ruby-on-rails - 如何使用 Ruby MiniTest::Spec 和 Rails 进行 API 集成测试？

Question

我正在构建一个包含 Rails API 的应用程序，并希望使用 Ruby MiniTest::Spec 进行测试。

设置它的好方法是什么？

例如，良好的目录组织、包含文件的好方法等？

我正在使用 Rails 3 In Action 一书中的指南，该书使用 RSpec 并且有一个关于 API 的重要章节。最大的变化是更喜欢 MiniTest::Spec。

用我目前发现的内容来回答，以防对其他开发人员有帮助....

规范/api/items_spec.rb

require 'spec_helper'

class ItemsSpec < ActionDispatch::IntegrationTest

  before do
    @item = Factory.create(:item)
  end

  describe "items that are viewable by this user" do
    it "responds with good json" do
      get "/api/items.json"
      response.success?.must_equal true
      body.must_equal Item.all.to_json
      items = JSON.parse(response.body)
      items.any?{|x| x["name"] == @item.name}.must_equal true
    end
  end

end

规范/spec_helper.rb

ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)
gem 'minitest'
require 'minitest/autorun'
require 'action_controller/test_case'
require 'capybara/rails'
require 'rails/test_help'
require 'miniskirt'
require 'factories'
require 'mocha'

# Support files                                                                                                                                                                                                                                                                  
Dir["#{File.expand_path(File.dirname(__FILE__))}/support/*.rb"].each do |file|
  require file
end

规范/工厂/item.rb

Factory.define :item do |x|  x.name { "Foo" }end

app/controllers/api/base_controller.rb

class Api::BaseController < ActionController::Base
  respond_to :json
end

app/controllers/api/items_controller.rb

class Api::ItemsController < Api::BaseController
  def index
    respond_with(Item.all)
  end
end

配置/routes.rb

MyApp::Application.routes.draw do
  namespace :api do
    resources :items
  end
end
