My new job is completely focused on ASP.NET development and being a big believer in automated testing I've been investigating strategies for RIA's. I've found what I think is going to be a solution using Selenium which I'll blog more about later though I'm curious to know what other frameworks people are using? Basically, I don't want to overlook any potential candidates though at this point I'm very happy with Selenium.
What are you doing for automated testing of AJAX enabled Internet applications?
