Responsibility Driven Design met jMock

Responsibility Driven Design is een term bedacht door Rebecca Wirfs-Brock en gaat over goed OO ontwerp. Bij OO ontwerp is het de kunst om de juiste verantwoordelijkheid bij de juiste objecten te leggen en zo een helder ontwerp met losse koppeling en hoge cohesie te bouwen.

Test Driven Development (TDD) stuurt je die richting op, maar nog niet helemaal. Het helpt om los gekoppelde elementjes te krijgen, aangezien te veel koppelingen het test-code-refactor ritme in de weg zitten.

Testen met mocks gaan een stap verder. De focus verschuift van de toestand van objecten naar interacties - de boodschappen die tussen objecten worden verstuurd. Testen met mocks legt dus de nadruk op gedrag. In deze sessie met live programmeer-demonstratie laten we zien hoe het jMock framework (www.jmock.org) je helpt om niet state-based maar responsibility-based te ontwikkelen en hoe dit het tell, don't ask principe afdwingt.

  • Leer hoe mockobjecten je TDD-discipline een stap verder kunnen brengen
  • Zie in hoe gedrag-gestuurde tests je ontwerp kunnen verbeteren
  • Leer een domeinspecifieke taal voor het beschrijven van verwachtingen op gedrag van objecten

Rob Westgeest 
QWAN
After years of experience with Object Oriented Software Development with UML, several development processes and project approaches as developer, trainer and project leader, Rob worked on his first XP project in 2000. And with great success! He supports projects and people in the application of agile practices, principles and values since then. Rob develops himself and others continuously by visiting, organising and hosting workshops at conferences and user group meetings like SPA, XP Days, XP-NL and Agile Open. Rob explains hard problems in a simple way, so the problems and the solutions are easy to fathom. He is able to let others experience what he learned quickly, and so doing guides teams around pitfalls. His enthusiasm and sense of humour makes it a great pleasure to work with Rob.
