test.py should take an optional argument that indicates the subdirectory to search in

[ramou]

Right now, test.py just tests the whole repo. I wrote it myself when I had a single tool to test. If I, or anyone else, adds a new tool and they're testing locally, it'll be a huge pain and take a while as every other descriptor is tested. If I change it so you can run the tests on just your descriptors, that'll be much better.
