Question

我正在尝试测试在创建工厂后是否存在数组中的项目。

规格/模型/ thing_spec.rb

require 'rails_helper'

RSpec.describe Thing, :type => :model do

  let(:thing) { Array.new(3) {FactoryGirl.create(:thing) } }

  it "should sort the items in order" do
    expect(thing).to include(ordering:1, ordering:2, ordering:3)
  end
end

规格/工厂/ things.rb

FactoryGirl.define do
  factory :thing, :class => 'Thing' do
    name "item_name"
    sequence(:ordering)
  end
end

以下是我收到的结果。

结果

  1) Things should be sorted in order
     Failure/Error: expect(thing).to include(ordering:1, ordering:2, ordering:3)
   expected [#<Thing id: 1, name: "item_name", create_date: "2014-11-07 04:18:17", modified_date: "2014-11-14 04:18:17", ordering: 1>, #<Thing id: 2, name: "item_name", create_date: "2014-11-07 04:18:17", modified_date: "2014-11-14 04:18:17", ordering: 2>, #<Thing id: 3, name: "item_name", create_date: "2014-11-07 04:18:17", modified_date: "2014-11-14 04:18:17", ordering: 3>] to include {:ordering => 2}

Answer 1

你不能这样做。您必须像这样单独检查每条记录

it "should sort the items in order" do
  expect(thing[0].ordering).to eq(1)
  expect(thing[1].ordering).to eq(2)
  expect(thing[2].ordering).to eq(3)
end

或者做这样的事情：

it "should sort the items in order" do
  expect(thing.map(&:ordering)).to eq([1, 2, 3])
end

您只能使用include来检查数组是否包含整个元素，如下所示：

expect(thing).to include(thing[0])

测试FactoryGirl结果
