使用 Rspec 和 Rack::Test 测试 REST-API 响应 [英] Testing REST-API responses with Rspec and Rack::Test
问题描述
我有点不知所措.我有以下集成测试:
I am a bit stumped. I have the following integration test:
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
我添加了所需的 Rack::Test::Methods 来获取 last_response
方法,但它似乎无法正常工作.last_response
似乎总是向我显示登录页面,即使我已经登录.
I've added the required Rack::Test::Methods to get me the last_response
method but it doesn't seem to work right. last_response
always seems to show me sign_in page even though I've already signed in.
如果我删除 Rack::Test::Methods last_response
消失,我可以使用 response
代替,我得到当前响应.一切似乎都正常.
If I remove Rack::Test::Methods last_response
goes away and I can use response
instead and I get the current response. Everything seems to works ok.
这是为什么?response
方法从何而来?我可以使用 response
从会话中获取上一个响应吗?
Why is this? Where is the response
method coming from? Can I use response
to get the previous response from the session?
我需要为
last_response.headers["Location"].should eql(route)
以便我可以匹配路线.如果不是因为这个,我会准备好.
so that I can match the routes. If it weren't for this I would be set.
推荐答案
response
对于某些规范类型是自动的.
response
is automatic for certain spec types.
Rspec 可能混合了 ActionController::TestCase::Behavior
用于 :type =>:api
块.response
将来自 ActionController::TestCase::Behavior
,就像 :type =>:controller
块.
Rspec probably mixes ActionController::TestCase::Behavior
for :type => :api
blocks.
response
would come from ActionController::TestCase::Behavior
, as it does for :type => :controller
blocks.
如果您想在 response
给出的响应之前获得响应,请在发出下一个请求之前尝试将其存储在变量中.
If you want to get the response before that given by response
, try storing it in a variable before you make the next request.
