如何将Ruby MiniTest :: Spec与Rails一起用于API集成测试? [英] How to use Ruby MiniTest::Spec with Rails for API integration tests?

问题描述

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.

I'm building an app including a Rails API and want to use Ruby MiniTest::Spec to test.

设置它的好方法是什么?

What's a good way to set it up?

例如，良好的目录组织，良好的文件包含方式等等?

For example, good directory organization, good way to include files, etc.?

我正在使用《 Rails 3 In Action》一书中的指南，该书使用RSpec并在API上有很好的论述.最大的变化是选择了MiniTest :: Spec.

I'm using the guidelines in the book Rails 3 In Action which uses RSpec and has a great chapter on APIs. The big change is preferring MiniTest::Spec.

Answering with what I've found so far in case it's helpful to other developers....

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

ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)

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

spec/factories/item.rb

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

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

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