使用FactoryGirl构建json存根 [英] Building a json stub using FactoryGirl

问题描述

我试图使用工厂来构建json，但是当我尝试build时它是空的.

I am try to build a json using a factory, but when i try to build it's empty.

下面是Factory类.

require 'faker'

FactoryGirl.define do 
    factory :account do |f|
        f.name {Faker::Name.name}
        f.description {Faker::Name.description}     
    end

    factory :accjson, class:Hash do
        "@type" "accountResource"
        "createdAt" "2014-08-07T14:31:58"
        "createdBy" "2"        
        "disabled"  "false"        
    end 
end

下面是我要构建的方式.

Below is how i am trying to build.

hashed_response = FactoryGirl.build(:accjson)        
expect(account.to_json).to eq(hashed_response.to_json);

但是我的hashed_response似乎总是空的object.

But my hashed_response always seems to be empty object.

推荐答案

使用FactoryGirl创建json就像使用航天飞机将菠萝去皮一样.尽力而为后，您将执行此操作，但这并不是为它创建航天飞机的目的.

Using FactoryGirl to create a json is like using space shuttle to peel the pineapple. You'll do that after you try hard enough, but it is not what shuttle has been created for.

如果要在测试中重用此哈希结构，请将其存储在yaml文件中，并创建一些帮助程序方法以读取它(可以将其放置在spec/spec_helpers中).

If you are reusing this hash structure in your test, store it within yaml file and create some helper methods to read it (you can place them within spec/spec_helpers).

FactoryGirl正在使用method_missing魔术来分配值.在您的代码中，您没有尝试执行任何方法，因为您只是在列出字符串，因此不会触发method_missing魔术.

FactoryGirl is using method_missing magic to assign values. In your code, you are not trying to execute any methods, as you are just listing strings, so the method_missing magic is not triggered.

为了完整起见，可以使用FG来做到这一点，但这不是很漂亮:

For completeness, there is a way to do this with FG, however is not very pretty:

factory :accjson, class: OpenStruct do
  send :'@type', "accountResource"
  createdAt "2014-08-07T14:31:58"
  createdBy "2"        
  disabled  "false"        
end

hashed_response = FactoryGirl.build(:accjson).marshal_dump.to_json
