function design_test_menu

Implements hook_menu().

This implementation turns every subdirectory of this module into a category that is exposed as a menu link. Each subdirectory contains include files that consist of a callback function that maps to the semantics of the category. The following categories are supported:

• form: Used for Form API element tests.
• page: Used for theme function tests.

For example, given an include file:

./page/list-operations.inc

A menu router item with the path 'design_test/page/list-operations' will be auto-generated. Upon access, the function design_test_page_list_operations() will be called.

The 'form' category behaves identically; e.g., for an include file './form/details.inc' a menu item for the path 'design_test/form/details' is created and the form constructor function design_test_form_details() will be called.

Each resulting test page is enhanced with local actions that allow to quickly switch between enabled themes for verifying the expected output.
