Agile development practices and good Object Oriented Design principles are supposed to enable unending, gentle modification of an existing codebase. Is this really true, though? In the course of 5+ years developing and evolving an open source framework, I’ve learned a lot of painful lessons about the issues that retard code extensions and modifications. I’ve also learned a little bit about the design decisions that dramatically increased my ability to extend the code. In this talk I’ll show several instances of how failing to heed design fundamentals introduced code …

In this screencast we will demonstrate how to use the Object Builder pattern to create and setup objects for tests. In the first part we discussed how to introduce the base class for the unit tests to improve readability and cleanness of code.

Starting to unit test your first project is difficult, where to start? What to test? How do you even get started? In this session, Ben starts from scratch and implements an ASP.net 2.0 application using test driven development techniques. The application will have to deal with real world situations such as databases, web services and even some users! Ben will demonstrate how to design the application for testability and how unit testing and mock frameworks can make your life easier and your tests …
