Ruby on rails Sidekiq：：测试。假的！不是伪造Sidekiq:：队列

我有一个简单的worker，它正在访问自己队列的大小：

需要“sidekiq/api”

class TestWorker
  include Sidekiq::Worker

  def perform(*args)
    Sidekiq::Queue.new('test').size
  end
end

然后我测试这个工人：

require 'rails_helper'

RSpec.describe TestWorker, type: :worker do
  describe '#perform' do
    it 'executes the job without connecting to Redis in the testing environment' do
      require 'sidekiq/testing'
      Sidekiq::Testing.fake! do
        TestWorker.perform_async
        TestWorker.drain
      end
    end
  end
end

此测试失败，因为它尝试访问redis:

1) TestWorker#perform executes the job without connecting to Redis in the testing environment
     Failure/Error: Sidekiq::Queue.new('test').size

     Redis::CannotConnectError:

根据与Sidekiq:：Testing.false相关的Sidekiq文档！Sidekiq没有将作业推送到Redis，而是将它们推送到您可以访问的作业数组中

为什么

Sidekiq:：Queue.new（'test'）.size

试图连接到Redis，而不是在测试环境中检查作业数组的大小

有没有办法让

Sidekiq:：Queue

与

Sidekiq:：Testing.false一起工作还是我应该模仿它

Sidekiq的API没有测试模式，[它]将始终命中Redis
