Hi all, I'm offering a (free) service to CPAN module authors who may be wanting more (or more rapid) CPAN Testers test reporting on CPAN modules installed on Mac OS X.
I've become frustrated with that myself, so I installed all 43 versions of Perl through 5.27.4, using Perlbrew of course, and now I can install, test, and file test results report on a module for all versions with:
$ perlbrew exec -- 'cpanm -q Foo::Bar && cpanm-reporter'
Of course you can do this yourself on any OS (and you should). I'm only testing on the Mac OS X version I have installed (10.11.6 "Yosemite"), and Mac testing platforms are sadly lacking, so if you are running an older OS X please consider setting up at least the most recent stable subversion of the last few major versions and helping out. It's a pretty cool feeling watching the test reports go out.
And if you are working on a module and want to get Mac OS X test reports into the CPAN Testers matrix quickly, send me a private message here and I'll run the tests on it. Be sure it's going to pass though, as the results are sent in either way!
Update, corrected name of the CPAN service, thanks hippo.
