- * @page test_mbox Mailboxes test
- *
- * File: @ref testmbox.c
- *
- * <h2>Description</h2>
- * This module implements the test sequence for the @ref mailboxes subsystem.
- *
- * <h2>Objective</h2>
- * Objective of the test module is to cover 100% of the @ref mailboxes
- * subsystem code.<br>
- * Note that the @ref mailboxes subsystem depends on the @ref semaphores
- * subsystem that has to met its testing objectives as well.
- *
- * <h2>Preconditions</h2>
- * The module requires the following kernel options:
- * - @p CH_USE_MAILBOXES
- * .
- * In case some of the required options are not enabled then some or all tests
- * may be skipped.
- *
- * <h2>Test Cases</h2>
- * - @subpage test_mbox_001
- * .
- * @file testmbox.c
- * @brief Mailboxes test source file
- * @file testmbox.h
- * @brief Mailboxes header file
