making unit tests with jena

[Thomas Marsh]

Hello jena folks,
We have a system that translates OWL into our own XML language and it 
uses Jena to do this.
We would like to write unit tests for our translation process so that we 
can verify our code correctness.  To do this, we would supply Jena 
domain objects (Resource, Statement, etc) to our code, and then verify 
that the objects that were returned are what we expected, given the 
input of a particular Jena object.

For example:  We have a factory that constructs an object given a 
Restriction. The test would be to supply a Jena Restriction that is a 
datatype restriction and then check that what our code returned is 
appropriate for a datatype Restriction. However, we need to 
programmatically create Jena resources (such as Restriction) and be able 
to make it a datatype restriction.  They want the resources to be 
standalone and with the minimal statements that we are able to specify. 
 We don't want to have to make an OWL file to do this.  Do you have any 
suggestions?
thanks!
