Experienced mobile developers know to put as much logic as possible into an app's back-end for maintainability and testability. But what about logic tied to the user interface like interactivity and navigation? Instead of using event handlers, delegate callbacks, and a tight coupling between app layers, ReactiveUI allows you to handle user interactions for your front end View through a LINQ-like syntax of subscribing to status changes in your back-end ViewModel. This makes it easier to test your app by testing your ViewModels independently of their Views with less reliance on UI testing frameworks.

Mobile devs are used to testing the JSON or XML that comes across the wire, the standalone logic of their app backend, and the whole app. But what about the gaps between testing the API output, unit testing your Models and ViewModels with mocks, and testing through the UI? This session will cover: * Testing the translation of API data into app Models * Testing how ViewModels use and cache your app Models * Testing your API library for fault-tolerance and unusual API responses
