Motivation

The on_supported_os method provided by rspec-puppet-facts provides facts captured from running Vagrant systems. However, many SIMP tests require additional custom facts.

This gem acts as a shim in front of mcanevet/rspec-puppet-facts and can be used as a drop-in replacement when testing for SIMP. It uses a combination of Vagrant-captured SIMP facts and logic to model certain environments (e.g., SELinux modes, LSB facts being present or not).

Usage

Basic usage

Use this code inside spec_helper.rb:

require 'simp/rspec-puppet-facts'
include Simp::RspecPuppetFacts

Use this structure inside your *_spec.rb files:

require 'spec_helper'

describe 'module_name::class_name' do
  # loops through and provides facts for each supported os in metadata.json
  on_supported_os.each do |os, base_facts|
    context "on #{os}" do
      let(:facts){ base_facts.dup }
      it { is_expected.to compile.with_all_deps }
    end
  end
end

Providing options

See the options for details

  on_supported_os({:extra_facts=>{:username=>'flastname'}})
  on_supported_os({:selinux_mode=>:permissive})

Options

:extra_facts

[default: {}]

Override or add extra facts to each os/facts hash.

NOTE: Facts managed by internal logic (such as :selinux, :selinux_current_mode, :tmp_mount_*, etc) will still be overwritten. To avoid this, use :extra_facts_immutable instead.

:extra_facts_immutable

[default: {}]

Override or add extra facts to each os/facts hash. These facts cannot be altered by internal logic (such as :selinux_mode).

:selinux_mode

[default: :enforcing]

Given an enforcement mode (:enforcing, :permissive, or :disabled), overrides the following facts:

• selinux
• selinux_enforced
• selinux_current_mode
• selinux_state
• tmp_mount_* (only modifies existing tmp_mount* facts)

Example: Default SELinux mode (:enforcing)

# Default facts (`.first.last` returns facts for the first os)
facts_hash = on_supported_os.first.last
facts_hash.values_at(:selinux,:selinux_current_mode,:selinux_state,:tmp_mount_dev_shm)
### => [true, "enforcing", "enforcing", "rw,relatime,seclabel"]

Example: Setting facts to model when SELinux is disabled

# Set selinux mode to `disabled`
facts_hash = on_supported_os({:selinux_mode => :disabled}).first.last
facts_hash.values_at(:selinux,:selinux_current_mode,:selinux_state,:tmp_mount_dev_shm)
### => [false, "disabled", "disabled", "rw,relatime"]

Environment Variables

FACTER_GEM_VERSION

Set to install a specific version of facter. Only works on systems where puppet can be installed natively via gem.

BEAKER_facter_ng

Set to yes to switch over to using facter-ng (Facter 4) for collection.

Requires using beaker to collect facts.

SIMP_FACTS_OS

Restricts test matrix to OS strings/partial strings/regexps provided in a comma-delimited list.

• Example: SIMP_FACTS_OS=redhat-7-x86_64,centos

SIMP_FACTS_lsb

Mock the output of historical lsb facts

• Disable by setting to no

How to capture new facts

Beaker (preferred)

• Add nodesets to spec/acceptance/nodesets
• Run bundle exec rake beaker:suites[default,ALL]
  • Replace ALL with the name of a specific nodeset if you only want to collect on a single OS.
• Review the facts in the collected_facts directory.
• Update the facts in the associated facts directory.
  • Make sure to rename the file as <lowercase_os>-<major_version>-<arch>

Vagrant

• Place any modules containing facts you want to capture under modules/
• Run vagrant up NOTE: This replaces any older fact data
