New submission from R. David Murray <rdmur...@bitdance.com>: Just as with regular strings, when comparing failed output involving bytes strings it is really helpful to have a diff showing which bytes have changed. The attached patch adds an assertMultiLineEqual method to unittest and uses it for comparing bytes in assertEqual.
The diff output is created by first breaking the byte strings into lines using 'splitlines(True)' just as in assertMultiLineEqual, but then each line is converted to a string using 'repr' before the lines sets are passed to ndiff. This results in output containing escaped bytes, making it easier to compare the differences in the byte strings. (NB: this patch is the end result of several attempts to make the unittest output more useful in the email package when testing bytes handling). ---------- files: bytes_multi_line_equal.diff keywords: patch messages: 119280 nosy: michael.foord, r.david.murray priority: normal severity: normal stage: patch review status: open title: Add an assertBytesMultiLineEqual to unittest and use it for bytes assertEqual type: feature request versions: Python 3.2 Added file: http://bugs.python.org/file19320/bytes_multi_line_equal.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10164> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
