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: schema_dump_test.rb
    path of file: ./repos/activerecord-jdbc-adapter/test/db/hsqldb
    
    the code of the file until where you have to start completion: require 'db/hsqldb'
require 'schema_dump'

class HSQLDBSchemaDumpTest < Test::Unit::TestCase
  include 
    
  def test_schema_dump_keeps_id_column_when_id_is_false_and_id_column_added
    output = standard_dump
    match = output.match(%r{create_table "string_ids"(.*)do.*\n(.*)\n})
    assert_not_nil(match, "string_ids table not found")
    assert_match %r((:id => false)|(id: false)), match[1], "no table id not preserved"
    assert_match %r{t.string[[:space:]]+"id",[[:space:]]+limit:[[:space:]]+255,[[:space:]]+null:[[:space:]]+false$}, match[2], "non-primary key id column not preserved"
  end
