ASP.NET Core 3 and React

By: Carl Rippon

Overview of this book

Microsoft's ASP.NET Core is a robust and high-performing cross-platform web API framework, and Facebook's React uses declarative JavaScript to drive a rich, interactive user experience on the client-side web. Together, they can be used to build full stack apps with enhanced security and scalability at each layer. This book will start by taking you through React and TypeScript components to build an intuitive single-page application. You’ll understand how to design scalable REST APIs that can integrate with a React-based frontend. You’ll get to grips with the latest features, popular patterns, and tools available in the React ecosystem, including function-based components, React Router, and Redux. The book shows how you can use TypeScript along with React to make the frontend robust and maintainable. You’ll then cover important .NET Core features such as API controllers, attribute routing, and model binding to help you build a sturdy backend. Additionally, you’ll explore API security with ASP.NET Core identity and authorization policies, and write reliable unit tests using both .NET Core and React before you deploy your app to the Azure cloud. By the end of the book, you’ll have gained all the knowledge you need to enhance your C# and JavaScript skills and build full stack, production-ready applications with ASP.NET Core and React.

Adding Automated Tests

Now, it's time to get our Q and A app ready for production. In this chapter, we are going to add automated tests to the frontend and backend of our app, which will give us the confidence to take the next step: moving our app into production.

First, we will focus on the backend and use xUnit to implement unit tests on pure functions with no dependencies. Then, we'll move on to test controllers and mock out their dependencies using Moq.

Next, we will turn our attention to testing frontends with the popular Jest tool. We will learn how to implement unit tests on pure functions and integration tests on React components by leveraging the fantastic React Testing Library.

Then, we will learn how to implement end-to-end tests with Cypress. We'll use this to test a key path through the app where the frontend and backend will be working together.
