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: exif_controller_test.rb
    path of file: ./repos/mushroom-observer/test/controllers/images
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require("test_helper")

# tests of Images controller
module Images
  class EXIFControllerTest < FunctionalTestCase
    def test_exif_gps_hidden
      image = images(:in_situ_ima
    
    def test_exif_parser
      fixture = "#{MO.root}/test/images/geotagged.jpg"
      result, _status = Open3.capture2e("exiftool", fixture)
      unstripped = @controller.test_parse_exif_data(result, false)
      assert_not_empty(unstripped.select do |key, _val|
                         key.match(/latitude|longitude|gps/i)
                       end)
      stripped = @controller.test_parse_exif_data(result, true)
      assert_empty(stripped.select do |key, _val|
                     key.match(/latitude|longitude|gps/i)
                   end)
    end
  end
