+ * <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_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
