So, as mentioned, the let(:title) method is actually just for defined
types:
http://rspec-puppet.com/tutorial/#specifying_the_title_of_the_defined_type
Given you have a class, title could be coming from a fact, in which
case you could use use:
let(:facts) { {:title => 'foo'} }
Or it should be a parameterised class, in which case use:
let(:params) { {:title => 'foo'} }
(given the special nature of title these may not work, but demonstrate
how to pass values to different constructs)
Or as mentioned it should be a defined type, in which case use let(:title).
I'd probably recommend trying to write a test for one of your
real-world puppet modules as I think the issue is with the Puppet code
more than the tests.
For a bit more context around the difference between name and title
see the docs too:
https://docs.puppetlabs.com/puppet/latest/reference/lang_defined_types.html#title-and-name
