我有一个简单的工作人员正在访问其自己的队列的大小：

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:
       Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)
