Before showing an interaction for your website visitors, you can easily test the interaction inside the giosg Interaction Builder. Use the preview-page to click on different buttons and make sure that the actions for each button is correct. You can also add your website as a background and make sure that the look and feel of the interaction fits your brand and your website.
You can also test the interaction on a hidden URL on your webpage. Make up a URL string (such as #test) and add that to the "When webpage address contains" field on the Publish page. After publishing you'll be able to see the interaction on the website by adding your # url string to the website url (for example www.giosg.com/#test).
Watch the video below to get an idea of how you can test your interactions!
