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: cli_helpers.rb
    path of file: ./repos/appsignal-ruby/spec/support/helpers
    
    the code of the file until where you have to start completion: require "appsignal/cli/helpers"

module CLIHelpers
  def cli
    Appsignal::CLI
  end

  def run_cli(command, options = {})
    
  def format_cli_arguments_and_options(command, options = {})
    [*command].tap do |o|
      options.each do |key, value|
        o << (value.nil? ? "--#{key}" : "--#{key}=#{value}")
      end
    end
  end
