/**
* @page test_dynamic Dynamic APIs test
*
* File: @ref testdyn.c
*
* <h2>Description</h2>
* This module implements the test sequence for the dynamic thread creation
* APIs.
*
* <h2>Objective</h2>
* Objective of the test module is to cover 100% of the dynamic APIs code.
*
* <h2>Preconditions</h2>
* The module requires the following kernel options:
* - @p CH_USE_DYNAMIC
* - @p CH_USE_HEAP
* - @p CH_USE_MEMPOOLS
* .
* In case some of the required options are not enabled then some or all tests
* may be skipped.
*
* <h2>Test Cases</h2>
* - @subpage test_dynamic_001
* - @subpage test_dynamic_002
* - @subpage test_dynamic_003
* .
* @file testdyn.c
* @brief Dynamic thread APIs test source file
* @file testdyn.h
* @brief Dynamic thread APIs test header file
