Overview of this book

Developed by Facebook, React is a popular library for building impressive user interfaces. React extends its capabilities to mobile platforms using the React Native framework and integrates with popular web and mobile tools to build scalable applications. React Projects is your guide to learning React development by using modern development patterns and integrating React with powerful web tools, such as GraphQL, Expo, and React 360. You'll start building a real-world project right from the first chapter and get hands-on with developing scalable applications as you advance to building more complex projects. Throughout the book, you'll use the latest versions of React and React Native to explore features such as routing, Context, and Hooks on multiple platforms, which will help you build full-stack web and mobile applications efficiently. Finally, you'll get to grips with unit testing with Jest and end-to-end testing with Cypress to build test-driven apps. By the end of this React book, you'll have developed the skills necessary to start building scalable React apps across web and mobile platforms.

Unit testing components

Unit testing is an important part of your application, since you want to know that your functions and components behave as expected, even when you make code changes. For this, we're going to use the React Testing Library, an open source testing package for React applications that was created by the React community. With the React Testing Library, you can test assertions – for example, whether the output of a function matches the value you expected.

To get started, we don't have to install anything; it's part of Create React App. If you look at the package.json...
