Description

React Testing Library (RTL) is a lightweight and easy-to-use tool for testing the document object model (DOM) output of components. This book will show you how to use this modern, user-friendly tool to test React components, reducing the risk that your application will not work as expected in production. The book demonstrates code snippets that will allow you to implement RTL easily, helping you to understand the guiding principles of the DOM Testing Library to write tests from the perspective of the user. You'll explore the advantages of testing components from the perspective of individuals who will actually use your components, and use test-driven development (TDD) to drive the process of writing tests. As you advance, you'll discover how to add RTL to React projects, test components using the Context API, and also learn how to write user interface (UI) end-to-end tests using the popular Cypress library. Throughout this book, you’ll work with practical examples and useful explanations to be able to confidently create tests that don't break when changes are made. By the end of this React book, you will have learned all you need to be able to test React components confidently.

I am thankful with the person that recommended this book to me, I started learning React just a few months ago and I can say that I am hooked with this framework, but I have to recognize that for me is really difficult to test the codes, find bugs :(, so I was struggling a lot to do it due to the nature of react but after I read the book I found the best way to test really complex components. The book is easy to follow with detailed instructions and great examples, well explained and written but also you gonna learn best practices, if you want to improve your testing skill as a developer don't lose the opportunity and read this book, it is really worthy, packed of knowledge and experience. Believe me you will not regret!

Scottie has a great way of explaining React development and testing. This book has been a huge help for me as I continue to learn React. It is easy to follow with detailed instructions and great examples. I would highly recommend this book to any developer that wants to improve their React testing skills.

Testing is one of those things that is teaching last. It is rare to find courses that include testing within the curriculum. But in the workplace, testing is a must, and this book will help you do it. I love that this book considers every detail. It considers the challenges that you face when working as a developer. And it teaches you from learn to test the DOM, through testing complex components to refactoring legacy applications and UI End-To-End with Cypress. I really would like to find a book that teaches React and testing at the same time.

And so I felt when I started working with this book. It is simple, not in depth explanations, yet useful to starting testing right away. I guess that if someone is looking for a more detailed book, this one might not be the right one, but I still think that it is a good fast intro for testing with RTL. It is true that the content you might find somewhere else too, but here you have it all in one place (again, basic, right?).

Amazon Customer Jun 08, 2021

I have watched countless videos, and trainings for React and by far this book has been the biggest help! It is easy to follow and contains extremely well detailed instructions and examples. The way Scottie explains these React concepts just makes sense! I would highly recommend this book to any developer and QA tester that wants to improve their React testing skills. This book is a great tool for any QA Automation Engineer looking to improve their testing skill, or just add another tool to their skill list.
