Learn test-driven and behavior-driven development techniques that will give you greater confidence when building React applications
Key Features
- Explore the TDD process, how it works, and why it will help you write maintainable React apps
- Develop a component testing framework from scratch, which will help you understand the mechanics of good unit testing
- Reduce complexity by using unit tests and end-to-end acceptance tests to drive the design of your apps
Book 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 learn
- Build test-driven applications using React 18 and Jest
- Understand techniques and patterns for writing great automated tests
- Use test doubles and mocks effectively
- Test-drive browser APIs, including the Fetch API and the WebSocket API
- Integrate 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 applications
- Build and test async Redux code using redux-saga and expect-redux
Who 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.

We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
