RSpec Helper for Validating Token-based Auth Headers Returned with Request

respec_helper_bearer_token_session_headers.rb

module RequestSpecHelper::SessionsHelper

  # Set single expectation that checks auth headers were returned.
  def expect_auth_headers(response)
    expect(response.headers.keys).to include('access-token', 'client', 'expiry', 'uid')
  end

end

# Include this file in each "Sessions" Request spec, at the top of the file:

include RequestSpecHelper::SessionsHelper

# Or, alternatively, include it in every Request spec, in the `rails_helper.rb` config file:

config.include RequestSpecHelper::SessionsHelper, type: :request

Use this helper along with :request specs, when bearer tokens are used for authentication. Works well with the devise_token_auth gem.
