ActiveRecord報告驗證失敗，但沒有定義驗證

Question

我剛剛開始在新項目中使用RSpec（在成爲最小用戶一段時間後）。我創建了一個叫做合同的MVC。下面是模型文件：

class Contract < ActiveRecord::Base 
    attr_accessible :name, :number, :plannedStart, :actualStart, :plannedCompletion, :actualCompletion 
end 

我已經得到了合同規定的基本工廠（這是稍微複雜一些較早，使用序列來生成新的姓名和電話號碼，但我刪除了所有的，要儘量簡化擠壓這個bug）：

FactoryGirl.define do 

    factory :contract do 

    end 
end 

這裏是產生（幾乎是自動的規格，除了我在調用工廠）補充說：

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

describe ContractsController do 
    render_views 

    it "index action should render index template" do 
    create(:contract) 
    get :index 
    response.should render_template(:index) 
    end 

    it "show action should render show template" do 

    create(:contract) 
    get :show, :id => Contract.first 
    response.should render_template(:show) 
    end 

    it "new action should render new template" do 
    get :new 
    response.should render_template(:new) 
    end 

    it "create action should render new template when model is invalid" do 

    Contract.any_instance.stubs(:valid?).returns(false) 
    post :create 
    response.should render_template(:new) 
    end 

    it "create action should redirect when model is valid" do 

    Contract.any_instance.stubs(:valid?).returns(true) 
    post :create 
    response.should redirect_to(contract_url(assigns[:contract])) 
    end 

    it "edit action should render edit template" do 
    create(:contract) 
    get :edit, :id => Contract.first 
    response.should render_template(:edit) 
    end 

    it "update action should render edit template when model is invalid" do 
    create(:contract) 
    Contract.any_instance.stubs(:valid?).returns(false) 
    put :update, :id => Contract.first 
    response.should render_template(:edit) 
    end 

    it "update action should redirect when model is valid" do 
    create(:contract) 
    create(:contract) 
    Contract.any_instance.stubs(:valid?).returns(true) 
    put :update, :id => Contract.first 
    response.should redirect_to(contract_url(assigns[:contract])) 
    end 

    it "destroy action should destroy model and redirect to index action" do 
    create(:contract) 
    contract = Contract.first 
    delete :destroy, :id => contract 
    response.should redirect_to(contracts_url) 
    Contract.exists?(contract.id).should be_false 
    end 
end 

當我運行規範，我得到以下錯誤消息，但我得到的這些數量從運行不同運行：

ActiveRecord::RecordInvalid: Validation failed: 
./spec/controllers/contracts_controller_spec.rb:39:in `block (2 levels) in <top (required)>'

我實現Databasecleaner只是爲了確保這不是與測試過程中使用事務的一些奇怪的行爲問題，但無濟於事。建議？我沒有定義任何驗證，所以很難理解我如何驗證失敗。

Answer 1

存根：for valid？掛在兩次測試之間，所以我把以下內容放在before（：each）塊中：Contract.any_instance.unstub（：valid？），它清除了所有東西。
