How can I tell CPAN Testers how to setup the environment for my tests?

I am writing tests that require external software (Amazon's local DynamoDB server) to be installed and running. Is there some way to tell CPAN Testers what to do?

Or should I just download the server and start it myself in the test setup? That would require Java 6.x or newer to be installed. So I think I am back to the first question.
