Responsibility-Driven Development, Test First

• Presenter: Steve Freeman
• Type: Tutorial
• Duration: 90 minutes
• Audience: Developers with some experience of Test-First

Abstract

This tutorial is for programmers who would like to understand more about Test-First programming.

It will demonstrate how to use unit tests to help you think about what each object does and how it interacts with its neighbours. You will learn about Responsibility-Driven Design, using techniques such as CRC cards and Mock Objects. You will see how this approach improves the code as it helps to clarify ideas and concepts, and encourages more focussed design. I will include an introduction to the jMock framework, showing the motivations for its design and the process of how to use it to drive a design.
