Qiu J. Test-Driven Development with React...Applications 2021 torrent

Textbook in PDF format

Implement TDD for your React applications using Jest, React Router, Redux, and GraphQL/Relay, and learn BDD and end-to-end acceptance testing with CucumberJS and Puppeteer
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
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.
What you will learn
Build test-driven applications using React 16.9+ and Jest
Design complete web applications using a variety of HTML input elements
Understand the different types of test double and when to apply them
Test-drive the integration of libraries such as React Router, Redux, and Relay (GraphQL)
Get to know when to be pragmatic and how to apply TDD shortcuts

Who this book is for
This book is for JavaScript developers and React programmers who are looking to implement test-driven and behavior-driven approaches for their React applications. A basic understanding of the Git commands will be helpful.
