request spec のテンプレート作成

kurasus_controller.rb に対して，一通りの request spec が作成できたので，これをベースに template を作成する．

  1. kurasus_spec.rb を lib/templates/rspec/integration/request_spec.rb にコピーする．
    2. cp spec/requests/kurasus_spec.rb lib/templates/rspec/integration/request_spec.rb
  2. クラス名などを erb を使って書き換える．最終的に生成した request_spec.rb を掲載しておく．とりあえず現状のもので今後修正する可能性はある．
    3. require 'rails_helper'

request spec のまとめ

request spec は以前の controller spec の代わりになるものである． controller spec と違って内部のオブジェクトまではテストせず，あくまでリクエストの成功などを確認するだけに限定された． このため，controller spec よりもテストがやりやすくなったと思う． 以下に今回の kurasus_spec.rb のテスト結果をまとめて示しておく．
