Thank you for reaching us out.
Test Studio provides built-in translators
for the Telerik controls which currently are available in record mode for Internet Explorer only. The good news is we are working on the implementation of these for Firefox and Chrome recording as well.
Except including the feature for all supported for recording browsers we will also extend the amount of Telerik controls covered by these translators. All these new features will be available with our upcoming release which is planned for the end of May.
I hope the above information will worth it to continue exploring Test Studio. In case you still face troubles with recording in IE as well I would like to kindly ask you to share a sample app or point to a sample on our Kendo demo pages which I could use for testing on my end.
Please do not hesitate to contact me back! Thanks!
