Can Rspec wait for an answer from a ApplicationJob?

I'm calling a method inside a model, from a spec file. However, the method has a background job. How can I set spec to waiting for a response from the background job? Is it possible?

My Rspec File: 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  endend

My Model File: user.rb

class User < ApplicationRecord  def update_last_name!    UpdateLastNameJob.perform_later(self.id,"Test Last Name")  endend

My Background Job Working in reddis: 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  endend
