    # This module handles stubbing on the hydra side.
    # It plays well with the block_connection configuration,
    # which raises when you make a request which is not stubbed.

      # Override queue in order to check for matching expecations.
      # When an expecation is found, super is not called. Instead a
      # canned response is assigned to the request.

      # @example Queue the request.
