Rspec的越來越「堆棧層次過深，」從協會

Question

對於控制器測試，在我定義的模型規範的頂部：

let(:user) { Factory(:user, :company => company) } 
    let(:facility) { Factory(:facility, :company => company) } 
    let(:company) { Factory(:company, :facilities => [facility]) } 

，並做基本指標規格：

context "responding to GET index" do 
    it "should expose all facilities as @facilities" do 
     user.company.should_receive(:facilities).and_return([facility]) 
     get :index 
     assigns[:facilities].should == [facility] 
    end 
    end 

但我發現了這個錯誤：

should expose all facilities as @facilities 
stack level too deep 
/Users/dmix/.rvm/gems/ruby-1.9.3-p0/gems/rspec-core-2.6.4/lib/rspec/core/let.rb:90 
88  module InstanceMethods 
89  def __memoized # :nodoc: 
90   @__memoized ||= {} 
91  end 
92  end 

這個問題似乎在同一時間被引用的3家工廠。

如果我刪除：從公司工廠定義設施，堆棧錯誤去的方式：

let(:company) { Factory(:company) } 

我怎麼廠三個型號，所有沒有得到一個計算器相互引用？

Answer 1

問題是您的facility和company對象互相引用。我認爲您的company工廠的:facilities => [facility]部分可能是不必要的，因爲您已指定facility對象的公司爲company。試試這個：

let(:facility) { Factory(:facility, :company => company) } 
let(:company) { Factory(:company) }
