One of the new features in DevTest 10.1 is the ability to create virtual services from Swagger in DevTest Portal. Watch this video for a demonstration.
By the way, the DocOps space for DevTest 10.1 now has 20 videos. You can easily find them by going to the DocOps space and doing a search for the term "video".
Thanks for doing this Jeff. I have added this video to the Upgrade Center here - DevTest Solutions Upgrade Center
