好生奇怪紅寶石 '|| =' 和RSpec雙打行爲

運行以下rspec寶石版本：好生奇怪紅寶石 '|| =' 和RSpec雙打行爲

* rspec (2.14.1) 
    * rspec-core (2.14.7) 
    * rspec-expectations (2.14.5) 
    * rspec-mocks (2.14.6) 
    * rspec-rails (2.14.1)

而且octokit 2.7.1

鑑於spec/support/octokit.rb如下：

# This support package contains modules for octokit mocking 

module OctokitHelper 
    def mock_pull_requests_for_org org 
    mock_org_repos(org).map do |repo| 
     mock_pull_requests repo 
    end.flatten 
    end 
    def mock_org_repos org 
    @@repos ||= [ 
     double('Sawyer::Resource', name: 'repo 1'), 
     double('Sawyer::Resource', name: 'repo 2') 
    ] 
    Octokit.stub(:org_repos) { |org=org| @@repos } 
    @@repos 
    end 
    def mock_pull_requests repo, gh_handle=nil 
    @@pulls ||= [ 
     double('Sawyer::Resource', title: 'pr 1'), 
     double('Sawyer::Resource', title: 'pr 2') 
    ] 
    Octokit.stub(:pull_requests) { |repo| @@pulls } 
    @@pulls 
    end 
end 

RSpec.configure do |config| 
    config.include OctokitHelper 
end

每當我嘗試從規範第一次撥打mock_org_repos，@@repos.first.name是repo 1 。第二次左右，@@repos.first.name拋出一個非常奇怪的錯誤：

1) StudentsController GET #submissions renders pull requests template 
    Failure/Error: get :submissions, student_id: 2 
     Double "Sawyer::Resource" received unexpected message :name with (no args)

我的mock_org_repos使用的例子：

require 'spec_helper' 

describe StudentsController do 
    describe 'GET #submissions' do 
    before do 
     @user = FactoryGirl.create(:instructor) 
     @user.stub(:is_instructor?) { true } 
     @submissions = mock_pull_requests_for_org ENV['GA_ORG_NAME'] 
     controller.stub(:current_user) { @user } 
     get :submissions, student_id: 2 
    end 
    it 'assigns @submissions' do 
     assigns(:submissions).should == @submissions 
    end 
    it 'renders pull requests template' do 
     response.should render_template 'submissions' 
    end 
    end 
end
