There are some great tests out there: Draft Special Publication 800-90B - National Institute of Standards

In particular the min-entropy, partial collections, Markov (useful for non-IID sources), collisions, and compression tests.

The issue with the Markov test is the constraint on bit size of the sample.

Updated:

These tests only measure output. They don't measure the underlying entropy that was used to generate the data. You can take completely non random data and make it look perfectly random according to these tests (or any tests).

The issue with the Markov test is the constraint on bit size of the sample. Too bad, it would be handy…

Theres some great tests listed here:

http://csrc.nist.gov/publications/drafts/800-90/draft-sp800-90b.pdf

In particular the min-entropy, partial collections, markov (useful for non iid sources), collisions, and compression tests.

The issue with the markov test is the constraint on bit size of the sample. Too bad, it'd be handy..

Selecting this as the answer as this is exactly what I was looking for..
