New submission from Phlip <phlip2...@gmail.com>: The various assertions are not DRY when they force you to repeat any automatic diagnostic in a message string, if you provide it.
Here's an example: def assertEqual(self, first, second, msg=None): self.assert_((first == second), msg or '%s != %s' % (first, second)) I think it should work like this: def assertEqual(self, first, second, msg=''): self.assert_((first == second), (msg + ('\n%s != %s' % (first, second))).strip()) That way, if you provide a message (such as a message describing the semantic _meaning_ why "41" should not equal "42"), the assertion does not throw away the automatically generated "41 != 42". In the current system, to correctly reflect the 41 and 42, you must add them to the msg body. This is redundant with the assertions' primary behaviors... ---------- components: Tests messages: 97833 nosy: Phlip severity: normal status: open title: the msg parameters of PyUnit assertions, such as assertEqual, should not obscure the automated diagnostics, such as '%s != %s' type: feature request versions: Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7709> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
