在请求规范中存根身份验证

发布于 2024-11-03 18:55:23 字数 1738 浏览 3 评论 0原文

在编写请求规范时,如何设置会话和/或存根控制器方法? 我正在尝试在集成测试中消除身份验证 - rspec/requests

这是一个测试示例

require File.dirname(__FILE__) + '/../spec_helper'
require File.dirname(__FILE__) + '/authentication_helpers'


describe "Messages" do
  include AuthenticationHelpers

  describe "GET admin/messages" do
    before(:each) do
      @current_user = Factory :super_admin
      login(@current_user)
    end

    it "displays received messages" do
      sender = Factory :jonas
      direct_message = Message.new(:sender_id => sender.id, :subject => "Message system.", :content => "content", :receiver_ids => [@current_user.id])
      direct_message.save
      get admin_messages_path
      response.body.should include(direct_message.subject) 
    end
  end
end

助手:

module AuthenticationHelpers
  def login(user)
    session[:user_id] = user.id # session is nil
    #controller.stub!(:current_user).and_return(user) # controller is nil
  end
end

以及处理身份验证的 ApplicationController:

class ApplicationController < ActionController::Base
  protect_from_forgery

  helper_method :current_user
  helper_method :logged_in?

  protected

  def current_user  
    @current_user ||= User.find(session[:user_id]) if session[:user_id]  
  end

  def logged_in?
    !current_user.nil?
  end
end

为什么无法访问这些资源?

1) Messages GET admin/messages displays received messages
     Failure/Error: login(@current_user)
     NoMethodError:
       undefined method `session' for nil:NilClass
     # ./spec/requests/authentication_helpers.rb:3:in `login'
     # ./spec/requests/message_spec.rb:15:in `block (3 levels) in <top (required)>'

When writing a request spec, how do you set sessions and/or stub controller methods?
I'm trying to stub out authentication in my integration tests - rspec/requests

Here's an example of a test

require File.dirname(__FILE__) + '/../spec_helper'
require File.dirname(__FILE__) + '/authentication_helpers'


describe "Messages" do
  include AuthenticationHelpers

  describe "GET admin/messages" do
    before(:each) do
      @current_user = Factory :super_admin
      login(@current_user)
    end

    it "displays received messages" do
      sender = Factory :jonas
      direct_message = Message.new(:sender_id => sender.id, :subject => "Message system.", :content => "content", :receiver_ids => [@current_user.id])
      direct_message.save
      get admin_messages_path
      response.body.should include(direct_message.subject) 
    end
  end
end

The helper:

module AuthenticationHelpers
  def login(user)
    session[:user_id] = user.id # session is nil
    #controller.stub!(:current_user).and_return(user) # controller is nil
  end
end

And the ApplicationController that handles authentication:

class ApplicationController < ActionController::Base
  protect_from_forgery

  helper_method :current_user
  helper_method :logged_in?

  protected

  def current_user  
    @current_user ||= User.find(session[:user_id]) if session[:user_id]  
  end

  def logged_in?
    !current_user.nil?
  end
end

Why is it not possible to access these resources?

1) Messages GET admin/messages displays received messages
     Failure/Error: login(@current_user)
     NoMethodError:
       undefined method `session' for nil:NilClass
     # ./spec/requests/authentication_helpers.rb:3:in `login'
     # ./spec/requests/message_spec.rb:15:in `block (3 levels) in <top (required)>'

请求规范是 ActionDispatch::IntegrationTest 的薄包装,它不像控制器规范那样工作(它包装 ActionController::TestCase)。尽管有可用的会话方法,但我认为它不受支持(即它可能存在,因为其他实用程序包含的模块也包含该方法)。

我建议通过发布到您用来验证用户身份的任何操作来登录。如果您为所有用户工厂设置密码“password”(例如),那么您可以执行以下操作:

def login(user)
  post login_path, :login => user.login, :password => 'password'
end

A request spec is a thin wrapper around ActionDispatch::IntegrationTest, which doesn't work like controller specs (which wrap ActionController::TestCase). Even though there is a session method available, I don't think it is supported (i.e. it's probably there because a module that gets included for other utilities also includes that method).

I'd recommend logging in by posting to whatever action you use to authenticate users. If you make the password 'password' (for example) for all the User factories, then you can do something like this:

def login(user)
  post login_path, :login => user.login, :password => 'password'
end

Devise 用户请注意...

