Testing pre-loaded questionnaire

SS makes it easy to test your questionnaires. You can use the web interface or the tester app. But, we are trying to deploy a pre-loaded questionnaire. And testing it is a pain. We have to deploy the questionnaire on the SS server with some data to test. And every time we make any change to the questionnaire, this needs to be redone. Its a problem when the change includes addition/change of a pre-loaded variable as the new data needs to compiled.

Is there another way to test a pre-loaded questionnaire in designer/tester app?

How about testing scenarios?

Thank you. Will explore this.
