RSpec:带有searchkick的模型无效

Question

我不太确定我做得对，但我有两个模型：House和has_one Address。

Address型号具有：

class Address < ApplicationRecord
searchkick
belongs_to :house
end

我正在尝试用类似的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所期望的结果。我的控制器代码如下：

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，但可能是因为我使用FactoryBot，它创建了很多房子，然后当使用index方法时，那里有很多房子，而不仅仅是h吗？

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，非常感谢！

Answer 1

Searchkick文档关于禁用RSpec测试的索引。

您不希望在运行测试时总是在Elasticsearch中更新对象。您只想在明确测试搜索功能(或索引/从索引中删除(时才这样做。为此，您必须禁用searchkick回调，为测试定义自定义标记，并仅为这些测试启用索引。您可能还需要在测试/测试组之后处理清理索引的问题。

@vich的观点也很重要，在请求之后，您当前创建对象的时间太晚了。

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

Answer 2

尝试在before块中创建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

需要注意的几件事：

1. 与let相反，let!会立即被调用(从而在执行索引操作之前创建记录(
2. 添加一个断点(IDE(或使用一个调试器(byebug、pry等(，并将其放在get :index调用之前，以查看已经存在的房屋(如果有的话(
