How to test random numbers within the range with the dieharder test suite

I'd like to test my randomness algorithm, base on some seeds and hashes. The main point, that my algo gives only interger numbers in range (from 2 to 12)/ And i'll d like to be sure that output will be really random. How can i test this with dieharder test suite? Is it possible to provide some range for example?

Thanks!
