我有点困惑。我有以下集成测试:
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
我已经添加了所需的rack::test::方法来获取
last_response
方法,但它似乎不起作用。last_response
尽管我已经登录,但似乎总是显示我登录页面。如果删除rack::test::methods
last_response
时,我可以使用response
来代替它,并得到当前响应。一切似乎都正常。这是为什么?
response
方法从何而来?我可以使用response
从会话中获取先前的响应吗?我需要使用
last_response
或类似的东西last_response.headers["Location"].should eql(route)
这样我就能匹配路线。如果不是因为这个,我就完了。
最佳答案
response
对于某些规范类型是自动的。
rspec可能为ActionController::TestCase::Behavior
块混合:type => :api
。response
将来自于ActionController::TestCase::Behavior
,就像对于:type => :controller
块一样。
如果要在response
给出的响应之前获取响应,请在发出下一个请求之前尝试将其存储在变量中。
