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.
