我的问题

它运行的场景但在我运行测试时在控制台中bin/rspec）我收到此警告：

  

弃用警告：

我的场景

app/controllers/application_controller.rb

class ApplicationController < ActionController::Base
  include ExtraContent
end

app/controllers/concerns/extra_content.rb

module ExtraContent
  extend ActiveSupport::Concern

  included do
    helper_method :extra_content?
  end

  def extra_content?
    current_user.premium?
  end
end

app/controllers/concerns/extra_content.rb

module ExtraContent
  extend ActiveSupport::Concern

  included do
    helper_method :extra_content?
  end

  def extra_content?
    current_user.premium?
  end
end

app/views/users/show.html.haml

%h1= @user.name
- if extra_content?
  %span.premium PREMIUM

spec/features/premium_spec.rb

feature 'Premium features' do
  scenario 'premium user can view extra content' do
    ApplicationController.any_instance.stub(:extra_content?).and_return(true)

    visit '/users/1'
    expect(page).to have_content 'PREMIUM'
  end
end

改变这个：

<强> spec/features/premium_spec.rb

feature 'Premium features' do
  scenario 'premium user can view extra content' do
    ApplicationController.any_instance.stub(:extra_content?).and_return(true)

    visit '/users/1'
    expect(page).to have_content 'PREMIUM'
  end
end

为此：

<强> spec/features/premium_spec.rb

feature 'Premium features' do
  scenario 'premium user can view extra content' do
    allow_any_instance_of(ApplicationController).to receive(:extra_content?).and_return(true)

    visit '/users/1'
    expect(page).to have_content 'PREMIUM'
  end
end
