ruby-on-rails - 如何 stub users_controller | authlogic, rspec2, rails3, factory_girl

Question

我的 users_controller.rb

# GET /users/1/edit
def edit
  @user = current_user
  #@user = User.find(params[:id])
end

我可爱的 ​​users_controller_spec.rb(注意我所有被注释掉的尝试)

describe "Authenticated examples" do
  before(:each) do
    activate_authlogic
    UserSession.create Factory.build(:valid_user)
  end

describe "GET edit" do
  it "assigns the requested user as @user" do
    @user = Factory.create(:valid_user)
    assigns(:user).should be(Factory.build(:valid_user))
  end
end

user.rb - 工厂

Factory.define :valid_user, :class => User do |u|
  u.username "Trippy"
  u.password "password"
  u.password_confirmation "password"
  u.email "elephant@gmail.com"
  u.single_access_token "k3cFzLIQnZ4MHRmJvJzg"
end

基本上我只是想让这个 RSpec 测试以最合适的方式通过。

我需要能够非常简单地说，mock_user 就是 current_user。

如果我在 users_controller.rb 中使用 @user = User.find(params[:id])

，则此测试通过

谢谢!!

rspec-rails 中有一个错误(参见 https://github.com/rspec/rspec-rails/issues/391)，当在 RSpec 的全局 before 钩子(Hook)中使用时，它会破坏 activate_authlogic。

代替

# spec_helper.rb

# In RSpec.configure
config.before :each, :type => :controller do
  activate_authlogic
  user = User.new(:login => "user", :password => "secret")
  UserSession.create(user)
end

你可以定义一个助手

# spec_helper.rb

require 'authlogic/test_case'
module LoginHelper
  include Authlogic::TestCase

  def login_user
    activate_authlogic
    user = User.new(:login => "user", :password => "secret")
    UserSession.create(user)
  end
end

并在需要时在 before block 中引用它

# <controller>_spec.rb

describe "GET 'edit' when logged in" do
  before do
    login_user
  end

  it "should be successful" do
    get 'edit'
    response.should be_success
end
