Well, actually, in the enthought tools suite we use setuptools for
packaging (I don't want to start a controversy, I am not advocating the
use of setuptools, just stating a fact) and nose for testing, and getting
"setup.py test" to wrok, including do the build test and download nose if
not there, is a matter of addig those two lines to the setup.py:

    tests_require = [
        'nose >= 0.10.3',
        ],
    test_suite = 'nose.collector',

Obviously, the build part has to be well-tuned for the machinery to work,
but there is a lot of value here.
