Hi Scott,

The Selenium IDE is not fully suitable for Telerik UI for ASP.NET AJAX controls testing.

Presently, we are using Telerik Test Studio as well as the free Telerik Test Studio Testing Framework for test automation.

You may find information on how to automate with Selenium IDE in previously published blog and forum posts. I suggest you to check the Selenium Scripts for RadControls, Firebug and XPath Support blog post and the following forum thread concerning RadComboBox testing with Selenium.

I would recommend you, however, to try the Testing Framework and Test Studio products, since they provide a rich API that expose numerous properties and methods to help you easily build non-brittle, maintainable functional tests:

• The free Telerik Testing Framework which helps you automate AJAX, Silverlight and WPF applications using coded steps for free.
• WebUI Test Studio which has the options to record, execute and debug functional tests with the Visual Studio environment.

You could also find the following blog post interesting and more information in the following article TestStudio-versus-VS-Comparison. 


Best regards,
Rumen
