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