Rspec::Raml

RSpec matchers for working with RAML.

Add this line to your application's Gemfile:

gem 'rspec-raml'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rspec-raml

First, you'll need to include RSpec::Raml's helpers in your RSpec configuration.

RSpec.configure do |config|
  config.include RSpec::Raml::Matchers, type: :request
end

Assume you've got a RAML specification:

#%RAML 0.8
---
title: Dummy API
baseUri: https://dummy-api.com/api/{version}
version: v1

/users:
  /{id}:
    displayName: Find a user
    get:
      responses:
        200:
          description: User was found.
          body:
            application/json:
              example: |-
                {
                  "id": 1,
                  "first_name": "John",
                  "last_name": "Doe"
                }

You can write a spec that compares an HTTP response with the RAML specifcation you've written.

# spec/requests/api/v1/users_spec.rb

describe 'Users API' do
  describe 'GET /api/v1/users/:id' do
    raml { Rails.root.join('docs/api/v1.raml') }

    let(:user) {
      User.create!(
        id: 1,
        first_name: 'John',
        last_name: 'Doe'
      )
    }

    it 'is documented' do
      get "/api/v1/users/#{user.id}"
      expect(response).to match_raml(:get, '/users/{id}', 200)
    end
  end
end

The match_raml matcher will verify that the status code returns successfully, and that the response body matches what you've declared in your RAML specification.

If you haven't written your specification yet, RSpec::Raml will output an example RAML specification.
