description: Implement TDD for your React applications using Jest React Router Redux and GraphQL/Relay. Learn BDD and end-to-end acceptance testing with CucumberJS and Puppeteer. Many programmers are aware of TDD but struggle to apply it beyond basic examples. This book teaches how to build complex real-world applications using Test-Driven Development (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). Readers will practice systematic refactoring while building out their own test framework gaining a deep understanding of TDD tools and techniques. They will 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. The book covers refactoring codebases to use the React Router and Redux libraries. via TDD. Redux is explored in depth with reducers middleware sagas and connected React components. The book also covers acceptance testing using Cucumber and Puppeteer. The book is fully up to date with React 16.9 and has in-depth coverage of hooks and the act test helper. The target audience for this book is JavaScript developers who are looking to implement test-driven and behavior-driven approaches for their React applications.
