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.

Questions

The following questions will test your knowledge of the topics that were covered in this chapter:

  1. We have the following xUnit test method, but it isn't being picked up by the test runner. What's wrong?
public void Minus_When2Integers_ShouldReturnCorrectInteger()
{
var result = Calc.Add(2, 1);
Assert.Equal(1, result);
}
  1. We have a string variable called successMessage in a xUnit test and we need to check that it contains the word "success". What method in the Assert class could we use?
  2. We have created some Jest unit tests on a List component in a file called ListTests.tsx. However, when the Jest test runner runs, the tests aren't picked up. Why is this happening?
  3. We are implementing a test in Jest and we have a variable called result that we want to check isn't null. Which Jest matcher function can we use?
  4. Let's say we have a variable...
