Growing Object-Oriented Software, Guided by Tests by Steve Freeman and Nat Pryce is a book I was long waiting for. GOOS demonstrates the techniques and highlights the patterns as they show up in an application grown through the book. An albeit small but a real world project is being developed from scratch in a way were tests play as important a role as object-oriented design.

It is an excellent opportunity to see how two skilled developers are growing application. The authors work in TDD in a style characterised by extensive mocking to avoid breaking encapsulation. In design they use fine grain classes. All together the style demonstrated in the book is very consistent.
