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。

Address 模型有：

class Address < ApplicationRecord
  searchkick
  belongs_to :house
end

我正在尝试用 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
...

尽管如此，我总是得到一个不是我期望的结果。我的控制器的代码如下：

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，但可能是因为我使用 FactoryBot，它正在创建很多房屋，然后在进入 index 方法时，那里有一堆房子，而且不只是 h?

这是我的失败：

我现在从 RSpec 开始，我真的花了很多时间和精力来掌握它，非常感谢！

Answer 1

尝试在前面的块中创建您的 house：

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

  it { is_expected.to render_template('index') }

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

有几点需要注意：

与 let 相反，let! 被立即调用（因此在索引操作被命中之前创建您的记录）
添加断点（IDE）或使用调试器（byebug、pry 等）并将其放在 get :index 调用之前以查看已经存在的房屋（如果有）。

Answer 2

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 indexing/deleting 来自索引）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 test/groups 测试后清理索引。

@vich 的观点也很重要，您目前创建对象的时间太晚，在请求之后。

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
