/**
* @page test_queues I/O Queues test
*
* File: @ref testqueues.c
*
* <h2>Description</h2>
* This module implements the test sequence for the @ref io_queues subsystem.
* The tests are performed by inserting and removing data from queues and by
* checking both the queues status and the correct sequence of the extracted
* data.
*
* <h2>Objective</h2>
* Objective of the test module is to cover 100% of the @ref io_queues code.<br>
* Note that the @ref io_queues 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_QUEUES (and dependent options)
* .
* In case some of the required options are not enabled then some or all tests
* may be skipped.
*
* <h2>Test Cases</h2>
* - @subpage test_queues_001
* - @subpage test_queues_002
* .
* @file testqueues.c
* @brief I/O Queues test source file
* @file testqueues.h
* @brief I/O Queues test header file
