Ruby on rails Rspec：测试是否对作业中的对象调用了方法？

如果的结束时间小于今天，我会调用一个方法。出于某种原因，即使我在绑定撬即将中断的时候抛出了绑定撬，并手动调用该方法，但仍然会失败。然而，如果我只是让规范测试自己运行，我仍然会失败

我的工作：

class RemoveOldEventsFromAlgoliaJob < ApplicationJob
  queue_as :default

  def perform

    old_events = Event.where("ended_at < ?", Date.today)
    old_events.each do |e|
      e.remove_from_algolia
    end
  end
end

我的规格测试：

require 'rails_helper'

RSpec.describe RemoveOldEventsFromAlgoliaJob, type: :job do
    it "will remove old events from the index" do
    ActiveJob::Base.queue_adapter = :test
    event = FactoryGirl.create(:event, title: "EXPIRED EVENT", ended_at: 1.day.ago)

    RemoveOldEventsFromAlgoliaJob.perform_now

    expect(event).to receive(:remove_from_algolia)
  end
end

RSpec输出：

Failures:

  1) d will remove old events from the index
     Failure/Error: expect(event).to receive(:remove_from_algolia)

尝试使用

事件

的存根，而不是真正的

事件

模型：

require 'rails_helper'

RSpec.describe RemoveOldEventsFromAlgoliaJob, type: :job do
    it "will remove old events from the index" do
    ActiveJob::Base.queue_adapter = :test
    event = double('event')
    allow(Event).to receive(:where).and_return([event])
    expect(event).to receive(:remove_from_algolia)

    RemoveOldEventsFromAlgoliaJob.perform_now

  end
end

当您手动调用该方法时，测试是通过还是仍然失败？一旦我手动调用它，然后退出

pry

，测试仍然失败。然而，我知道我正处于我想要的循环中，所以我不知道为什么我没有通过。我假设它可以工作，但是测试本身被破坏了。我认为这是测试是否对对象调用方法的正确方法。我以前没有做过RSpec模拟。在尝试您的方法后，您能分析此失败吗？`1） RemoveOldEventsFromAlgoliaJob将从索引中删除旧事件`

失败/错误：e.从\u algolia删除\u

\35;收到意外消息

：使用（无参数）从\u algolia删除\u

调用作业前移动最后一个预期，请参阅更新的代码。你有没有解释为什么这是有效的，但另一种方式却有效？我在这个问题上纠缠了一段时间，还没有找到这个解决方案。RSpec无法“记录”给定对象上发生的事情，除非它是由RSpec自己创建的。我确实质疑这样一个事实，即我并没有真正测试这个作业（因为它只调用比今天更老的事件。相反，我似乎只是在测试我的能力，看看对象是否可以接收该方法）。
