Telerik have just announced their Test Studio recording / automation software now supports MonoTouch.
Test Studio for iOS now supports testing of MonoTouch applications out-of-the-box. All you need to do is configure your MonoTouch project with our testing extension, and it becomes testable. You can do this without ever leaving MonoDevelop, Xamarin's MonoTouch IDE.
Looks like an interesting tool - record the taps / interactions, and play them back against your app, so you can test even the most in-depth, intricate apps quickly and easily. It's free, too!
Xamarin's Mike Bluestein is also talking at the launch webinar on August 16th, so have a listen if you are interested.
