Overview of this book

While UI plays a pivotal role in retaining users in a highly competitive landscape, maintaining the same UI can be tricky if you use different languages for different platforms, leading to mismatches and un-synced pages. In this book, you'll see how .NET MAUI allows you to create a real-world application that will run natively on different platforms. By building on your C# experience, you’ll further learn to create beautiful and engaging UI using XAML, architect a solid app, and discover best practices for this Microsoft platform. The book starts with the fundamentals and quickly moves on to intermediate and advanced topics on laying out your pages, navigating between them, and adding controls to gather and display data. You’ll explore the key architectural pattern of Model-View-ViewModel: and ways to leverage it. You’ll also use xUnit and NSubstitute to create robust and reliable code. By the end of this book, you’ll be well-equipped to leverage .NET MAUI and create an API for your app to interact with a web frontend to the backend data using C#.

Unit Testing

Until now, we’ve been focusing on creating the app, but there is danger in going too far without introducing unit testing. In this chapter, we will focus on writing comprehensive and meaningful unit tests using best practices.

Test-driven development (TDD)

Some developers believe that unit tests should come before the code (TDD), but that is beyond the scope of this book.

Unit testing is crucial to creating robust applications and knowing that your app works before you ship it. It is also a critical aspect of debugging, telling you right away if something you just changed or added broke some aspect of your app.

To facilitate unit tests, you’ll want to use dependency injection so that you can mock up time-consuming services, such as APIs, databases, and so on. We’ll spend time with mocks, injected into our test classes, to ensure that we are processing data as intended.

The specific topics in this chapter are as follows:
