It is difficult to maintain agile practices when building a large GUI application. Unit testing code that accesses the native interface API is problematic. Keeping the program logic separated from it is key to using TDD practices through to the end of your project. Presenter First (PF) is a scalable strategy for producing fully unit tested GUI applications directly from user stories in a TDD fashion without the expense of traditional GUI testing tools. PF is about composing applications into cooperating Model-View-Presenter (MVP) triads using TDD and driving development from user stories through the presenters. This approach to development makes logic, class and module decoupling easier to achieve and maintain. The code that touches the GUI is kept as simple as possible. In this session you will pair with the speaker and other participants in the construction of a GUI application, using and learning about the benefits of MVP-PF as we go. A laptop with Visual Studio is recommended for following along with and completing the exercises.

After working as an independent consultant as a means of paying for school, Scott began working as a developer full time in the late 80s. He has lead or participated in a wide range of projects including Kitchen & Bath design, Automotive job costing, Explosives detection, Golf and hockey league management, Internet-based file sharing, and several applications in the textile and apparel design field. Scott has spent the last two years exploring and refining Test Driven Development practices for large applications on several platforms, including C#, C++, Java, and HTML/Javascript.
