Presented at www.agiletestingdays.com 2012
Example at https://github.com/andreassimon/dsls-for-customer-integration

Learn how to involve your customer not only through acceptance tests, but also through custom-made programming languages focused on your particular domain.

An important point in agile projects is the development of a common “project jargon” from the existing business terminology. Based on this vocabulary you can create a simple, small programming language on your own. Such a Domain-Specific Language enables you to involve your customer not only by writing examples, but also by developing parts of the production code together. Andreas will give you a glimpse of what you can achieve with modern language tools.
