在视图规范中模拟变量

Question

以下是我尝试规范的观点：

%h2 Sign up

= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f|
    = devise_error_messages!
    %br= f.label :email 
    %br= f.email_field :email, autofocus: true
    %br= f.label :password
    %br= f.password_field :password, autocomplete: 'off'
    %br= f.label :password_confirmation
    %br= f.password_field :password_confirmation, autocomplete: 'off'
    = f.submit 'Sign up'

= render 'devise/shared/links'

这是我的规格：

require 'spec_helper'

describe 'devise/registrations/new', js: true, type: :view do
    it 'has a name field' do 
      render
      rendered.should contain('Email')
    end
end

返回错误undefined local variable or method 'resource'。

我当时正在等待。我需要存根变量。

将它放在渲染函数之前：

expect(view).to receive(:resource).and_return(stub_model(User))

结果：

  An error occurred in an `around(:example)` hook
    NoMethodError: undefined method `method_removed' for #<User not initialized>
    occurred at /usr/local/rvm/gems/ruby-2.0.0-p0/gems/activemodel-4.1.1/lib/active_model/attribute_methods.rb:435:in `method_missing'

和

does not implement: resource

我认为这意味着视图没有实现资源......
