In this type of situation I will often write a unit test that makes
sure that the piece of information I just added to the message is really
in the message ('%o', in this case), using assertRaisesRegex. I don't
think it is required, but I like to do it, because it would indeed be
a regression if that information stopped appearing in the message.
