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_integration_resultset.rb
    path of file: ./repos/sqlite3-ruby/test
    
    the code of the file until where you have to start completion: require "helper"

class IntegrationResultSetTestCase < SQLite3::TestCase
  def setup
    @db = SQLite3::Database.new(":memory:")
    @db.transaction do
      @db.execute "create table foo ( a integer primary key, b text )"
      @db.execute "insert into foo ( b ) values ( 'foo' )"
    
  def test_real_translation
    @db.execute("create table foo_real(a real)")
    @db.execute("insert into foo_real values (42)")
    @db.query("select a, sum(a), typeof(a), typeof(sum(a)) from foo_real") do |result|
      result = result.next
      assert_kind_of Float, result[0]
      assert_kind_of Float, result[1]
      assert_kind_of String, result[2]
      assert_kind_of String, result[3]
    end
  end
