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: tester_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 TesterTest < Minitest::Test
  include Ethereum

  def setup
    @s = Tester::State.new

    
  def test_abi_contract_infterface
    contract_path = File.join CONTRACTS_DIR, 'simple_contract.sol'
    compiler = Tester::Language.get :solidity

    simple_compiled = compiler.compile_file contract_path
    simple_address = @s.evm simple_compiled['Simple']['bin']

    abi_json = JSON.dump simple_compiled['Simple']['abi']
    abi = Tester::ABIContract.new @s, abi_json, simple_address, listen: false, log_listener: nil, default_key: nil
  end
