openSUSE:Leap:15.2 openSUSE Leap 15.2 openSUSE Leap borrows packages from SLE for the base system. Please refer to https://osrt.opensuse.org/web/origin-manager/#openSUSE:Leap:15.2 for origin information https://download.opensuse.org/distribution/leap/15.2/repo/oss/ perl-Test-UseAllModules do use_ok() for all the MANIFESTed modules I'm sick of writing 00_load.t (or something like that) that'll do use_ok() for every module I write. I'm sicker of updating 00_load.t when I add another file to the distro. This module reads MANIFEST to find modules to be tested and does use_ok() for each of them. Now all you have to do is update MANIFEST. You don't have to modify the test any more (hopefully).
