The package needed would be perl-module-runtime (was missing last hyphen). https://www.archlinux.org/packages/community/any/perl-module-runtime/ The error is complaining about not being able to find Module/Runtime.pm in @INC.

There is no package named "perl-module", neither in Arch itself nor in the AUR. So what exactly are you referring to? And how do the tests fail if you don't have that thingy installed (actual error messages, please)?

In order for the tests to succeed it seems like it needs to have perl-module runtime in makedepends.

Rebuild and install perl-sub-name.
