Padrino，为Capybara安装应用程序

Question

我有一个特性spec: /spec/posts/post_posts_spec.rb：

require 'spec_helper'

describe "Displaying Posts" do
  it "can see posts on posts page" do
    Post.create(title: "Title", content: "Content")
    visit '/posts'
    expect(page).to have_content("Title")
    expect(page).to have_content("Content")
  end
end

当我做测试时，我得到：

WARNING! No apps are mounted. Please, mount apps in `config/apps.rb`

以及一次失败的考试，包括：

NameError:
       uninitialized constant Post

/spec/spec_helper.rb：

require 'rack/test'
require 'rspec/padrino'
require 'capybara/rspec'

Capybara.app = Padrino.application

RSpec.configure do |config|
  config.include Rack::Test::Methods
  config.include RSpec::Padrino
  config.include Capybara::DSL

  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end
end

/Gemfile：

source 'https://rubygems.org'

ruby '2.3.0'

# Project requirements
gem 'rake'

# Component requirements
gem 'bcrypt'
gem 'sass'
gem 'haml'
gem 'activerecord', '>= 3.1', :require => 'active_record'
gem 'sqlite3'

# Test requirements

  gem 'rack-test', :require => 'rack/test'
  gem 'rspec-padrino'
  gem 'capybara'
end

# Padrino Stable Gem
gem 'padrino', '0.13.1'

/app/app.rb：

module PadrinoBlog
  class App < Padrino::Application
    register SassInitializer
    use ConnectionPoolManagement
    register Padrino::Mailer
    register Padrino::Helpers

    enable :sessions

    get "/" do
      "Hello World!"
    end

    get :about, :map => '/about_us' do
      render :haml, "%p This is a sample blog created to demonstrate how Padrino works!"
    end
  end
end

/config/apps.rb：

Padrino.configure_apps do
  # enable :sessions
  set :session_secret, '67c26da8db30eaf68907e2de05783d33be5e246b87c194f0579bdb589c0761dd'
  set :protection, :except => :path_traversal
  set :protect_from_csrf, true
end

# Mounts the core application for this project

Padrino.mount("PadrinoBlog::Admin", :app_file => Padrino.root('admin/app.rb')).to("/admin")
Padrino.mount('PadrinoBlog::App', :app_file => Padrino.root('app/app.rb')).to('/')

我尝试过各种不同的方法，比如在spec_helper中要求“spec_helper”文件，这就导致不得不在那里要求active_record，这就导致了一个问题，因为它不知道SassInitializer是什么，不知道是什么。

老实说，我真的不知道我在做什么，也不知道每件事是如何整合在一起的，所以任何帮助都是非常感激的。

回购的分支这里。

我从未使用过padrino，但似乎您在spec_helper顶部缺少了几行代码，这些行实际上会加载应用程序资源。

RACK_ENV = 'test' unless defined?(RACK_ENV)
require File.expand_path(File.dirname(__FILE__) + "/../config/boot")
Dir[File.expand_path(File.dirname(__FILE__) + "/../app/helpers/**/*.rb")].each(&method(:require))
