### Method
|
|
|
|
|
# The steps below for each file appear convoluted but they are both required
|
|
|
|
|
# and similar in nature:
|
|
|
|
|
# 1. The earliest method was to simply compare the files textually but this often
|
|
|
|
|
# led to false positives due to inconsistencies (e.g. spacing, ordering)
|
|
|
|
|
# 2. The next method was to load the files back into YAML structures and then
|
|
|
|
|
# compare but InSpec provided block diffs this way, unusable by end users
|
|
|
|
|
# 3. The final step was to dump the YAML structures back into a string to use
|
|
|
|
|
# for the comparison; this both worked and provided human-friendly diffs
|
|
|
|
|
|
|
|
|
|
### Comparison file for the specific platform
|
|
|
|
|
### Static, adjusted as part of code contributions, as map data is changed
|
|
|
|
|
# Strip the `platform[:finger]` version number down to the "OS major release"
|
|
|
|
|
platform_finger = system.platform[:finger].split('.').first.to_s
|
|
|
|
|
# Use that to set the path to the file (relative to the InSpec suite directory)
|
|
|
|
|
mapdata_file_path = "_mapdata/#{platform_finger}.yaml"
|
|
|
|
|
# Load the mapdata from profile, into a YAML structure
|
|
|
|
|
# https://docs.chef.io/inspec/profiles/#profile-files
|
|
|
|
|
mapdata_file_yaml = YAML.load(inspec.profile.file(mapdata_file_path))
|
|
|
|
|
# Dump the YAML back into a string for comparison
|
|
|
|
|
mapdata_file_dump = YAML.dump(mapdata_file_yaml)
|
|
|
|
|
|
|
|
|
|
### Output file produced by running the `_mapdata` state
|
|
|
|
|
### Dynamic, generated during Kitchen's `converge` phase
|
|
|
|
|
# Derive the location of the dumped mapdata (differs for Windows)
|
|
|
|
|
output_dir = platform[:family] == 'windows' ? '/temp' : '/tmp'
|
|
|
|
|
# Use that to set the path to the file (absolute path, i.e. within the container)
|
|
|
|
|
output_file_path = "#{output_dir}/salt_mapdata_dump.yaml"
|
|
|
|
|
# Load the output into a YAML structure using InSpec's `yaml` resource
|
|
|
|
|
# https://github.com/inspec/inspec/blob/49b7d10/lib/inspec/resources/yaml.rb#L29
|
|
|
|
|
output_file_yaml = yaml(output_file_path).params
|
|
|
|
|
# Dump the YAML back into a string for comparison
|
|
|
|
|
output_file_dump = YAML.dump(output_file_yaml)
|
|
|
|
|
|
|
|
|
|
describe 'File content' do
|
|
|
|
|
it 'should match profile map data exactly' do
|
|
|
|
|
expect(output_file_dump).to eq(mapdata_file_dump)
|
|
|
|
|
end
