Hello Jan,
Thanks for trying Test Studio. Test Studio comes with a set of what we call "
translators" that are tailor made to recognize and give you additional functionality for most of our Telerik
WPF controls. Our online documentation goes into great detail on what you can do with these translators. Test Studio does recognize 3rd party controls as well. It can identify their elements and act on them. However, Test Studio does not have translators in place for 3rd party controls, so it may not identify the entire control as such. For example, Test Studio will recognize a text input box, but not that it is part of a more complex 3rd party control.
Please let us know if we can help you further.
All the best,
Plamen
the Telerik team
