如何测试Mongoid的嵌入式文档？

debugcn 发表于 Dev

时间压力

我创建了一个以mongoid作为odm的Rails 4应用程序。我可以使用mongoid-rspec gem成功测试所有模型，但无法嵌入文档。我找不到办法。

这是基本模型：

class Project::Type
  include Mongoid::Document
  include Mongoid::Timestamps
  include Mongoid::Paranoia

  store_in session: 'project', collection: 'type'

  embeds_many :rules, :class_name => "Project::TypeRule"

  field :name, type: String
  field :timing, type: String

  index({ name: 1 }, { unique: false, name: 'project_type_name', background: true })
end

这是嵌入式文档：

class Project::TypeRule
  include Mongoid::Document
  include Mongoid::Timestamps
  include Mongoid::Paranoia

  embedded_in :type ,:inverse_of => :rules

  TYPES = ["internal_link", "external_link","h1"]

  field :name,          type: String
  field :rule_type,     type: String
  field :value,         type: String
  field :count,         type: Integer
end

这是测试脚本：

require 'rails_helper'

describe Project::Type, :type => :model do
  let(:type) { create(:project_type) }

  it { should be_stored_in :type }

  # Associations
  it { should embed_many(:rules) }

  #Fields
  it { should have_fields(:name).of_type(String) }
  it { should have_fields(:timing).of_type(String) }
  it { should be_timestamped_document }
  it { should be_paranoid_document }

  #Indexes
  it { should have_index_for(name: 1).with_options(unique: false, name: 'project_type_name', background: true) }
end

我已经在Google上搜索了有关该内容的信息，但不幸的是没有任何线索。测试嵌入式文档的正确方法是什么？

您正在测试Type嵌入了许多规则。现在，您应该测试另一面：

describe Project::TypeRule, :type => :model do
  # Associations
  it { should be_embedded_in(:type).as_inverse_of(:rules) }

  # Fields
  it { should have_fields(:name).of_type(String) }
  ...
end
