rspecでruby on rails3(devise)のcontrollerをいい感じに書いてみた～part2

前回の投稿の続きであるが、
さらに、GETアクションに加え、CREATE・UPDATEアクションも考慮して汎用ロジックを組んでみました。

前回のエントリも参考にしていだだきたい。
[　rspecでruby on rails3(devise)のcontrollerをいい感じに書いてみた～part1　]

【環境】
devise'2.0.4'
rails'3.1.3'
rspec-rails'2.8.0'

【テスト概要】

アクションごとに

ログインしている場合
・取得オブジェクトが参照できる

：renderingを期待している場合
　 ・responseが200[OK]である
 　・正しいtemplateをレンダーする
：redrectを期待している場合
   ・正しいリダイレクト先へいく

ログインしてない場合
   ・取得オブジェクトが参照できない
   ・正しいリダイレクト先へいく

をテストすることを想定。

BlogsControllerのクリエイトとアップデートアクションです

 # POST /blogs
  # POST /blogs.json


  def create
    @blog = Blog.create(current_user,params[:blog])
    @result = @blog.save

    respond_to do |format|
      if @result
        format.html { redirect_to @blog, notice: 'Blog was successfully updated' }
        format.json { render json: @blog, status: :created, location: @blog }
      else
        format.html { render action: "new" }
        format.json { render json: @blog.errors, status: :unprocessable_entity }
      end
    end
  end

  # PUT /blogs/1
  # PUT /blogs/1.json
  def update
    @blog = Blog.find(params[:id])
    @result = @blog.update_attributes(params[:blog])

    respond_to do |format|
      if @result
        format.html { redirect_to @blog, notice: 'Blog was successfully updated.' }
        format.json { head :ok }
      else
        format.html { render action: "edit" }
        format.json { render json: @blog.errors, status: :unprocessable_entity }
      end
