Test Studio expects an anchor under KendoTab. In case of missing it throws an exception: ArtOfTest.Common.Design.Exceptions.ExecutionException: Invalid tag name 'span' for this control. Control was expecting 'a' ---> System.ArgumentException: Invalid tag name 'span' for this control. Control was expecting 'a' at ArtOfTest.WebAii.Controls.Control.CreateInstance[TControl](Element e, Boolean throwIfNull) at Telerik.TestStudio.Translators.KendoUI.TabStrip.KendoTabSelect.Execute(Browser browser) at ArtOfTest.WebAii.Design.Extensibility.HtmlActionDescriptor.Execute(IAutomationHost autoHost) at ArtOfTest.WebAii.Design.Execution.ExecutionEngine.ExecuteStep(Int32 order) The workaround is to disable KendoTabStrip translator and record the step again. Steps to reproduce and access to the application are in the internal description.
