Can anyone point me to the subject matter please? Thanks a tonne.!
QAforums.com has all that you might need on this.
First, I went to the Automated Test tools forum, and from there to the FAQs. They had the answer in their white papers section.
This was including a comparison white paper that might be of interest to you.
I hope this is what you are looking for,
