Consider the following sample Angular login form: http://www.tutorialspoint.com/angularjs/angularjs_login_application.htm Recording this as a Test Studio UI test doesn't work because TS' non-simulated typing steps will not trigger the angular input events. And so the 'Sign in' button will remain disabled. The workaround is to trigger the event manually in code with something like this: Actions.InvokeScript("angular.element(" + element.ClientSideLocator + ").val('" + text.Replace("'", "\\'") + "').triggerHandler('input')") This exact issue has been discussed: http://www.telerik.com/forums/will-there-be-support-to-handle-angular-applications And you would have to add a coded step after every input typing step. It's very inconvenient. Test Studio should detect whether this is an angular control and then automatically arrange for the script to triggering behind the scenes. The same way it works for HtmlSelect: http://screencast.com/t/DvWbwjMv5 You can simply set the step to SimulateRealType but this is not a great solution. Angular is extremely popular and by not supporting it properly is really hurting TS' appeal.
