NORMALIZE_WHITESPACE converts your pattern into Generated script '/sample-buildout/bin/bo'. ... SyntaxError:... and the matched text to Generated script '/sample-buildout/bin/bo'. SyntaxError:... Then ELLIPSIS has a mismatch because even if you substitute the '...' with an empty string, the pattern wants two spaces where the text has one. I tried to report this as https://bugs.launchpad.net/zope.testing/+bug/126169 once, but was unable to convince Jim that this behaviour trips people up. (Also, I did not try to provide a patch to fix the issue.) HTH, Marius Gedminas -- This sentence contradicts itself -- no actually it doesn't. -- Douglas Hofstadter
