Class: behat_form_radio  - X-Ref

Radio input form field.

Extends behat_form_checkbox as the set_value() behaviour
is the same and it behaves closer to a checkbox than to
a text field.

This form field type can be added to forms as any other
moodle form element, but it does not make sense without
a group of radio inputs, so is hard to find it alone and
detect it by behat_field_manager::get_form_field(), where is useful
is when the default behat_form_field class is being used, it
finds a input[type=radio] and it delegates set_value() and
get_value() to behat_form_radio.
