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: wiki_push_service_spec.rb
    path of file: ./repos/gitlabhq/spec/services/git
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'spec_helper'

RSpec.describe Git::WikiPushService, services: true, feature_category: :wiki do
  inc
    
        def run_service
          wiki_page = create(:wiki_page, wiki: wiki, title: "#{binary_title} 'foo'")

          process_changes do
            # Test that new_path is converted to UTF-8
            create(:wiki_page, wiki: wiki, title: binary_title)

            # Test that old_path is also is converted to UTF-8
            update_page(wiki_page.title, 'foo')
          end
        end
