Example of testing an individual element of an array from a parameter of a resource in rspec-puppet

hosttest_spec.rb

require 'spec_helper'

describe 'hosttest' do
  context 'with default values for all parameters' do
    context 'With foo.local host pre_condition' do
      let(:pre_condition) {"
        host { 'foo.local':
          ip => '1.2.3.4',
          host_aliases => [ 'foo1.local', 'foo2.local' ],
        }
      "}
      # This style works, but it requires the exact and full array for comparison
      it { should contain_host('foo.local').with_host_aliases( ['foo1.local', 'foo2.local'] ) }
      # This works, but it feels really awkard to do
      it {
        host_aliases = catalogue.resource('host', 'foo.local').send(:parameters)[:host_aliases]
        expect(host_aliases).to include('foo1.local')
      }
    end
  end
