Michael Foord <mich...@voidspace.org.uk> added the comment: assertEqual uses Python equality semantics - so if a str instance and a unicode instance compare equal then assertEqual passes. This is by design.
The type check in assertEqual, that delegates to the different comparison methods, is strict because we can't know that using the error message algorithms is sane for arbitrary subclasses - all we can know is whether an equality comparison fails or succeeds. Using a diff algorithm for creating an error message only makes sense for text, which is why it is only done for unicode. For binary strings a diff is more likely to be unintelligible nonsense. For comparing unicode to strings you can call asssertMultilineEqual directly. ---------- resolution: -> invalid status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14025> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
