ruby-on-rails - 如何使用 rspec 测试设计 View

Question

我想用 rspec 测试我的注册 View 。

我已经尝试了很多类似这里建议的方法 Testing devise views with rspec
或 Testing Views that use Devise with RSpec

但似乎什么都没有，我总是收到如下错误:

undefined local variable or method `resource'

或者

does not implement: resource

我目前的规范(spec/views/devise/registrations/new.slim_spec.rb):

require 'rails_helper'

RSpec.describe 'devise/registrations/new.slim', type: :view do

  describe 'sign up form' do

    before do
      allow(view).to receive(:resource).and_return(User.new)
      allow(view).to receive(:resource_name).and_return(:user)
    end

    it 'does not contains an area for user avatar' do
      render
      expect(rendered).to_not include('Profile Pic')
    end
  end
end 

我的环境:

rails 4.2.3

设计 3.5.1

rspec 3.3.0

我究竟做错了什么？谢谢你的帮助。

编辑:

我将我的代码移动到 Controller 规范并且它可以工作，并不完美但是......

RSpec.describe Users::RegistrationsController, type: :controller do
  before(:each) do
    request.env['devise.mapping'] = Devise.mappings[:user]
  end

  describe '#new' do
    render_views

    it 'does not contains an area for user avatar' do
      get :new
      expect(response.body).to_not include('Profile Pic')
    end
  end
end

查看 capybara gem 。这是一个很好的入门指南( https://github.com/eliotsykes/rspec-rails-examples#capybara-examples )。

他也设计了一些例子，(https://github.com/eliotsykes/rspec-rails-examples/blob/master/spec/features/user_registers_spec.rb)。
