I am using Telerik Test studio with a visual studio plugin to create tests for my wpf application. In my test, I need to input different names and types of data...using "add new - excel" as a data source, is there a specific way to code my test in order to tell the test what data to use as its source? (for example -> I created an excel file with 5 columns of data and 3 rows. "name/id/amount/style/gender". I want to use name/style for the first test and id/gender for the next test. How can I do this?)
