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

class MSSQLMultipleConnectionsTest < Test::Unit::TestCase

  MSSQL_CONFIG2 = { :adapter  => 'mssq
    
    def self.shutdown
      Database1.connection.execute "DROP TABLE [model1s]"
      Database2.connection.execute "DROP TABLE [model2s]"

      ActiveRecord::Base.clear_active_connections!

      ActiveRecord::Base.configurations.replace OLD_CONFIG
      ActiveRecord::Base.establish_connection MSSQL_CONFIG
      super
    end
