如何使用RSpec測試Devise Sessions控制器

Question

我在自己的控制器中重寫了SessionsController，並嘗試使用RSpec進行測試。拳，我設置與

@request.env["devise.mapping"] = Devise.mappings[:user] 

我的規格設計：

require 'rails_helper' 

需要 'authentication_helper'

RSpec.describe用戶:: SessionsController，類型：控制器不 包括AuthenticationHelper

描述'創建新會話'做

before(:each) do 
    setup_auth 
end 

let(:user) {FactoryGirl.create(:user, username: 'john', email: 'john@gmail.com', password: 'pwd1234')} 

it 'should return 200 with valid username and password' do 
    post :create, user: {login: 'john', password: 'pwd1234'} 

    expect(response).to have_http_status 200 
    expect(controller.current_user.id).to eq(user.id) 
end 

末 結束

我SessionsController只是返回HTTP 401或HTTP 200 當我跑我的天賦，我得到這個錯誤：

NoMethodError： 未定義的方法authenticate?' for nil:NilClass # /usr/local/bundle/gems/devise-3.5.6/app/controllers/devise_controller.rb:103:in require_no_authentication」 ＃./spec /controllers/users/sessions_controller_spec.rb:16:in block (3 levels) in <top (required)>' # ./spec/rails_helper.rb:45:in' ＃/usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/generic/base.rb:16:in中的塊（3個級別） cleaning' # /usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/base.rb:98:in清理' ＃/ usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/configuration.rb：86：在block (2 levels) in cleaning' # /usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/configuration.rb:87:in調用' ＃/usr/local/bundle/gems/database_cleaner-1.6.0/lib/database_cleaner/configuration.rb ：87：cleaning' # ./spec/rails_helper.rb:44:in block（2 levels）in'

我在做什麼錯？

你應該在籤一個幫手，例如

module AuthenticationHelpers 
    module Controller 
     def sign_in(user) 
      controller.stub(:current_user).and_return(user) 
      controller.stub(:user_id).and_return(user.id) 
     end 
    end 

    module Feature 
     def sign_in(user, options={}) 
      visit "https://stackoverflow.com/users/sign_in" 
      fill_in "Email", with: user.email 
      fill_in "Password", with: options[:password] 
      click_button "Log in" 
     end 
    end 
end
