Description

* 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. * *

Objective

* Objective of the test module is to cover 100% of the @ref io_queues code.
* Note that the @ref io_queues subsystem depends on the @ref semaphores * subsystem that has to met its testing objectives as well. * *

Preconditions

* 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. * *

Test Cases

* - @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 */ #if CH_USE_QUEUES #define TEST_QUEUES_SIZE 4 static void notify(void) {} /* * Note, the static initializers are not really required because the * variables are explicitly initialized in each test case.
