XSpec 
XSpec is a unit test and behaviour-driven development (BDD) framework for XSLT, XQuery, and Schematron. It is based on the Spec framework of RSpec, which is a BDD framework for Ruby.
XSpec consists of a syntax for describing the behaviour of XSLT, XQuery, or Schematron code, and some code that enables you to test the code against those descriptions.
