In this blog post we’ll see how to go beyond code smells. We’ll see how to identify design smells and inappropriate coupling in the technical architecture. We’ll define detection strategies for common design smells (like God Class and Feature Envy) and implement them using NDepend. Last but not least, we’ll see how we can define fitness functions that detect dependency violations in our application’s architecture.
