12 * RedBeanPHP does NOT parse entire queries and it does not
13 * ship with a query builder. However because RedBeanPHP
14 * facilitates mixing-in SQL snippets using methods like
15 * find(), via(), with(), withCondition() and so on...,
16 * it needs to be able to figure out how two query part strings
17 * can be connected to eachother. In particular parts beginning with or
18 * without 'WHERE', 'AND' and 'OR'. This test checks whether the
19 * QueryWriter has the ability to glue together query parts correctly.
20 * The gluer is part of the QueryWriter, however since this narrow
21 * slice of SQL syntax is so generic it's been implemented at Writer
22 * level and all drivers in RedBeanPHP inherit the generic implementation.
23 * At the moment of writing no additional glue methods had to be
26 * @file RedUNIT/Blackhole/Glue.php
27 * @desc Tests query gluer.
