I wrote the below code

    fname = os.path.basename(source)
    def test_read(self):
        phx = PhyloXMLIO.read(source)
        self.assertTrue(phx)
        self.assertEqual(len(phx), count[0])
        self.assertEqual(len(phx.other), count[1])
    test_read.__doc__ = ('Read    %s    to    produce    a    phyloXML    object.' % fname)
    return test_read

What's a good function header?
