Mastering Cross-Platform Development with Xamarin

Overview of this book

The main goal of this book is to equip you with the required know-how to successfully analyze, develop, and manage Xamarin cross-platform projects using the most efficient, robust, and scalable implementation patterns. This book starts with general topics such as memory management, asynchronous programming, local storage, and networking, and later moves onto platform-specific features. During this transition, you will learn about key tools to leverage the patterns described, as well as advanced implementation strategies and features. The book also presents User Interface design and implementation concepts on Android and iOS platforms from a Xamarin and cross-platform perspective, with the goal to create a consistent but native UI experience. Finally, we show you the toolset for application lifecycle management to help you prepare the development pipeline to manage and see cross-platform projects through to public or private release.

Unit testing

The test-driven development (TDD) pattern dictates that the business requirements and the granular use-cases defined by these requirements should be initially reflected on unit test fixtures. This allows a mobile application to grow/evolve within the defined borders of these assertive unit test models. Whether following a TDD strategy or implementing tests to ensure the stability of the development pipeline, unit tests are fundamental components of a development project.

Figure 4: Unit test project templates

Xamarin Studio and Visual Studio both provide a number of test project templates targeting different areas of a cross-platform project. In Xamarin cross-platform projects, unit tests can be categorized into two groups: platform-agnostic and platform-specific testing.

Platform-agnostic unit tests

Platform-agnostic components, such as portable class libraries containing shared logic for Xamarin applications, can be tested using the common unit test projects targeting the .NET...
