You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: expectation.rb
    path of file: ./repos/savon/lib/savon/mock
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require "httpi"

module Savon
  class Mo
    
    def verify_message!
      return if @expected[:message].eql? :any
      unless equals_except_any(@expected[:message], @actual[:message])
        expected_message = "  with this message: #{@expected[:message].inspect}" if @expected[:message]
        expected_message ||= "  with no message."

        actual_message = "  with this message: #{@actual[:message].inspect}" if @actual[:message]
        actual_message ||= "  with no message."

        raise ExpectationError, "Expected a request to the #{@expected[:operation_name].inspect} operation\n#{expected_message}\n" \
        "Received a request to the #{@actual[:operation_name].inspect} operation\n#{actual_message}"
      end
