Provision for test data for Development

Is there a provision for ‘test data’ that can be used for development only?
This may be from an archived database or constrained (delayed few queries per time period, etc).

The goal here is not to be charged for it. This provision will substantially help developers.

TIA,

If you setup your account & key and then contact commercial services with some information about your application, you can usually get some free queries to start out.
