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: spec_helper.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/spec/mspec/spec
    
    the code of the file until where you have to start completion: RSpec.configure do |config|
 
    
def run_mspec(command, args)
  cwd = Dir.pwd
  command = " #{command}" unless command.start_with?('-')
  cmd = "#{cwd}/bin/mspec#{command} -B spec/fixtures/config.mspec #{args}"
  out = `#{cmd} 2>&1`
  ret = $?
  out = out.sub(/\A\$.+\n/, '') # Remove printed command line
  out = out.sub(RUBY_DESCRIPTION, "RUBY_DESCRIPTION")
  out = out.gsub(/\d+\.\d{6}/, "D.DDDDDD") # Specs total time
  out = out.gsub(/\d{2}:\d{2}:\d{2}/, "00:00:00") # Progress bar time
  out = out.gsub(cwd, "CWD")
  return out, ret
end
