What approach should be taken for testing in this repository?

Currently, there are two tools being migrated over to this repository: pelican-themes and pelican-import. The former doesn't have any unit tests in the main Pelican repository, but the latter does. To complicate things a little further, the tests for pelican-import currently imports various functions from support.py, but that's a discussion for another issue.

Should Travis just discover and run all the test files it finds under each "tool"?

That seems reasonable to me; is there a better way to do it?
