Processing test

From Open Food Facts wiki

< Processing Taxonomy

All tests follow the same structure. There is one test set per language. For each process adjective there is a separate test. And a test consists of a string and the required results (ingredient and process).

Template

The template for processing adjectives tests:

  [ { 

Define the language for which the tests are applicable.

  lc => "en",

Define in the ingredients_text the original ingredients that must be tested. These should have the format process ingredient, ingredient process, or whatever is applicable for that language.

  ingredients_text => "raw milk, sliced tomatoes, garlic powder, powdered eggplant, courgette powder" },

The ingredients_text raw milk, should result in the ingredient with id en: raw milk. The adjective is ignored.

  [ {
      'id' => 'en:raw-milk',
      'text' => 'raw milk'
    },

The ingredients_text sliced tomatoes, should result in the ingredient with id en:tomato and processing en:sliced.

    {
      'id' => 'en:tomato',

The id represents the parent key of sliced tomatoes in the ingredients taxonomy.

      'processing' => 'en:sliced',

The processing is the key of sliced in the processing taxonomy.

      'text' => 'tomatoes'

The text is parent key of the entry sliced tomatoes in the ingredients taxonomy ????

    },
    {
      'id' => 'en:garlic-powder',
      'text' => 'garlic powder'
    },
 {
   'id' => 'en:aubergine',
   'processing' => 'en:powdered',
   'text' => 'eggplant'
 },
 {
   'id' => 'en:courgette',
   'processing' => 'en:powdered',
   'text' => 'courgette'
  }
  ] ]

Error message

An error message for the text field might be:

  #   Failed test at t/ingredients_processing.t line 143.
  #     Structures begin differing at:
  #          $got->[3]{text} = 'gehakte tomaten'
  #     $expected->[3]{text} = 'tomaten'

This should be read as: replace gehakte tomaten with tomaten in the test

To test the ingredient gemalen kokos, we get:

#   Failed test at ../t/ingredients_processing.t line 143.
#     Structures begin differing at:
#          $got->[3]{processing} = Does not exist
#     $expected->[3]{processing} = 'en:ground'

The test failed here as gemalen kokos is already in the ingredients taxonomy. We need to test with an ingredient that is not in the ingredients taxonomy. "gemalen XYZ" should not be in the ingredients taxonomy, but "XYZ" should be. (otherwise we won't match)

So the got is what you specified in the test and the expected is what the app calculated.