顺便说一句,如果您使用 Devise。我在集成/请求测试中所做的事情(感谢 这篇 StackOverflow 帖子):

# file: spec/requests_helper.rb

# Rails 6
def login(user)
  post user_session_path, params: {
    user: {
      email: user.email, password: user.password
    }
  }
  follow_redirect!
end

# Rails 5 or older
def login(user)
  post_via_redirect user_session_path, 'user[email]' => user.email, 'user[password]' => user.password
end

Note for Devise users...

BTW, @David Chelimsky's answer may need a little tweaking if you're using Devise. What I'm doing in my integration / requests testing (thanks to this StackOverflow post):

# file: spec/requests_helper.rb

# Rails 6
def login(user)
  post user_session_path, params: {
    user: {
      email: user.email, password: user.password
    }
  }
  follow_redirect!
end

# Rails 5 or older
def login(user)
  post_via_redirect user_session_path, 'user[email]' => user.email, 'user[password]' => user.password
end

FWIW,在将我的 Test::Unit 测试移植到 RSpec 时,我希望能够在我的请求规范中使用多个(设计)会话登录。需要一些挖掘,但让它对我有用。使用 Rails 3.2.13 和 RSpec 2.13.0。

# file: spec/support/devise.rb
module RequestHelpers
  def login(user)
    ActionController::IntegrationTest.new(self).open_session do |sess|
      u = users(user)

      sess.post '/users/sign_in', {
        user: {
          email: u.email,
          password: 'password'
        }
      }

      sess.flash[:alert].should be_nil
      sess.flash[:notice].should == 'Signed in successfully.'
      sess.response.code.should == '302'
    end
  end
end

include RequestHelpers

并且...

# spec/request/user_flows.rb
require 'spec_helper'

describe 'User flows' do
  fixtures :users

  it 'lets a user do stuff to another user' do
    karl = login :karl
    karl.get '/users'
    karl.response.code.should eq '200'

    karl.xhr :put, "/users/#{users(:bob).id}", id: users(:bob).id,
      "#{users(:bob).id}-is-funny" => 'true'

    karl.response.code.should eq '200'
    User.find(users(:bob).id).should be_funny

    bob = login :bob
    expect { bob.get '/users' }.to_not raise_exception

    bob.response.code.should eq '200'
  end
end

编辑:修复了拼写错误

FWIW, in porting my Test::Unit tests to RSpec, I wanted to be able to login with multiple (devise) sessions in my request specs. It took some digging, but got this to work for me. Using Rails 3.2.13 and RSpec 2.13.0.

# file: spec/support/devise.rb
module RequestHelpers
  def login(user)
    ActionController::IntegrationTest.new(self).open_session do |sess|
      u = users(user)

      sess.post '/users/sign_in', {
        user: {
          email: u.email,
          password: 'password'
        }
      }

      sess.flash[:alert].should be_nil
      sess.flash[:notice].should == 'Signed in successfully.'
      sess.response.code.should == '302'
    end
  end
end

include RequestHelpers

And...

# spec/request/user_flows.rb
require 'spec_helper'

describe 'User flows' do
  fixtures :users

  it 'lets a user do stuff to another user' do
    karl = login :karl
    karl.get '/users'
    karl.response.code.should eq '200'

    karl.xhr :put, "/users/#{users(:bob).id}", id: users(:bob).id,
      "#{users(:bob).id}-is-funny" => 'true'

    karl.response.code.should eq '200'
    User.find(users(:bob).id).should be_funny

    bob = login :bob
    expect { bob.get '/users' }.to_not raise_exception

    bob.response.code.should eq '200'
  end
end

Edit: fixed typo

您也可以很容易地对会话进行存根。

controller.session.stub(:[]).with(:user_id).and_return(<whatever user ID>)

所有 ruby​​ 特殊运算符确实都是方法。调用1+11.+(1)相同,这意味着+只是一个方法。同样,session[:user_id] 与在 session 上调用方法 [] 相同,如 session.[](:user_id )

You could pretty easily stub the session as well.

controller.session.stub(:[]).with(:user_id).and_return(<whatever user ID>)

All ruby special operators are indeed methods. Calling 1+1 is the same as 1.+(1), which means + is just a method. Similarly, session[:user_id] is the same as calling method [] on session, as session.[](:user_id)
