Sorry for bringing up an old thread, but I hit the same issue and found
a workaround.
rspec-puppet calls #inspect on the parameter values to see how they
should be represented in Puppet's DSL, so passing a string in causes it
to get quoted (as String#inspect returns a quoted string).
Instead, I created a small class that returns an unquoted value.
in spec_helper.rb:
class Undef
def inspect
'undef'
end
end
and then to use it:
let(:params) do
{ :example => Undef.new }
end
