/**
 * UUID
 *
 * Tests whether we can use UUIDs with MySQL/MariaDB, to this
 * end we use a reference implementation of a UUID MySQL Writer:
 * UUIDWriterMySQL, however this class is not part of the code base,
 * it should be considered a reference or example implementation.
 * These tests focus on whether UUIDs in general do not cause any
 * unexpected issues.
 *
 * @file    RedUNIT/Mysql/Uuid.php
 * @desc    Tests read support for UUID tables.
