如何使用 rspec 测试 ActiveRecord 模型范围和查询

问题描述 投票:0回答:1

我正在尝试在我的 ActiveRecord

Flight
对象范围(例如
#around_date
)上编写 rspec-rails 测试。这是我写的一个测试:

  let(:flight) { create(:flight) } 
  date = DateTime.new(year=2023, month=12, day=25)

  it 'selects within default date range' do
    flights = Flight.around_date(date.to_s).to_a
    expect flights.to include(flight)
  end

这应该测试

#around_date
作用域将返回使用
Flight
创建的
let
对象。 (工厂创建日期为 12-25-2023)。

这是

#around_date
模型中
Flight
范围的代码:

scope :around_date, ->(date_string, day_interval = 1) {
    if date_string.present?
      date = Date.parse(date_string)

      lower_date = date - day_interval.days
      upper_date = date + day_interval.days
      where(start_datetime: (lower_date..upper_date))
    end
  }

当我运行测试时,我收到以下错误消息:

 Failure/Error: expect flights.to include(created_flights)
 
 NoMethodError:
   undefined method `>=' for #<RSpec::Matchers::BuiltIn::ContainExactly:0x00007fe400279098 @expected=[#<Flight id: 1, departure_airport_id: 2, arrival_airport_id: 1, start_datetime: "2023-12-25 00:00:00.000000000 +0000", duration_minutes: 30, created_at: "2023-12-02 16:51:32.363329000 +0000", updated_at: "2023-12-02 16:51:32.363329000 +0000">]>
 # ./spec/models/flight_spec.rb:11:in `block (4 levels) in <main>'

我不知道这个错误消息的含义,因为相关代码中的任何地方都没有

>=
的情况。

任何关于此错误消息可能意味着什么的想法将不胜感激!

您的测试应该是:

let(:flight) { create(:flight) }  
date = DateTime.new(year=2023, month=12, day=25)

it 'selects within default date range' do   
  flights = Flight.around_date(date.to_s).to_a   
  expect(flights).to include(flight) 
end
