Is there a unittest suite for this code?

[pombredanne]

I may be blind but I could not find actual unit tests, which is surprising for code of this complexity. Can you point me to a unit test suite that I might have missed?
Thank you!

Technically, yes, but unfortunately not in a way that's useful to you. The test suite uses a bunch of google-internal stuff, so the tests get stripped as part of the process that exports this library to GitHub.
