|
|
* <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_CFG_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
