RSpec controller test error: controller does not implement method

Question

我已经为 Devise 注册编写了一些自定义代码。也就是说，一旦用户点击 "sign up" 按钮，Devise 的通用代码就会确保用户被正确保存。但是，我想进去并确保用户获得关联的 Stripe 客户帐户。以下大部分代码来自 Devise，除了我添加的几行代码：

class Users::RegistrationsController < Devise::RegistrationsController
def create
  build_resource(sign_up_params)
  resource.save
  yield resource if block_given?
  if resource.persisted?
    #### If statement below is the key custom code ####
    if create_stripe_customer
      #### Back to default Devise code ####
      if resource.active_for_authentication?
        set_flash_message :success, :signed_up if is_flashing_format?
        sign_up(resource_name, resource)
        respond_with resource, location: after_sign_up_path_for(resource)
      else
        set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_flashing_format?
        expire_data_after_sign_in!
        respond_with resource, location: after_inactive_sign_up_path_for(resource)
      end
    #### Else statement below is custom ####
    else
      flash[:danger] = flash_messages["not_your_fault"]
      redirect_to root_path
    end
  else
    clean_up_passwords resource
    set_minimum_password_length
    respond_with resource
  end
end 

private

def create_stripe_customer
  new_stripe_customer = StripeService.new({
    source: sign_up_params[:token],
    user_id: self.id 
  })    
  if new_stripe_customer && self.update_attributes(stripe_customer_id: new_stripe_customer.id)
  else
    false
  end
end
end

我现在正在尝试在 create 控制器上编写测试，以确保在 post 到 create 时，我的自定义方法：

获取正确的参数（即，有其他测试可确保该方法使用这些参数做正确的事情），并且 returns 为真，然后用户将被重定向到 after_sign_up_path.在这个例子中，正确的参数是 sign_up_params[:token] 被传递给 create_stripe_customer
获取错误的参数和 returns 错误，根据我的自定义代码

root_path

这是我目前的 RSpec 文件：

describe Users::RegistrationsController, "Create action" do

  before do
    request.env['devise.mapping'] = Devise.mappings[:user]
  end

  it "Successful creation" do
    Users::RegistrationsController.should_receive(:create_stripe_customer).with(source: "test" , user_id: @user.id).and_return(false)
    post :create, sign_up: { first_stripe_token: "test" }
  end
end

然而，当我运行它时，我得到：

Failure/Error: Users::RegistrationsController.should_receive(:create_stripe_customer).with(source: "test" , user_id: @user.id).and_return(false)
   Users::RegistrationsController does not implement: create_stripe_customer

不确定为什么控制器没有执行该方法...

您将 create_stripe_customer 存根为 class 方法，但它实际上是一个实例方法。
