Transformers allow you to transform values passed to form steps.

For example a select requires to pass a value /options/1b30f17e-e445-4d28-a30c-dedad95829ab. This one is quite unreadable, but with the help of transformers you are able to write it like this: d:options:someOptionName.

In real-life example it will look similar to:

I fill the "myForm" form with:
  | inputElement    | d:someDictionary:someKey            |
  | textareaElement | g:someGenerator                     |
  | radioElement    | v:someVariableName                  |
  | checkboxElement | standard value                      |

There are 3 types of built-in transformers:


Dictionaries allows you to transform a value A to value B using a simple key->value transformation.

You can run a dictionary transformer by providing dictionary prefix d:, specifying the dictionary name and key that should be used as a value provider. For example:


this example assumes that there is a dictionary that supports name myDictionaryName and it has myDictionarKey key.

You can read about dictionaries in Extending Kakunin section.


Generators allows you to generate a value by using a specified generator.

This can be done by: g:generatorName.

If a generator supports parameters then you can specify them by:


You can read more about generators in Extending Kakunin section.

Variable store

Variable store allows you to fill the form with a value that was saved in previous steps of current running scenario.

This can be done by:
