Model Based Testing anyone?

Hi,

 

I am using model based testing for easing the increase of test coverage.

I am generating testscripts from "requirement" models, which are imported into the TC project, and then executed.

The models are represented in Graphml, and traversed by an external tool, which output are converted into scripts.

 

My interrest is, if anyone is using Model Based Testing other than me? and if so. Then how? Willing to share experience :-)
