Я читаю пример формы с api.drupal.ru Как ее можно отобразить в браузере ?Я как модуль активировал и как просмотреть ?

<?php
function test_form($form_state) {
// Access log settings:
$options = array('1' => t('Enabled'), '0' => t('Disabled'));
$form['access'] = array(
'#type' => 'fieldset',
'#title' => t('Access log settings'),
'#tree' => TRUE,
);
$form['access']['log'] = array(
'#type' => 'radios',
'#title' => t('Log'),
'#default_value' => variable_get('log', 0),
'#options' => $options,
'#description' => t('The log.'),
);
$period = drupal_map_assoc(array(3600, 10800, 21600, 32400, 43200, 86400, 172800, 259200, 604800, 1209600, 2419200, 4838400, 9676800), 'format_interval');
$form['access']['timer'] = array(
'#type' => 'select',
'#title' => t('Discard logs older than'),
'#default_value' => variable_get('timer', 259200),
'#options' => $period,
'#description' => t('The timer.'),
);
// Description
$form['details'] = array(
'#type' => 'fieldset',
'#title' => t('Details'),
'#collapsible' => TRUE,
'#collapsed' => TRUE,
);
$form['details']['description'] = array(
'#type' => 'textarea',
'#title' => t('Describe it'),
'#default_value' => variable_get('description', ''),
'#cols' => 60,
'#rows' => 5,
'#description' => t('Log description.'),
);
$form['details']['admin'] = array(
'#type' => 'checkbox',
'#title' => t('Only admin can view'),
'#default_value' => variable_get('admin', 0),
);
$form['name'] = array(
'#type' => 'textfield',
'#title' => t('Name'),
'#size' => 30,
'#maxlength' => 64,
'#description' => t('Enter the name for this group of settings'),
);
$form['hidden'] = array('#type' => 'value', '#value' => 'is_it_here');
$form['submit'] = array('#type' => 'submit', '#value' => t('Save'));
return $form;
}

function test_page() {
return drupal_get_form('test_form');
}
?>
