rspec_api_documentation - как иметь несколько примеров

Question

Моя цель - показать несколько примеров параметров и ответов, используя rspec_api_documentation с rswag-ui или добавляя swagger-ui непосредственно в проект. У меня возникли проблемы с генерацией правильного open_api. json с моей конфигурацией, и мне интересно, что я делаю неправильно.

Gems:

• https://github.com/zipmark/rspec_api_documentation
• https://github.com/rswag/rswag

rspec_api_documentation config для тестов:

# spec/acceptance_helper.rb
require 'spec_helper'
require 'rspec_api_documentation'
require 'rspec_api_documentation/dsl'

RspecApiDocumentation.configure do |config|
  config.app = Rails.application

  config.api_name = 'My API'
  config.api_explanation = 'API Description'

  config.configurations_dir = Rails.root.join('public', 'docs', 'api', 'config')
  config.docs_dir = Rails.root.join('public', 'docs', 'api', 'generated')

  config.format = :open_api

  API_VERSIONS.each do |version|
    config.define_group(version) do |config|
      config.docs_dir = Rails.root.join('public', 'docs', 'api', 'generated', version.to_s)
    end
  end

  config.client_method = :client

  config.io_docs_protocol = 'https'

  config.request_headers_to_include = nil
  config.request_body_formatter = :json

  config.response_headers_to_include = []
  config.response_body_formatter = Proc.new { |response_content_type, response_body|
    response_body
  }
end

OpenAPI config:

Примеры тестов:

  explanation 'Endpoints to start and end API sessions for a user'

  route '/api/v1/users/sign_in', 'Sign In' do
    route_summary 'Starts a new session for a user'
    route_description 'Given valid credentials, will create a new API session for a user'

    post 'Signing in a user', document: :v1  do
      let(:user) { FactoryBot.create(:user) }

      parameter :login, 'The username or email of the user', scope: :user, required: true
      parameter :password, 'The password for the user', scope: :user, required: true

      example '401 - No user object', document: :v1 do
        request = { login: user.email, password: user.password }

        do_request(request)

        expect(status).to eq(401)
        expect(json.keys.size).to eq(1)
        expect(json['error']).to eq(I18n.t('devise.failure.unauthenticated'))
      end

      example '401 - No login', document: :v1 do
        request = { user: { password: user.password } }

        do_request(request)

        expect(status).to eq(401)
        expect(json.keys.size).to eq(1)
        expect(json['error']).to eq(I18n.t('devise.failure.unauthenticated'))
      end
    end
  end
end
