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#.

Summary

In this chapter, we reviewed the critical importance of writing unit tests and comprehensively testing your program. In a nutshell, unit tests allow you to code with confidence, knowing that if you make a change and it breaks something seemingly unrelated, you’ll find out about it immediately.

We saw that, at times, your unit test must interact with slower external systems (APIs, databases, and more) and that you can keep your subsecond response time by using mocks; the mocking library we chose is NSubstitute, though there are other free mocking systems as well (a very popular one is Moq).

In order to facilitate using mocks, we looked at dependency injection and briefly reviewed the role of IoC containers. In the next chapter, Consuming a Rest Service, we will look at getting our data from a cloud-based (Azure) service, rather than mocking the data.
