simple_approvals/chefspec

a simple chefspec-based implementation of the ApprovalTests pattern

1. Update your Gemfile to include:

   gem 'simple_approvals-chefspec'

2. Update spec_helper.rb to include:

   require 'simple_approvals/chefspec'

3. Add a single template approval like this:

   describe 'my-cookbook::my-recipe' do
     include ChefVault::TestFixtures.rspec_shared_context
     context 'When all attributes are default, on CentOS 7.4.1708' do
       let(:chef_run) do
         # for a complete list of available platforms and versions see:
         # https://github.com/customink/fauxhai/blob/master/PLATFORMS.md
         runner = ChefSpec::ServerRunner.new(platform: 'centos', version: '7.4.1708') do |node, server|
           node.override['my-cookbook']['attribute1'] = true
         end
         runner.converge(described_recipe)
       end
   
   
       it 'converges successfully' do
         expect { chef_run }.to_not raise_error
       end
   
       verify_chef_template(
         expected_path: '/path/to/rendered/template',
         approved_path: 'local/path/to/approved/template/output' # e.g. test/fixtures/approvals/logfile.xml
       )
     end
   end

4. Add multiple template approvals like this:

   describe 'my-cookbook::my-recipe' do
     include ChefVault::TestFixtures.rspec_shared_context
     context 'When all attributes are default, on CentOS 7.4.1708' do
       let(:chef_run) do
         # for a complete list of available platforms and versions see:
         # https://github.com/customink/fauxhai/blob/master/PLATFORMS.md
         runner = ChefSpec::ServerRunner.new(platform: 'centos', version: '7.4.1708') do |node, server|
           node.override['my-cookbook']['attribute1'] = true
         end
         runner.converge(described_recipe)
       end
   
   
       it 'converges successfully' do
         expect { chef_run }.to_not raise_error
       end
   
       verify_chef_templates(
         { expected_path: '/path/to/rendered/template1',
           approved_path: 'local/path/to/approved/template/output1' # e.g. test/fixtures/approvals/logfile1.xml
         },
         { expected_path: '/path/to/rendered/template2',
           approved_path: 'local/path/to/approved/template/output2' # e.g. test/fixtures/approvals/logfile2.xml
         }
       )
     end
   end

1. this library includes a transient dependency on the json gem; since version 2.2.0 this gem requires build_essentials to build native extensions so make sure that is installed somewhere in your environment.

1. make changes
2. bump VERSION
3. gem build simple_approvals-chefspec.gemspec
4. gem push simple_approvals-chefspec-1.0.0.gem
