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: test.rb
    path of file: ./repos/oso/docs/examples/add-to-your-application/ruby
    
    the code of the file until where you have to start completion: require 'test-unit'
require 'rac
    
  def test_data_filtering_works
    get "/repos"
    puts last_response.inspect
    # make sure some repo is returned
    assert last_response.body.length > 4
    assert last_response.ok?
  end
