Unlicensed files

Hello!

First of all, thank you so much for nice and easy test framework. Sadly, it is unclear for me under which rules I (or someone else) may use automatic tests located in the "test" directory. May one redistribute them or compose a derivative work? In other words, are the terms of use compatible with [free software (open source)][1]?

It would be great if you (as copyright holder) issue a public statement about how one may use these tests. Please either add to each file in the "test" directory a comment with a copyright notice and an applied license, or commit the license into a file at the repository root.

In any case, thank you again for the test framework.
