如何检查的辅助方法/变量rspec的存在？

Question

我还在试图找出rspec的和现在我使用authlogic来处理我的用户会话。我做了通常的authlogic东西，如添加高清CURRENT_USER方法applciation控制器，并作为一个辅助方法，但我怎么访问，在我的RSpec的控制器文件？

下面是我user_sessions_controller_spec.rb：

require 'spec_helper'
require 'authlogic'

describe UserSessionsController do

  context "user is already logged in" do

    before(:each) do
      include Authlogic::TestCase
      activate_authlogic
      UserSession.create Factory.build(:user)
    end

    it "should redirect the user to the home page" do
      get 'new'
      response.should redirect_to(home_path)
    end

  end

  describe "#create" do
    context "when the user is not logged in" do    
      before(:each) do
        current_user = nil
      end

      it "correct authorization should create a new session" do
        post 'create', {:login => "afactoryuser", :password => "apass", :password_confirmation => "apass"}
        current_user.should_not be_nil
      end
    end
  end

end

当我运行rspec的，它只是告诉我：

correct authorization should create a new session
undefined local variable or method `current_user' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_2::Nested_1:0x000001017d3410>

所以即时猜测它是在RSpec的背景下...但我怎么知道它应该在用户sessions_controller？和我我甚至正确的测试它？

在您的RSpec CURRENT_USER的insted的，尽量controller.current_user

如果您想存根CURRENT_USER方法使用：在controller.stub!(:current_user).and_return(whatever) before :each  块，但你总是会得到whatever如果你存根它。
