If the data driven check box is checked in Silk Test Classic test properties, each Silk Test Classic test will be repeated once for each data row in the external data source. By default, plan-based execution mode is used for data driven tests. This means that the results of all data rows will be listed under a single node in the .res result file. If execution mode is switched to script-based data driven in SccExecServerBootConf.xml, a result node will be created in the .res result file for each data row.
