Rspec Puppet: Defined Type iteration - puppet

Question

Iterating over an array of hashes using a Defined Type
Getting an Error, telling me that my parameter (which defaults to the value of $title) cannot be accessed the way I am because it is not an Array or Hash
I'm using old-style iteration in a puppet module, creating a defined type to iterate over an array of hashes. I'm trying to write a test for this define in rspec-puppet, attempting to assign a hash to the :title using let(). The $title is then supposed to be set to my variable called $daemon, yet my tests keep throwing errors saying that $daemon is not a hash or array.
Here's how I'm creating my defined type:
define my_module::daemon_install ($daemon = $title) {
package {"${daemon['package_name']}":
ensure => "${daemon['package_version']}",
}
file {"${some_fact}/${daemon['binary']}.conf":
ensure => file,
content => "blah"
notify => Service["${daemon['name']}"],
}
service {"${daemon['name']}":
ensure => running,
enable => true,
}
}
And here's how I'm trying to set the title:
describe 'my_module::daemon_install' do
context 'with foo' do
let(:title) {
{
"name" => "foo",
"package_name" => "bar",
"package_version" => "1.0.1",
"binary" => "food",
}
}
# ...
end
end
And here's the error:
daemon is not a hash or array when accessing it with package_version
I'm actually abit new to using defined types for iteration, and very new at rspec-puppet, so I'm not sure if I'm missing something obvious here or not.
But why is it only complaining about package_version and not package_name? And more importantly: why is it not a hash, when (I believe) I'm setting it to a hash correctly in the spec file.
I should mention that another test, of a class which uses this defined type, completes successfully. So it seems related to how I'm trying to set the title when directly testing the define, if I were to guess.

Answer 1

Rspec always converts title into String.
Use $name in define() instead of $title and add the following into tests:
let :title do
{ ... }
end
let :params do
{ :name => title }
end
Please note$name should be equal of $title.
