What’s the difference between a free trial and test drive?

When you’re creating or editing a listing, the Trials tab asks whether you want to offer a free trial of Salesforce and your app or component. The free trial is a non-production Salesforce organization that includes your package and sample data. If a customer chooses to purchase the app or component instead of letting the trial expire, the organization becomes a production version. We recommend that you write a data cleanup script and include a button in your app or component that gives customers the option to remove sample data.

You can also choose to offer a test drive, which is a read-only version of your app or component that all customers taking the test drive log in to. Like a free trial, a test drive uses Developer Edition organizations that include sample data and whatever configuration options you choose.
