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: duration_test.rb
    path of file: ./repos/wavefile/test
    
    the code of the file until where you have to start completion: require "minitest/autorun"
require "wavefile"

include WaveFile

class DurationTest < Minitest::Test
  SECONDS_I
    
  def test_equality_less_than_millisecond_difference
    # Although each represents a different amount of time,
    # the difference is less than 1 millisecond, which is
    # the maximum resolution of a Duration. Therefore, they
    # are considered equal.
    duration_1 = Duration.new(500, 44100)
    duration_2 = Duration.new(501, 44100)

    assert_equal(duration_1, duration_2)
  end
