That is exactly what the ‘TestCase.setUp’ method is for: to have the
test case class specify how its test cases will customise themselves.
class AVLTree_TestCase(unittest.TestCase):
tree = AVLTree
def setUp(self):
super().setUp()
self.test_instance = self.tree()
def test_empty_tree_is_false(self):
self.assertFalse(self.test_instance)
class LoremIpsumAVLTree_TestCase(AVLTree_TestCase):
tree = LoremIpsumAVLTree
class DolorSitAmetAVLTree_TestCase(AVLTree_TestCase):
tree = DolorSitAmetAVLTree
By not overriding ‘setUp’, the same routine will be called in the
subclass's instance also.

Yes, you'll need to consider inheritance and how the ‘unittest’ API
supports it.
