如何为等待的工作人员建立规范

Question

我正在尝试为此调用制定规范（一种简单的工作）：

SomeJob.set(wait: 3.seconds).perform_later(messenger.id, EVENT)

我目前拥有的规格：

it 'should call an event for...' do
  expect(SomeJob).to receive(:set).with(wait: 3.seconds).and_call_original
  subject.save
end

它工作正常，但我还想测试它是否在 3 秒后调用 perform_later。正确的做法是什么？

谢谢！

您可以使用 ActiveJob::TestHelper 和 ActiveSupport::Testing::TimeHelpers。

将助手添加到 rails_helper.rb。

  config.include ActiveJob::TestHelper
  config.include ActiveSupport::Testing::TimeHelpers

向规范添加测试。

class Some < ApplicationRecord
  def hello
    SomeJob.set(wait: 3.seconds).perform_later 'Hello!'
  end
end

RSpec.describe Some, type: :model do
  it 'should start job after 3 seconds' do
    time = Time.current
    travel_to(time) do
      assertion = {
        job: SomeJob,
        args: ['Hello!'],
        at: (time + 3.seconds).to_i
      }
      assert_enqueued_with(assertion) { Some.new.hello }
    end
  end
end
