Do you mean you want someone to test the survey for you? If so, no you don't need to publish. Give them the preview link.

Where is the preview link? If I published the survey, what might happen and how could I retract the published survey? Thanks a lot!

Hi Songli! If you have not yet already, I’d recommend reviewing this support page on Testing Active Surveys to help you get started. If you still have questions after reviewing the linked support pages, you'll want to reach out to the  Support team, as they are best equipped to help answer questions and provide support! :)

Thanks! I got it.
