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: test_format.rb
    path of file: ./repos/thinreports-generator/test/basic_report/units/core/shape/list
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'test_helper'

class Thinreports::BasicReport::Core::Shape::List::Test
    
  def test_attribute_readers
    format = List::Format.new(LIST_FORMAT)

    assert_equal 255, format.height
    assert_equal true, format.auto_page_break?
    assert_equal true, format.has_header?
    assert_equal true, format.has_page_footer?
    assert_equal false, format.has_footer?
    assert_equal 20.0, format.detail_height
    assert_equal 30.0, format.page_footer_height
    assert_equal 40.0, format.footer_height
    assert_equal 10.0, format.header_height
  end
