/**
* @page test_mbox Mailboxes test
*
* <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 as a necessary step in order to assess its maturity
* level.<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
