### Test parameters of symlinked file
If you need to test the parameters of the target file for a symlink, you can use the `link_path` method for the `file` resource.
For example, for the following symlink:
lrwxrwxrwx. 1 root root 11 03-10 17:56 /dev/virtio-ports/com.redhat.rhevm.vdsm -> ../vport2p1
... you can write controls for both the link and the target.
describe file('/dev/virtio-ports/com.redhat.rhevm.vdsm') do
it { should be_symlink }
end
virito_port_vdsm = file('/dev/virtio-ports/com.redhat.rhevm.vdsm').link_path
describe file(virito_port_vdsm) do
it { should exist }
it { should be_character_device }
it { should be_owned_by 'ovirtagent' }
it { should be_grouped_into 'ovirtagent' }
end
