The times that apps were mainly developed by a single developer on their spare time are over. For an increasing number of companies app development is serious business. Working together with a handful of team members means you’ll have to share responsibilities with regards to stability and quality. Most developers already know about unit testing and continuous integration, little have yet applied these techniques to Windows Phone development. In this session we’ll look at some of the difficulties, solutions and tools that can help with testing Windows Phone applications. Together with Olaf Conijn we’ll take a look at: - different approaches to unit testing Windows Phone applications. - how to set up continuous integration server - tools and frameworks that can help make your app more testable. - how to deal external components such as the Web Requests and database access. This is a technical session. At times we’ll have to dive deep into concepts such as AppDomain’s and build scripts to understand what’s really going on with our applications.
