I need to get with @cle to see the best way to create a more permanent testing repo for CentOS-7. When I modify tests/prepare/artifact/providers/repository-file/data/ and tests/prepare/artifact/providers/repository-file/test-bar.repo to point at a package in https://vault.centos.org/7.9.2009/os/x86_64/, I was able to manually verify the fix.

Works when tested manually with RHEL-6 as well.

Isn't there a /tests/prepare/artifact/provider that can be extended to cover this? I think we didn't hit this because the copr one would be incompatible, but if you have an alternative that could be used here, it would be great. Maybe we can use the local file repository? Not a blocker if it becomes too hard to implement.
