True. > And if it is encountered and fixed, such errors should not happen again. False. Such errors *will* happen again -- they are called regressions. In order to avoid those we add tests, and those tests serve several purposes: - confirm the problem has been fixed (not every bug is a core-dump) - confirm that changes in the future don't reintroduce the bug - communicate past difficulties and possible gotchas to new developers In short: add tests; patches are not complete without them. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27512> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
