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: account_test.rb
    path of file: ./repos/ruby-ethereum/test
    
    the code of the file until where you have to start completion: # -*- encoding : ascii-8bit -*-

require 'test_helper'

class AccountTest < Minitest::Test
  include Ethereum

  def test_initialize_with_balance
    db = DB::
    
  def test_initialize_with_balance
    db = DB::EphemDB.new
    acct = Account.new 2, 99994000000, Trie::BLANK_ROOT, Utils.keccak256(Constant::BYTE_EMPTY), db

    assert_equal 2, acct.nonce
    assert_equal 99994000000, acct.balance
    assert_equal 2, Utils.big_endian_to_int(RLP.decode(RLP.encode(acct))[0])
    assert_equal 99994000000, Utils.big_endian_to_int(RLP.decode(RLP.encode(acct))[1])
  end
