Some prelimary tests seems to suggest this idea might work here too.
Starting from this:
class Test_AVLTree(unittest.TestCase):
def test_empty_tree_is_false(self):
instance = avltree()
self.assertFalse(instance)
Changing it into this:
def MakeAVLTest(avltree):
class Test_AVLTree(unittest.TestCase):
def test_empty_tree_is_false(self):
instance = avltree()
self.assertFalse(instance)
return Test_AVLTree
AVLTest = MakeAVLTest(avltree)
MyTreeTest = MakeAVLTest(mytree)
Seems to work
