    context "logged in user" do
      before do
        # Log in user
        @user = FactoryGirl.create(:user)
        session[:user_id] = @user.id
      end

      it "responds with HTTP 201" do

        # Log in user
        @user = FactoryGirl.create(:user)
        session[:user_id] = @user.id
      end

      it "responds with HTTP 201" do
        post :create, achievement: FactoryGirl.attributes_for(:achievement)
        expect(response.status).to eq(201)
      end

      it "creates a new Achievement" do
