The MVVM Pattern in .NET MAUI

By: Pieter Nijs

Overview of this book

In today's fast-paced world of modern software development, teams need to be efficient, productive, and capable of rapidly adapting to changes to deliver high-quality products, making it crucial for developers to write maintainable and easy-to-test code. The MVVM Pattern in .NET MAUI helps you to thoroughly explore the Model-View-View Model (MVVM) design pattern. The chapters show you how this pattern helps in structuring code to embrace the separation of concerns, allowing for loosely coupled user interface and application logic, which ultimately empowers you to write more robust, maintainable, and testable code. The book also highlights .NET MAUI's capabilities and features, and enables you to delve into the essential components within the framework that facilitate the application of the MVVM pattern. With the help of a sample application, this definitive guide takes a hands-on approach to walk you through both the essential and advanced usages of the MVVM pattern to ensure that you successfully apply the practical aspects of the pattern to your .NET MAUI projects. By the end of this book, you’ll have gained a comprehensive understanding of the MVVM design pattern and its relevance in the context of .NET MAUI, as well as developed the skills needed to successfully apply it in practice.

Setting up a unit test project

In this section, we will be walking through the steps of setting up a unit test project and creating a first test. We’ll be using xUnit in this section. We’re not going to get all tangled up in the tiny details of this specific library because there are tons of other awesome ones. No matter what you choose, the big takeaways should stick with you. So, without further ado, let’s dive in and start setting the stage for effective ViewModel testing!

Creating a unit test project

Let’s start by creating an xUnit Test project. In xUnit, one of the things I appreciate is its simplicity. Test classes and methods are just normal classes and methods, without the need for special base classes or complex setups. Here’s how:

  1. In the Solution Explorer in Visual Studio, right-click Solution ‘Recipes App’ and select Add | New Project….
  2. In the Add a new project dialog, type xunit in the search box...
