I am very new to VSTS. Unable to save data to database when trying to execute data driven test. We have number of online surveys and test data sets given by our science department. Our application calculate scores and saves to database. Here I am trying to verify test data sets(.csv file provided by science)to data base. System generates session id when ever we open survey form. But it looks like VSTS is using only one session id for all iterations. Thats not correct either.
