+ * @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_CFG_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
