The spec repo includes test vectors. In order to make them easy to find for new devs and easy to maintain and keep up-to-speed with the spec, I actually have a special test class which contains all of the test vectors for the NUTs the library supports. Note that some of those are duplicated because the tests more appropriately belong in separate classes/packages, but again this is done in order to keep them easy to find and keep in sync with the spec repo.
The spec has added a number of new test vectors that are not currently in the test class, and this would be a good place to start in order to surface the things that need updating with the lib.
