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.
