ruby-on-rails - Rspec 可以等待 ApplicationJob 的回答吗？

Question

我正在从规范文件中调用模型内部的方法。但是，该方法有一个后台作业。如何将规范设置为等待后台作业的响应？可能吗？

我的 Rspec 文件:user_spec.rb

require 'rails_helper'
RSpec.describe User, type: :model do
  let(:user) { user.create(name: "Test User Name",last_name: "") }
  describe "existing user instance" do
    it "fetch last name" do
      user.update_last_name!
      expect(user.last_name).to eq("Test Last Name")
    end
  end
end

我的模型文件:user.rb

class User < ApplicationRecord

  def update_last_name!
    UpdateLastNameJob.perform_later(self.id,"Test Last Name")
  end

end

我在 reddis 中的后台工作:update_last_name_job.rb

class UpdateLastNameJob < ApplicationJob
  @queue = :default
  def perform(user_id,last_name)
    @user = User.find(user_id)
    @user.last_name = last_name
    @user.save
  end
end

我是这样解决的:

require 'rails_helper'
RSpec.describe User, type: :model do

  include ActiveJob::TestHelper

  let(:user) { user.create(name: "Test User Name",last_name: "") }


  describe "existing user instance" do
    it "fetch last name" do
      user.update_last_name!
      # update_last_name! is calling a background job, so the result will not be ready yet.
      expect(user.last_name).to eq("")
      # This line is goint to execute the backgound job
      perform_enqueued_jobs
      # Models reload with new data
      user.reload
      # Will work!
      expect(user.last_name).to eq("Test Last Name")
    end
  end
end
