--- Comment #6 from Mike Stump <mikestump at comcast dot net> 2012-04-18 22:42:55 UTC --- So, do you have a pointer to where a maintainer said that they require 3 duplicates for a piece of work? For all similar future work? They usually say, please include a testcase, meaning, one testcase. One is certainly reasonable. For some work, for some cases, they might want 2 or 3 testcases, but, those I suspect should be rare to very rare. The requirements for 3 for that change should not be read as to be generally require 3 for all future changes... or, at least, that'd be my interpretation.
