Rails集成測試與設計寶石

Question

我想寫一個rails集成測試（使用ActionDispatch::IntegrationTest ）。 我正在使用設計驗證和測試模型的機械師。 我無法成功登錄。

這是一個簡單的例子：

class UserFlowsTest < ActionDispatch::IntegrationTest
  setup do
    User.make
  end
  test "sign in to the site" 
    # sign in
    post_via_redirect 'users/sign_in', :email => 'foo@bar.com', :password => 'qwerty'    
    p flash
    p User.all
end

這是調試輸出：

Loaded suite test/integration/user_flows_test
Started
{:alert=>"Invalid email or password."}
[#<User id: 980190962, email: "", encrypted_password: "", password_salt: "", reset_password_token: nil, remember_token: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: "2010-11-27 16:44:10", updated_at: "2010-11-27 16:44:10">, #<User id: 980190963, email: "foo@bar.com", encrypted_password: "$2a$10$vYSpjIfAd.Irl6eFvhJL0uAwp4qniv5gVl4O.Hnw/BUR...", password_salt: "$2a$10$vYSpjIfAd.Irl6eFvhJL0u", reset_password_token: nil, remember_token: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: "2010-11-27 17:09:13", updated_at: "2010-11-27 17:09:13">]
"/unauthenticated"

這是我的blueprints.rb：

require 'machinist/active_record'
require 'sham'

User.blueprint do
  email {"foo@bar.com"}
  password {"qwerty"}
end

Answer 1

它不起作用的原因是設計創建表單字段名稱為

'user[email]'
'user[password]'

和post_via_redirect期望這些名稱作為參數。 因此，以下聲明將成功登錄。

post_via_redirect 'users/sign_in', 'user[email]' => 'foo@bar.com', 'user[password]' => 'qwerty' 

Answer 2

首先，通過設計，您可能必須“確認”用戶。

你可以這樣做：

user = User.make!
user.confirmed_at = Time.now
user.save!

這是一個沒有Machinist的例子（但你必須用上面的部分替換用戶創建代碼部分）：

進入test_integration_helper：

require "test_helper"
require "capybara/rails"

    module ActionController
      class IntegrationTest
        include Capybara

        def sign_in_as(user, password)
           user = User.create(:password => password, :password_confirmation => password, :email => user)
           user.confirmed_at = Time.now 
           user.save!
           visit '/'
           click_link_or_button('Log in')
           fill_in 'Email', :with => user.email
           fill_in 'Password', :with => password
           click_link_or_button('Sign in')
           user      
         end 
         def sign_out
            click_link_or_button('Log Out')   
         end
      end
    end

進入你的integration_test：

require 'test_integration_helper'

class UsersIntegrationTest < ActionController::IntegrationTest

  test "sign in and then sign out" do 
    #this helper method is into the test_integration_helper file                   
    sign_in_as("lolz@gmail.com", "monkey")         
    assert page.has_content?('Signed in successfully'), "Signed in successfully"

    sign_out         
    assert page.has_content?('Signed out successfully'), "Signed out successfully" 
  end
end

Answer 3

我沒有在Devise的書中進行樣本集成測試，但我認為如果安裝了Webrat / Capybara，Cucumber章節中步驟定義中的代碼也會起作用：

@user = User.create!(:email => "email@email.com",  
            :password => "password",  
            :password_confirmation => "password")
visit "login"  
fill_in("user_email", :with => @user.email)  
fill_in("user_password", :with => "password") 
click_button("Sign In")

Answer 4

如果其他人有類似的問題......

我處於類似的情況（從Authlogic遷移），並有這個完全相同的問題。 問題出在devise.rb初始化程序中。 默認情況下，它會將您的測試環境設置為在加密/解密密碼期間僅使用1次拉伸。 老實說，我不知道是什么延伸，但是對於Devise使用舊的Authlogic加密密碼，延伸必須是20.因為我試圖在我的測試中簽署一個最初由Authlogic加密密碼的用戶，設計也需要在測試中使用20個延伸。 我更改了如下配置：

# Limiting the stretches to just one in testing will increase the performance of
# your test suite dramatically. However, it is STRONGLY RECOMMENDED to not use
# a value less than 10 in other environments.
-  config.stretches = Rails.env.test? ? 1 : 20
+  config.stretches = 20

Answer 5

由於您使用的是ActionDispatch::IntegrationTest ，因此您可以包含Devise::Test::IntegrationHelpers模塊並使用sign_in方法（您可以將用戶傳遞給它）：

class UserFlowsTest < ActionDispatch::IntegrationTest
  include Devise::Test::IntegrationHelpers

  test "sign in to the site" do
    sign_in users(:one)
  end
end
