Overview of this book

<p>You can create native mobile applications using the Xamarin Forms platform for the three major platforms iOS, Android, and Windows Phone. The advantage of this is sharing as much code as you can, such as the UI, business logic, data models, SQLite data access, HTTP data access, and file storage across the three major platforms.</p> <p>This book provide recipes on how to create an architecture that will be maintainable, extendable, use Xamarin Forms plugins to boost productivity, customize your views per platforms, and use platform-specific implementations at runtime.</p> <p>We start with a simple creation of a Xamarin Forms solution with the three major platforms. We will then jump to XAML recipes and you will learn how to create a tabbed application page, and customize the style and behavior of views for each platform. Moving on, you will acquire more advanced knowledge and techniques while implementing views and pages for each platform and also calling native UI screens such as the native camera page.</p> <p>Further on, we demonstrate the power of architecting a cross-platform solution and how to share code between platforms, create abstractions, and inject platform-specific implementations. Next, you will utilize and access hardware features that vary from platform to platform with cross-platform techniques. Well then show you the power of databinding offered by Xamarin Forms and how you can create bindable models and use them in XAML. You will learn how to handle user interactions with the device and take actions in particular events.</p> <p>With all the work done and your application ready, you will master the steps of getting the app ready and publishing it in the app store.</p>

Creating acceptance tests with Xamarin.UITest


Outside-In testing is the acceptance testing we are performing to make sure that the application meets the specifications. These tests start from the user interface testing and might go to the bottom of the architecture. These behavior tests are responsible for testing the user interface functionality and behavior. In this section, we will look into the Xamarin.UITest acceptance testing framework and create a cross-platform UITest for the Android and iOS platforms just like a user would interact with it.

Xamarin.UITest is based on NUnit, and on the open source framework Calabash, one of the world's most popular behavior-driven development acceptance frameworks for mobile applications. Beware, though, as these are not unit tests.

In this recipe, we are using Xamarin Studio on a Mac. Creating a Xamarin.UITest cross-platform project is supported in Visual Studio; however, you will be able to test your Android tests only. iOS UI testing is not yet...
