Indeed. The only time I have *ever* found to do this (I don't use TKinter ;)
is in the following scenario:

	# UnitTests.py

	import unittest

	from tests1 import *
	from tests2 import *

	if __name__ == '__main__':
		 unittest.main()

	# tests1.py

	import unittest

	class Test1 (unittest.TestCase):

		 def test1 (self):
		pass

	if __name__ == '__main__':
		 unittest.main()

	# tests2.py

	import unittest

	class Test2 (unittest.TestCase):

		 def test2 (self):
		pass

	if __name__ == '__main__':
		 unittest.main()

which allows me to perform each set of tests independently, and run them all
through a single command. Even so, it should probably specify the actual
names of the test cases in case there is a conflict somewhere, but that
would fail to pick up any new test cases.
