* <h2>Objective</h2>
* Objective of the test module is to cover 100% of the @ref messages
* subsystem code.
*
* <h2>Preconditions</h2>
* The module requires the following kernel options:
* - @p CH_CFG_USE_MESSAGES
* .
* In case some of the required options are not enabled then some or all tests
* may be skipped.
*
* <h2>Test Cases</h2>
* - @subpage test_msg_001
