GivWenZen is a framework that builds upon FitNesse and Slim to allow the user to exploit the Behavior-driven Development technique of expression, using the Given-When-Then vocabulary to describe tests. These test descriptions are also created using the FitNesse wiki facility, of expressing the tests as plain text contained in tables in a wiki page.

The idea is simple and straightforward, and follows up with what we have been doing with FitNesse, but this time instead of writing acceptance tests giving a table of values, we will use the three Behavior-driven Development magic words, Given-When-Then, to describe our scenarios.

Firstly, let's install FitNesse with GivWenZen. Download the full distribution from its download list page at http://goo.gl/o3Hlpo. Once unzipped, the GivWenZen JAR starts up exactly the same way as FitNesse did (because it's just a modification on top):

$ java -jar /lib/fitnesse.jar -p 8900
