    ##
    # The Sidekiq testing infrastructure overrides perform_async
    # so that it does not actually touch the network.  Instead it
    # stores the asynchronous jobs in a per-class array so that
    # their presence/absence can be asserted by your tests.
    #
    # This is similar to ActionMailer's :test delivery_method and its
    # ActionMailer::Base.deliveries array.
    #
    # Example:
    #
    #   require 'sidekiq/testing'
    #
    #   assert_equal 0, HardWorker.jobs.size
    #   HardWorker.perform_async(:something)
    #   assert_equal 1, HardWorker.jobs.size
    #   assert_equal :something, HardWorker.jobs[0]['args'][0]
    #
    #   assert_equal 0, Sidekiq::Extensions::DelayedMailer.jobs.size
    #   MyMailer.delay.send_welcome_email('foo@example.com')
    #   assert_equal 1, Sidekiq::Extensions::DelayedMailer.jobs.size
    #
    # You can also clear and drain all workers' jobs:
    #
    #   assert_equal 0, Sidekiq::Extensions::DelayedMailer.jobs.size
    #   assert_equal 0, Sidekiq::Extensions::DelayedModel.jobs.size
    #
    #   MyMailer.delay.send_welcome_email('foo@example.com')
    #   MyModel.delay.do_something_hard
    #
    #   assert_equal 1, Sidekiq::Extensions::DelayedMailer.jobs.size
    #   assert_equal 1, Sidekiq::Extensions::DelayedModel.jobs.size
    #
    #   Sidekiq::Worker.clear_all # or .drain_all
    #
    #   assert_equal 0, Sidekiq::Extensions::DelayedMailer.jobs.size
    #   assert_equal 0, Sidekiq::Extensions::DelayedModel.jobs.size
    #
    # This can be useful to make sure jobs don't linger between tests:
    #
    #   RSpec.configure do |config|
    #     config.before(:each) do
    #       Sidekiq::Worker.clear_all
    #     end
    #   end
    #
    # or for acceptance testing, i.e. with cucumber:
    #
    #   AfterStep do
    #     Sidekiq::Worker.drain_all
    #   end
    #
    #   When I sign up as "foo@example.com"
    #   Then I should receive a welcome email to "foo@example.com"
    #
