The Ray Tracing Challenge - Including the tests from source code file in an open source repository?

Hi & thanks for the book!

I’m following the book building a ray tracer and would like to publish the code it as open source. I’m using the Cucumber tests from https://media.pragprog.com/titles/jbtracer/code/jbtracer-code.zip - Would be the tests be available/compatible with some open source licence? At least I couldn’t find anything with some searching?

If not, I could e.g. have a script that downloads & unzips the zip to proper location. Just a bit more convenient if I can add/enable the tests in the commits as I proceed.
