ruby-on-rails – 使用Rspec和Rack :: Test測試REST-API響應

我有點悶了我有以下整合測試：

require "spec_helper"

describe "/foods", :type => :api do
include Rack::Test::Methods

let(:current_user) { create_user! }
let(:host) { "http://www.example.com" }

before do
login(current_user)
@food = FactoryGirl.create_list(:food, 10, :user => current_user)
end

context "viewing all foods owned by user" do

it "as JSON" do
get "/foods", :format => :json

foods_json = current_user.foods.to_json
last_response.body.should eql(foods_json)
last_response.status.should eql(200)

foods = JSON.parse(response.body)

foods.any? do |f|
f["food"]["user_id"] == current_user.id
end.should be_true

foods.any? do |f|
f["food"]["user_id"] != current_user.id
end.should be_false
end

end

context "creating a food item" do

it "returns successful JSON" do
food_item = FactoryGirl.create(:food, :user => current_user)

post "/foods.json", :food => food_item

food = current_user.foods.find_by_id(food_item["id"])
route = "#{host}/foods/#{food.id}"

last_response.status.should eql(201)
last_response.headers["Location"].should eql(route)
last_response.body.should eql(food.to_json)
end

end

end

我已經添加了所需的Rack :: Test :: Methods來獲取last_response方法,但它似乎沒有正常工作. last_response總是似乎告訴我sign_in頁面,即使我已經登入.

如果我刪除Rack :: Test ::方法last_response消失,我可以使用響應,我得到當前的響應.一切似乎都行.

為什麼是這樣？響應方法來自哪裡？可以使用響應來獲取會話的上一個響應嗎？

我需要使用last_response或類似的東西

last_response.headers["Location"].should eql(route)

所以我可以匹配路線.如果不是這樣,我將被設定.

響應對於某些規格型別是自動的.

Rspec可能會混合ActionController :: TestCase :: Behavior for：type => ：api塊.

響應將來自ActionController :: TestCase :: Behavior,如下所示：type => ：控制器塊.

如果要在響應之前獲得響應,請嘗試將其儲存在變數中,然後再進行下一個請求.
