How to test random numbers?

by

With most tests you can supply a large file of random numbers (integer or floating point) and run various tests on that sample file. DIEHARD worked that way, if I remember correctly and some others do, too. If you really want to see your generator fail, you could try using TestU01 by Pierre L’Ecuyer which has enough tests in it to let nearly every generator fail at least one test 🙂

Still, for most test suites there is extensive documentation, at least I know this for DIEHARD, the test suite from NIST SP 800-22 as well as DieHarder and TestU01 (links go to the docs). The methods for supplying random numbers to test are usually different but mentioned in the respective documentation.
