ruby-on-rails - RSpec:带有 searchkick 的无效模型

Question

我不太确定我做对了，但我有两个模型:House has_one Address。

地址模型有:

class Address < ApplicationRecord
  searchkick
  belongs_to :house
end

我正尝试像这样用 RSpec 测试我的 house_controller

RSpec.describe HousesController do
 context 'GET #index' do
 before { get :index }
 it     { is_expected.to render_template('index') }

 it 'assigns @houses' do
  h = create(:house)
  expect(assigns(:houses).results).to eq([h])
end
...

然而，我总是得到一个不是我期望的结果。我的 Controller 的代码如下:

def index
 if params[:term].present?
  @houses = House.search(params[:term])
 else
  @houses = House.search('*')
 end
end

我不确定我是否理解它，但可能是因为我正在使用 FactoryBot，它正在创建很多房屋，然后在进入 index 时code> 方法，那里有一堆房子，而且不仅是 h?

这是我的失败:

我现在开始使用 RSpec，我真的花了很多时间和精力来掌握它，在此先感谢您!

Searchkick docs关于禁用 RSpec 测试的索引。

您不希望在运行测试时总是更新 Elasticsearch 中的对象。只有当您明确测试搜索功能(或从索引中建立索引/删除)时，您才想这样做。为此，您必须禁用 searchkick 回调，为您的测试定义一个自定义标签，并仅为这些测试启用索引。您可能还需要在测试/测试组之后清理索引。

@vich 的观点也很重要，您目前在请求之后创建对象为时已晚。

我会将您的设置更改为:

context 'GET #index', :search do
  let!(:house) { create(:house) }
  before { get :index }

  it 'assigns @houses' do
    expect(assigns(:houses).results).to eq([house])
  end
end
