Puppet users - Jun 2013 - Is it possible to pass extra flags to Puppet via rspec?`

Hello,

I''m writing my first puppet function rspec test and am having a problem
which I don''t see how to solve.

The function (and the test) involve access to files through the File 
Server. In order for the function (and the test) to work I need to pass 
"--fileserverconf=fileserver.conf" parameter to Puppet.

So far I haven''t found a way to do that.

If I understand the rspec-puppet source 
at https://github.com/rodjek/rspec-puppet/blob/master/lib/rspec-puppet.rb 
correctly then the list of parameters I can pass is limited to the ones 
mentioned in lines 16-22. Am I right?

Does anyone know how can I pass other parameters, or otherwise affect 
Puppet''s configuration to set this value?

Thanks,

--Amos

Hi Amos,

Here''s what I''ve done:

in spec/spec_helper.rb:

Puppet.settings[:confdir] = "spec/fixtures"

then in the class I was working on, I made a parameter:


class foo(
  $puppetdir = $settings::confdir
  ){
…
}


then in that class''s spec test:

require ''spec_helper''
require ''puppetlabs_spec_helper/module_spec_helper''
foo = Puppet.settings[:confdir]

describe ''foo'', :type => :class do

let (:params) do { ''puppetdir'' => foo } end


…


it stands to reason that a similar method could be employed to feed your
function, but I''m not certain.

Oddly enough, you can''t depend on rspec-puppet to configure the
settings
for spec test. For example, puppetlab''s spec helper configures the
modulepath [1] to include spec/fixtures/modules, but this does not seem to
configure Puppet[:modulepath] setting. For whatever reason, puppet loads
the modules correctly from spec/fixtures/modules, but when you debug the
spec test, it appears to set the module path to:

(rdb:1) p Puppet[:modulepath]
"/dev/null/modules:/usr/share/puppet/modules"

You can do what Wolf suggested. File server conf is somewhat inconsistent,
since the setting is actually: Puppet[:fileserverconfig].

HTH,

It''s been a while since I jumped into this code and it''s late,
forgive me
if I say something naive inline.

Those are the limit you can pass to the RSpec.configure { ... } block in
your spec helper.

Nan -

In puppetlabs_spec_helper/puppet_spec_helper[1] which was based on a file
in Puppet[2] the confdir and vardir are explicitly set to
''/dev/null'' which
causes the modulepath you''re seeing in Puppet "proper".

I believe, however the subject catalog/function that is tested in each
example group (unless you explicitly create a subject yourself) should mask
that value with what ever is passed into RSpec.configure (like the
modulepath setting in module_spec_helper) for its
compilation/initialization[3][4].

Thanks for the clarification, that would certainly explain why I''m
seeing
/dev/null in module path.

Thanks for the tip, Justin and everyone else who replied.
I''ll try your suggestion.
