ruby-on-rails - sunspot_railsを使用してアプリをテストするためのRSpec仕様の記述

Question

sunspot_matchers gem（または単なるRSpec）でRSpecを使用して、sunspot gemを使用してコードをテストする良い例はありますか？

このエラーで何が起こっているのかを理解しようとしていますが、確かな例は見つかりません。

これが私が現在取り組んでいるモデル、スペック、スペック出力からのスニペットです：

/models/channel.rb

class Channel < ActiveRecord::Base

  #...some attributes and methods here

  private

  # selected_facets is a hash with strings as keys
  # facet_categories is an array of symbols
  def self.search_results(search_query, selected_facets, facet_categories)
    Channel.search do
      keywords(search_query)
      facet_filter = selected_facets

      dynamic :facets do
        facet_categories.each do |category_name|
          if selected_facets.nil? or selected_facets[category_name.to_s].nil?
            facet(category_name)
          else
            with(category_name, selected_facets[category_name.to_s])
          end
        end
      end

    end
  end
end

/spec/models/channel_spec.rb

describe ".search_results" do
  let(:facet_categories) { [:category1, :category2, :category3] }
  let(:query) { "just a test query" }

  it "should search for Channels" do
   selected_facets = ""
   Channel.search_results(query, selected_facets, facet_categories)
   Sunspot.session.should be_a_search_for(Channel)
  end

  context "when there are no selected facets" do
    let(:selected_facets) { nil }
    it "it facets on that category name" do
      channels = Channel.search_results(query, selected_facets, facet_categories)
      Sunspot.session.should have_search_params(:facet, :category1)
    end
  end

  context "when there are no selected facets for the given category name" do
    it "it facets on the given category name"
  end
end

上記のモデルでif/else条件をテストしようとしています。

何か案は？または、全体的なアプローチに関するアドバイスはありますか？

いくつかの良い例/ドキュメントは素晴らしいでしょう...または多分私はどこかで何かを逃しただけです。

ありがとう、
