* @page test_pools Memory Pools test

* <h2>Description</h2>
* This module implements the test sequence for the @ref pools subsystem.
*
* <h2>Objective</h2>
* Objective of the test module is to cover 100% of the @ref pools code.
*
* <h2>Preconditions</h2>
* The module requires the following kernel options:
* - @p CH_CFG_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_pools_001
* .
* @file testpools.c
* @brief Memory Pools test source file
* @file testpools.h
* @brief Memory Pools test header file
