using cookbook attribute's inside serverspec testing.

[Prince Paulson]

Hi All,

Has anybody done integration testing with serverspec using cookbook's attributes files integrated.

Thanks,

Yes, what i do is, i render the nodes attributes during the report phase into a json file on disk and load it later on.  For this purpose i wrote a report handler. 

Handler code in a test fixture cookbook  at test/fixtures/cookbooks/helper/files/default/handler/node_attrs.rb

	require 'rubygems' require 'chef/handler'
	module MyHelper
	class NodeAttrs < Chef::Handler
	def report
	attrs = { :ipaddress => @run_status.node.automatic.ipaddress,
	:fqdn => @run_status.node.automatic.fqdn }
	attrs = Chef::Mixin::DeepMerge.deep_merge(attrs, node.default)
	attrs = Chef::Mixin::DeepMerge.deep_merge(attrs, node.normal)
	attrs = Chef::Mixin::DeepMerge.deep_merge(attrs, node.override)
	`mkdir -p /shared`
	File.open('/shared/node.json', 'w') do |f|
	f.write(attrs.to_json)
	end
	end
	end
	End

This handler i register in a recipe at test/fixtures/cookbooks/helper/recipes/node-attrs.rb

	include_recipe 'chef_handler'
	remote_directory node['chef_handler']['handler_path'] do
	source 'handlers'
	mode '0755'
	recursive true
	action :nothing
	end.run_action(:create)
	chef_handler ‘MyHelper::NodeAttrs' do
	source "#{node['chef_handler']['handler_path']}/node_attrs.rb"
	action :nothing
	end.run_action(:enable)

And in the Berksfile:

	group :integration do
	cookbook ‘helper', path: 'test/fixtures/cookbooks/helper'
	End

Then you need a rspec helper beside your tests like this:

	require 'serverspec'
	require 'fileutils'
	require 'json'
	set :backend, :exec
	@chef_node = nil
	RSpec.configure do |c|
	FileUtils.mkdir_p '/shared'
	@chef_node = ::JSON.parse(File.read('/shared/node.json')) unless @chef_node
	end

In the Kitchenfile add “reicpe[helper::node-attrs]” to runlist

In your tests you can use then: 

@chef_node[‘fqdn’] for example.

If you have a private supermarket, you can easily push a cookbook with this code and then reuse it in all your cookbooks.

Cheers Felix
