This Episode is part five in our (probably ongoing) series on service oriented architecture. In this episode we talk to Nico Josuttis, who has recently published a book on this topic. As its title "SOA in Practice" suggests, it is a very pragmatic book based on Nico's experience as architect and project lead in a number of enterprise-level projects - not all of them had been called SOA, since they at the time the term was not yet coined. The episode discusses some technical aspects of SOA (such as loose coupling, messaging and ESBs), but mainly focusses on non-technical aspects of implementing an SOA.

In this episode we talk with Gerard Meszaros about problems and challenges doing unit testing in real-world projects. Starting from a short discussion about the importance of automated unit testing we spend most of this episode to talk about every day problems doing unit testing and how those problems can be solved. Based on this book on xunit testing patterns, Gerard talks about his experiences with unit test smells as an analogy to code smells. He describes an impressive set of unit testing patterns to overcome those difficult testing situations and illustrates them with nice examples everybody doing unit testing will feel familiar with.

In this episode Eberhard Wolff speaks with Jürgen Höller, the co-found of the Spring framework. Spring is a tremendously successful Java framework so they discuss the design of large frameworks and the issues that arise in the evolution. Jürgen explains the management of dependencies in the framework, how to structure such a framework, how to offer compatibility for the existing user base while evolving the framework and the role of metrics during development.
