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: big_decimal_test.rb
    path of file: ./repos/universalid/test/universalid/message_pack_types/scalars
    
    the code of the file until where you have to start completion: # frozen_string_liter
    
  def test_global_id
    expected = BigDecimal("9876543210.0123456789")
    gid = URI::UID.build(expected).to_gid_param
    uid = URI::UID.from_gid(gid)
    actual = uid.decode

    assert_equal expected, actual
  end
