Post リソースを使用して scaffold アプリケーションを生成しました。

ここにテストコードがあります

  describe "GET index" do
    it "assigns all posts as @posts" do
      post = Post.create! valid_attributes
      get :index, {}, valid_session
      assigns(:posts).should eq([post])
    end
  end

これが実装ですposts#index

  # GET /posts
  # GET /posts.json
  def index
    @posts = Post.all
  end

正当に思えますが、rspec を実行しているときにこのエラーが発生し続けます。ヒントを教えていただければ本当にうれしいです。

テストが失敗する理由は 2 つあります。まず、あなたはから戻ってくるのActiveRecord::Relationではなく、得ています。第 2 に、このテストが実行されるまでに 22 件の投稿が既に作成されているようです。Arrayassigns(:posts)

最初の違いは Rails 4 の変更によるもので、 http://edgeguides.rubyonrails.org/4_0_release_notes.htmlで説明されているように、ではなくModel.allを返すようになりました。ActiveRecord::RelationArray

既存の投稿がある理由を説明できません。タイムスタンプに基づいて、このテストの直前に作成されたようです。これより前に、他の作成後のテストが実行されますか? 取引を停止していませんか？
