Have a look at the unittest module in the standard library
http://docs.python.org/lib/module-unittest.html
It can do the bookkeeping for you:
>>> import unittest
>>> class TestCase(unittest.TestCase):
... def testCase1(self):
... print "first"
... def testCaseN(self):
... print "last"
...
>>> unittest.main()
first
.last
.
