RSpec控制器GET #索引测试返回一个空的ActiveRecord数组而不是我的模型

Question

请原谅我的生锈，第一次接触Rails和这个项目相当长一段时间。

Ruby版本:2.5.0
Rails版本:5.1.7
RSpec Version:3.9.3
FactoryBot Version:6.2.0

这是我的scripts_controller_spec.rb文件与模型创建和问题的测试:

require 'rails_helper'
describe ScriptsController, type: :controller do
userID_1 = User.create!(
email: '[e-mail]',
password: 'useruser',
password_confirmation: 'useruser'
)
script1 = Script.create!(
name: 'YWoodcutter',
skill: 'Woodcutting',
bot_for: 'TRiBot',
game_for: 'Oldschool Runescape 07',
user_id: userID_1.id
)
script1.save

describe "GET #index" do
it "assigns @scripts" do
get :index
p script1
expect(assigns(:scripts)).to eq([script1])
end
end

运行测试时，上面的打印行输出如下所示:

#<脚本id: 1，名称:"YWoodcutter"，技能:"Woodcutting"， bot_for: "TRiBot"， game_for: "Oldschool Runescape 07"， user_id: 1, created_at:"

然而，我得到这个测试失败:

失败:

1. ScriptsController GET #index分配@scripts失败/错误:期望(分配(:脚本))。eq ([script1])

   :[#<脚本id: 1，名称:"YWoodcutter"，技能:"Woodcutting"， bot_for: "TRiBot"， game_for: "Oldschool Runescape 07"，User_id: 1, created_at: "2021-10-19 08:29:43" updated_at: "2021-10-1908:29:43"祝辞]
   有:# & lt; ActiveRecord::关系[]在

   (使用==比较)

我的scripts_controller.rb索引函数看起来像这样:

class ScriptsController < ApplicationController
def index
@scripts = Script.order(:created_at)
end

如果你需要更多的信息，请告诉我，谢谢你的帮助!

Answer 1

我认为Script对象在调用index动作之前没有被创建。因此，您将获得空的ActiveRecord::Relation． 在这种情况下让!应该可以解决你的问题

require 'rails_helper'
describe ScriptsController, type: :controller do
let!(:user_1) do
User.create!(
email: '[e-mail]',
password: 'useruser',
password_confirmation: 'useruser'
)
end
let!(:script1) do
Script.create!(
name: 'YWoodcutter',
skill: 'Woodcutting',
bot_for: 'TRiBot',
game_for: 'Oldschool Runescape 07',
user_id: user_1.id
)
end
describe "GET #index" do
before { get :index }
it "assigns @scripts" do
expect(assigns(:scripts)).to eq([script1])
end
end
end

Answer 2

根据当前的代码，似乎您没有调用所有脚本。

使用

### Controller
@scripts = Script.all.order(:created_at)
### Test
## Should use factories to create the records
let(:user) do 
create(:user, email: '[e-mail]',
password: 'useruser',
password_confirmation: 'useruser') 
end
let(:script) do 
create(:script, name: 'YWoodcutter',
skill: 'Woodcutting',
bot_for: 'TRiBot',
game_for: 'Oldschool Runescape 07',
user: user) 
end

应该修复它。
