如何用rspec测试设计视图

Question

我想用rspec测试我的注册视图。

我尝试过很多类似于Testing devise views with rspec或Testing Views that use Devise with RSpec这样的方法

但似乎什么都没问题，我总是会犯这样的错误：

undefined local variable or method `resource'

或

does not implement: resource

我目前的规格(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

我做错了什么？谢谢你的帮助。

编辑：

我把我的代码移到控制器规范上，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

1.在rails_helper.rb中设置配置

RSpec.configure do |config|
  config.include Devise::Test::ControllerHelpers, type: :view
  config.include Devise::Test::ControllerHelpers, type: :controller

  # add these if you need other type of rspec.
  # config.include Devise::Test::IntegrationHelpers, type: :feature
  # config.include Devise::Test::IntegrationHelpers, type: :request
end

2.您的看法Rspec。

# frozen_string_literal: true
require 'rails_helper'

RSpec.describe 'rendering locals in a partial', type: :view do
  let(:user) { create(:user) }

  before :each do
    sign_in user
  end

  it "displays the widget" do
    widget = Widget.create!(:name => "slicer")

    render :partial => "widgets/widget.html.erb", :locals => {:widget => widget}

    expect(rendered).to match /slicer/
  end
  end
end

看看凯巴拉宝石。这里是一个很好的指南，让您开始(https://github.com/eliotsykes/rspec-rails-examples#capybara-examples)。

他也想出了例子(spec.rb)。
