我有一个简单的工作人员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

然后我正在测试这个工人：

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.fake 相关的 Sidekiq 文档！“Sidekiq 不是将作业推送到 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在测试环境中尝试连接 Redis 而不是检查作业数组的大小？

有没有办法Sidekiq::Queue使用Sidekiq::Testing.fake!或我应该嘲笑它？

Sidekiq 的 API 没有测试模式，[它] 会一直打 Redis。
