Searchef

Stub your Chef searches with pre-canned responses. Good for use when unit testing or dummying out a Chef run that uses search calls.

Installation

Add this line to your application's Gemfile:

gem 'searchef'

And then execute:

$ bundle

Or install it yourself as:

$ gem install searchef

Usage

Setup

Require the library and include the Searchef::API module for convenience:

require 'searchef'

include Searchef::API

Stubbing Node Searches

# stub search for all nodes with the `web_node` role in their run list
stub_search(:node, "roles:web_node").to_return([
  node_stub("web1.example.com"),
  node_stub("web2.example.com")
])

require 'chef/search/query'

# if running in pry, let's set a node name for signing requests
Chef::Config[:node_name] = "durr"

# run the search
query = Chef::Search::Query.new
query.search(:node, "roles:web_node")

# => [[node[web1.example.com], node[web2.example.com]], 0, 2]

You can also stub more complicated nodes with specific data:

# setting a node platform and platform verson
node_stub("node1.example.com", :platform => "centos", :version => "6.3")

# overriding default fauxhai ohai data
node_stub("node2.example.com", :ohai => { :ipaddress => "19.2.168.10.1" })

# set node attribute data, such as the run_list
node_stub("node2.example.com", :attrs => {
  :run_list => [ 'recipe[common::base]', 'role[load_balancer]' ]
})

# using a block which provides access to the attributes file dsl methods
node_stub("node3.example.com", :ohai => { :ipaddress => "10.10.12.27" }) do
  default['mysql']['tunable']['tmp_table_size'] = "64M"
end

Stubbing Data Bag Searches

Data bags are a hash of data, so you can return data bag items as an array of hashes:

stub_search(:users, 'groups:admin').to_return([
  {
    "id" => "adam",
    "comment" => "Adam Administrator",
    "groups" => [
      "admin"
    ],
    "ssh_keys" => [],
    "shell" => "/bin/bash"
  }
])

If your data_bag_path is setup, you could also fectch the data from a real data bag, using the data_bag_item method:

stub_search(:users, 'groups:admin').to_return([
  data_bag_item("users", "adam")
])
