Friends, As an extension of my work on https://rt.perl.org/rt3/Ticket/Display.html?id=112126, I am trying to measure the test coverage for Perl 5 core distribution Hash-Util provided by the Perl 5 test suite. For ease of development, I have copied ext/Hash-Util/lib/Hash/Util.pm and ext/Hash-Util/t/Util.t into a typical CPAN distribution setup. I have applied the patches submitted in RT #112126 and modified t/Util.t to remove all the setup needed to run it as part of the Perl 5 test suite and instead run it as if it were a part of a regular CPAN distribution. So I'm now at a point where I want to perform coverage analysis. However, try as I might, I cannot get a report of the test coverage of lib/Hash/Util.pm I want -- and this having used Devel::Cover for nine years! Please see the attachment in which I show the output of: perl Makefile.PL && make && cover -test Note that I *am* getting coverage output for Util.xs, but I'm *not* getting coverage for lib/Hash/Util.pm. This is most puzzling. I have Devel::Cover version 0.80 installed and am running this with Perl 5.14.2. To facilitate getting assistance with this, I have push my quasi-distribution to Github: https://github.com/jkeenan/Hash-Util Can anyone advise as to why I am getting coverage analysis of Util.xs but not of lib/Hash/Util.pm? Thank you very much. Jim Keenan
