So let me try this again. Here is the full init.pp and spec file being 
used.  The setup is very simple.  Likewise it does't matter if the 
*$sshd_hostkey_rhel_cent_7 
*is setup as a smart parameter or set inside the module itself, the error 
"*Evaluation 
Error: Error while evaluating a Function Call, no implicit conversion of 
Hash into String at line 2:1 on node*" persists relative to where the array 
is defined. 

*Note: I attached the templates/sshd_config.erb* *for brevity.*

I find this quite perplexing as the array is defined properly and when I 
run t on a CentOS 7 / RHEL 7 box, via puppet apply, I have no errors. This 
happens on my dev Foreman/Puppet 4 server and on a stand-along VM spun up 
just to verify this behavior persists on a clean install of the puppet 
agent and gems to do spec testing. (*Output of puppet apply the end of the 
post)*

----------------------------------------------
So if in manifests/init.pp I comment out lines 18-26 and 44:

class ssh::sshd_config (
  # Hostkey setting for CentOS / RHEL 7
*#  $sshd_hostkey_rhel_cent_7 = [*

  include ssh

...
        # CentOS / RedHat 7 +

Then run *rake spec* I get:

If I run the original init.pp above, i get the following when I run *rake
