测试Sidekiq收到正确的延迟工作

Question

在我的用户模型中,我正在调用一个延迟方法:

class User < ActiveRecord::Base
  def self.import_items
    ...
    User.delay.keep_only_user_cars(1) # "1" is just for testing
  end
end

而我正试图像这样测试它(使用rspec-sidekiq gem):

expect(Sidekiq::Extensions::DelayedClass).to have_enqueued_job("keep_only_user_cars", 1)     

这就是我得到的:

Failure/Error: expect(Sidekiq::Extensions::DelayedClass).to have_enqueued_job("keep_only_user_cars", 1)
  expected to have an enqueued Sidekiq::Extensions::DelayedClass job with arguments ["keep_only_user_cars", 1] but none found
  found: [["---\n- !ruby/class 'User'\n- :keep_only_user_cars\n- - 1\n"]]

哪个基本上有效,只是有点不同的格式.

如何修复此测试以确保Sidekiq正好使用此属性接收此方法？

根据文档,延迟扩展以redis发送整个对象,而不仅仅是值.如果要测试该对象,则需要使用YAML.dump(object):

expected = YAML.dump([User,:keep_only_user_cars,1])
expect(Sidekiq::Extensions::DelayedClass).to have_enqueued_job(expected)
