to perform acceptance testing for your applications effectively.
