Rspec 控制器发布请求以呈现不同的部分

Question

我正在尝试编写一个控制器规范来测试正确的部分是否在发布请求后呈现。

这是发布到的控制器方法：

def lookup
@guest = Guest.where("mobile_number = ?", params[:lookup_mobile_phone_number]).first_or_initialize do |g|
  g.mobile_number = params[:lookup_mobile_phone_number]
end
if @guest.new_record?
  @visit = Visit.new(hotel_id: params[:hotel_id])
  render partial: "guests/form"
else
  @visit = Visit.new(guest_id: @guest.id, hotel_id: params[:hotel_id])
  render partial: "visits/form"
end
end

这是我写的失败的 spec/controllers/guests_controller_spec.rb：

RSpec.describe GuestsController, :type => :controller do
describe "#lookup" do
render_views
let!(:returning_guest) { create(:test_guest) }
    context "when guest is already registered with hotel" do
      it "renders visits/form" do
        post :lookup, :guest => { :lookup_mobile_phone_number => "5553331212"}
        expect(response).to render_template(:partial => 'visits/form')
      end
   end
end
end

这是我用于 :test_guest 的工厂

FactoryGirl.define do
  factory :test_guest, :class => 'Guest' do
    name 'Jack Guest'
    mobile_number '5553331212'
  end
end

这是我在测试失败时得到的响应

 1) GuestsController#lookup when guest is already registered with hotel renders visits/form
     Failure/Error: expect(response).to render_template(:partial => 'visits/form')
     expecting partial <visits/form> but action rendered <["shared/_hotel_agent_name",     "_hotel_agent_name", "guests/_form", "_form"]>.
   Expected {"shared/_hotel_agent_name"=>1, "_hotel_agent_name"=>1, "guests/_form"=>1, "_form"=>1} to include "visits/form".
 # ./spec/controllers/guests_controller_spec.rb:16:in `block (4 levels) in <top (required)>'

我这几天一直在研究这个问题，尝试在这里找到的不同方法，但没有运气。任何帮助将不胜感激:)

Answer 1

你发送

post :lookup, :guest => { :lookup_mobile_phone_number => "5553331212"}

但在控制器中，您使用

params[:lookup_mobile_phone_number]

不是

params[:guest][:lookup_mobile_phone_number]

所以要修复它，根据你的控制器，做

post :lookup, :lookup_mobile_phone_number => "5553331212"
