function ReferenceOptionLimitEntityreferenceTestCase::helperTestNodeCreateForm in Reference field option limit 7

Helper to run tests.

This allows us to run the same tests with different field settings.

Parameters

$settings: An array of key settings for the field and instance, with the following properties:

• 'widget': The widget type used by the the field instance. One of either 'options_select' or 'options_buttons'.
• 'cardinality': The cardinality on the field. One of either 1 or FIELD_CARDINALITY_UNLIMITED.
• 'default': The default value on the field instance. An array of values (without the FieldAPI nesting for language and delta). For no default value, an empty array.
• 'empty_behaviour': Whether the limited field shows all options (FALSE) or none (TRUE) when the matching field is initially empty.
