Watir, Watir Everywhere
After getting a link from Dave Thomas, I checked out the link below. Following some leads from that blog, I uncovered Watir: Web Application Testing in Ruby. Watir is designed to drive Internet Explorer (yes, that Internet Explorer) using a Ruby script.
This sounds like a dream addition to the testing stack. Especially if this is a way to slip Ruby in the door. Stay tuned for more details.
