Questionnaires: how do I view and fill them out as if I were a patient?

Questionnaires: how do I view and fill them out as if I were a patient?

I want to view and fill out all my questionnaires as if I were a patient after I create them to ensure they work properly and they flow just like I want them to?

Dummy patient
Ideally I would log in as the dummy patient via the patient portal (after I send him the questionnaires) and view and fill them out on his behalf. This would provide valuable information. But I LACK access to his patient portal sign in information.

Help!
