Summary

In this chapter, we walked through a practical example of TDD in action. Although TDD is often accompanied with a small amount of up-front UML diagramming, we deliberately avoided that in the example. This was to contrast the techniques used to create a design using vanilla TDD with the techniques used to create a design using up-front UML diagramming.

In the next chapter, we hit the Rewind button and repeat the example using TDD plus some up-front analysis and design (A&D). Naturally, we use ICONIX Process as the A&D methodology.
