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: session.rb
    path of file: ./repos/hyper-react/lib/react/test
    
    the code of the file until where you have to start completion: module React
  module Test
    class Session
      DSL_METHODS = %i[mount instance update_params html].freeze

      def mount(component_klass, params = {})
        @element = React.create_element(component_klass, params)
        instance
      end

      def
    
      def html
        html = `#@container.innerHTML`
        %x{
            var REGEX_REMOVE_ROOT_IDS = /\s?data-reactroot="[^"]*"/g;
            var REGEX_REMOVE_IDS = /\s?data-reactid="[^"]+"/g;
            html = html.replace(REGEX_REMOVE_ROOT_IDS, '');
            html = html.replace(REGEX_REMOVE_IDS, '');
        }
        return html
      end
