Assuming that you run Fedora, you can patch the current specfile that is
in rawhide with the patch in [1]. Then, just execute "fedpkg
mockbuild". I tried to manually make the test fail directly inside the
mock buildroot, but couldn't make it work.  After patching the spec, you
can create an srpm with "fedpkg srpm" and then use mock direcly like so:

$ mock -r fedora-rawhide-x86_64 --no-cleanup --no-cleanup-after <path to srpm>

You'll then have the root and the results in /var/lib/mock/fedora-rawhide-x86_64/result.
