This is not necessarily a justification, but many tests construct
tuples of test objects which are then unpacked at the beginning of
every function. This is not unreasonable when multiple objects are

class TestSomething(NumpyTestCase):
    def setUp(self):
        A = array([1,2,3])
        B = array([4,5,6])
        self.d = A, B

    def test_something(self):
        A, B = self.d

It's a little less cumbersome than using self.A and self.B inside each
test case.

Does it make sense to use a length-1 tuple when there's only one piece
of test data, just for consistency?
