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: rails_fixtures_override_test.rb
    path of file: ./repos/test_data/example/test/integration
    
    the code of the file until where you have to start completion: require "test_helper"

TestData.prevent_rails_fixtures_from_loading_automatically!

class FixtureFreeTestData < ActiveSupport::
    
  def test_doing_it_wrong
    error = assert_raises(TestData::Error) do
      TestData.uses_rails_fixtures(ActiveRecord::Base)
    end
    assert_match "'TestData.uses_rails_fixtures(self)' must be passed a test instance that has had ActiveRecord::TestFixtures mixed-in (e.g. `TestData.uses_rails_fixtures(self)` in an ActiveSupport::TestCase `setup` block), but the provided argument does not respond to 'setup_fixtures'", error.message
  end
