这是我的情景:

更新AR对象后,它会使用Resque触发一堆后台作业.在我的规格中,我正在嘲笑对Resque#enqueue的调用,其中包含以下内容:

it 'should be published' do
  # I need to setup these mocks in many places where I want to mock a specific call to Resque, otherwise it fails
  Resque.should_receive(:enqueue).with(NotInterestedJob1, anything)
  Resque.should_receive(:enqueue).with(NotInterestedJob2, anything)
  Resque.should_receive(:enqueue).with(NotInterestedJob3, anything)

  # I'm only interested in mocking this Resque call.
  Resque.should_receive(:enqueue).with(PublishJob, anything)
end

正如你所看到的,我需要模拟所有其他调用Resque #enqueue每次我想模拟一个特定的调用,有没有办法只模拟自定义调用并忽略其他调用不同的参数？

提前致谢 ;)

我有一个上传器,我已经实现了#filename方法来获取自定义和唯一的文件名,但在保存文件之前看起来这个方法被忽略了(我上传到带有gem gem的rackspace)

这是上传者:

class MyImageUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick

  ...

  def filename
    if original_filename.present?
      "#{secure_token}.#{file.path.split('.').last.downcase}"
    else
      super
    end
  end

  ...

  private

  def secure_token
    var = :"@#{mounted_as}_secure_token"
    model.instance_variable_get(var) or model.instance_variable_set(var, SecureRandom.uuid)
  end
end

这是控制台中的一个测试(我正在测试一个我认为用自定义#filename方法解决的大文件名的问题):
