Hi all,
I am writing a custom hiera backend for consul and I want to test the
functionality.
But I am unable to create the proper puppet data structures that are
required by the function definition.
Part of the function I want to test:
Puppet::Functions.create_function(:hiera_consul) do
dispatch :lookup_key do
param 'Variant[String, Numeric]', :key
param 'Hash', :options
param 'Puppet::LookupContext', :context
end
def lookup_key(key, options, context)
if confine_keys = options['confine_to_keys']
raise ArgumentError, 'confine_to_keys must be an array' unless confine_keys.
is_a?(Array)
confine_keys.map! { |r| Regexp.new(r) }
regex_key_match = Regexp.union(confine_keys)
unless key[regex_key_match] == key
context.explain { "Skipping consul backend because key does not match
confine_to_keys" }
context.not_found
end
end
....
end
end
The test:
describe 'hiera_consul' do
it "is confined to certain keys" do
context = Puppet::Pops::Lookup::Context.new({},{})
is_expected.to run.with_params('test_key', {'k' => 'v'}, context)
end
end
The results:
1) hiera_consul is confined to certain keys
Failure/Error: is_expected.to run.with_params('test_key', {'k' => 'v'},
context)
expected hiera_consul("test_key", {"k"=>"v"},
#<Puppet::Pops::Lookup::Context:0x007fdb7acc7060
@lookup_invocation={}, @function_context={}>) to have run successfully
instead of NoMethodError(undefined method `gsub!' for nil:NilClass)
What would the right way to construct the arguments for this signature?
Specifically
- how do i create Puppet::LookupContext. Is this really the way?
- how do i create a puppet hash construct with data in it?
With regards,
Jos Houtman
