Our behat tests should use data generators to create data that is assumed by tests directly in the database.

Using data generators in behat

The main exists step

Given the following "([^"]*)" exist:

If the data generator can be used by passing a single set of data in an array or object then the it can be used in the main behat exists step.

To make a data generator usable in this step you must add a new entry to the \testing\behat\steps\database\datageneration::$datagenerator_map array. It has the following form:

'myexample' => array('example', 'core', 'create_example'),

The array key is the name that will be used to call the data generator in the step. The values of the sub array have the following meanings

Using the data generator will now look like:

Given the following "myexample" exist:

Details about the required and optional fields for the data generator should be added to Writing automatic functional tests for Rogo

In a custom step

Data generators should be loaded using the \testing\datagenerator\loader::get()

To load the user data generator you would use:

\testing\datagenerator\loader::get('users', 'core')
