Testing Rich Domain Models

A domain model encapsulates data and behavior together into expressive domain objects. Testing is not only important for verifying domain behavior, but also measuring the suitability of the design. In this session, Chris will show you testing techniques that build confidence in your code and help you improve your design.

A rich domain model is an excellent way to organize complex business logic. It can make the code easier to understand and maintain. Using a domain model can even make testing easier. Sadly, many developers do little or no automated testing and so do not fully benefit from using a domain model. The quality of their code gradually declines, development becomes increasingly more difficult and they often have to throw the code away and start over. In this presentation you will learn some simple yet effective ways to test a domain model. We describe how to overcome some of the common obstacles to writing tests. You will learn testing techniques that you can easily apply to your existing domain model.
