rspec 中的 mock_model 错误

Question

这是在控制器中创建的 rspec 代码：

describe "'create' successful" do
  before(:each) do

    @customer = mock_model(Customer)
    @customer.stub(:save).and_return(true) 

    session[:sales] =  true
    session[:user_id] = 1
    session[:user_name] = "sales.name"
    session[:page_step] = 1
    session['page1'] = customers_path
  end

  it "should create one customer record" do
    lambda do
      put 'create', @customer         
    end.should change(Customer, :count).by(1)
  end

  it "should redirect to customers path" do
    put 'create', @customer
    flash[:notice].should_not be_nil
    response.should redirect_to(customers_path)
  end
end

这是在控制器中创建：

  def create

    if session[:sales]
      @customer = Customer.new(params[:customer], :as => :roles_new_update)
      @customer.sales_id = session[:user_id]
      if @customer.save
        @message = "New customer #{params[:name]} was created. Please check it out"
        @subject = "New customer #{params[:name]} was created BY {#session[:user_name]}"
        UserMailer.notify_tl_dh_ch_ceo(@message, @subject, session[:user_id])
        redirect_to session[('page' + session[:page_step].to_s).to_sym], :notice => 'Customer was created successfaully!'          
      else
        render 'new', :notice => 'Customer was not saved!'
      end
    end
  end

这是 rspec 中的错误：

  1) CustomersController GET customer page 'create' successful should create one customer record
     Failure/Error: put 'create', @customer
     NoMethodError:
       undefined method `symbolize_keys' for "1001":String
     # ./spec/controllers/customers_controller_spec.rb:40:in `block (5 levels) in <top (required)>'
     # ./spec/controllers/customers_controller_spec.rb:39:in `block (4 levels) in <top (required)>'

  2) CustomersController GET customer page 'create' successful should redirect to customers path
     Failure/Error: put 'create', @customer
     NoMethodError:
       undefined method `symbolize_keys' for "1002":String
     # ./spec/controllers/customers_controller_spec.rb:45:i

问题在于@customer 的模拟数据。规范中的嘲笑有什么问题？

谢谢。

Answer 1

没有错，您只需让模型获取您创建的模拟。

继续往下：

@customer = mock_model(Customer)
@customer.stub(:save).and_return(true) 
Customer.should_receive(:new).and_return(@customer)

重读您的问题，我发现 Rails 可能会抱怨，因为当您将变量传递给路由时，它应该响应 to_param。

但你的模拟没有：它什么都不是。

我会说从以下选项中进行选择：

• 使用具有正确属性的真实 ActiveRecord 对象的 Factory

• 为put 'create', 1234 或您想要的任何整数编辑您的测试。

顺便说一句，put 触发了 update 操作，该操作不应该创建对象而只是更改它们。
