Overview of this book

.NET Core is one of the most popular programming platforms in the world for an increasingly large community of developers thanks to its excellent cross-platform support. This book will show you how to confidently use the features of .NET 5 with C# 9 to build robust enterprise applications. Throughout the book, you'll work on creating an enterprise app and adding a key component to the app with each chapter, before ?nally getting it ready for testing and deployment. You'll learn concepts relating to advanced data structures, the Entity Framework Core, parallel programming, and dependency injection. As you progress, you'll cover various authentication and authorization schemes provided by .NET Core to make your apps and APIs secure. Next, you'll build web apps using ASP.NET Core 5 and deploy them on the cloud while working with various cloud components using Azure. The book then shows you how to use the latest Microsoft Visual Studio 2019 and C# 9 to simplify developer tasks, and also explores tips and tricks in Visual Studio 2019 to improve your productivity. Later, you'll discover various testing techniques such as unit testing and performance testing as well as di?erent methods to deploy enterprise apps. By the end of this book, you’ll be able to create enterprise apps using the powerful features of .NET 5 and deploy them on the cloud.

Understanding unit testing

Unit testing is a way to test the smallest isolated unit of an application. It is an important step in software development that helps isolate a problem early.

Unit testing has a direct impact on the quality of the software we build. It is always recommended to write a unit test as soon as you write any method. If we follow the methodology of Test-Driven Development (TDD), we write the test case first and then proceed to implement the functionality.

In the next section, we will learn about creating unit tests and running them from Visual Studio.

Unit testing in Visual Studio

We chose to use Visual Studio as it has powerful tooling to create and manage test cases.

With Visual Studio, we can create, debug, and run unit test cases. We can also check the code coverage of the tests that are executed. Additionally, it has a Live Unit test feature, which runs unit test cases while we modify the code and shows the results in real time.
