You mean the "self!=None" test? Right, that's the same, and it would
fail in unpatched Sage.

Not sure...

That doesn't seem to be very useful.
Or: It could be useful to add the lines
tester.assertEqual(zero, int(0))
tester.assertEqual(zero, 0)
to _test_zero OF RINGS (hence, override the corresponding test method
gotten from commutative additive monoids; or add a new test method
_test_ring_zero). In a similar way, one could compare
self.one_element() with 1 and int(1) for rings.
Of course, here I assume that any ring has a coercion from the ring of
integers (rings in Sage are unital), and should both be able to eat
"0" and "int(0)".
Best regards,
Simon
