Once you click "Create!" for a new form, you can preview its current state.

Go to your Form Summary page and click the preview link (top-right area by the form web address). Your form will open in a new window. Note that as a form editor, you can access the form regardless of the Who Can Respond settings.

Go ahead ... test out your form and submit it! You can delete all of your test submissions before you share the form's web address with your users. Learn how to delete your form data.
