+ * The database group has as a side effect that temporal database tables are created. This makes
+ * it possible to test without poisoning a production database.
+ * @group Database
+ *
+ * Some of the tests takes more time, and needs therefor longer time before they can be aborted
+ * as non-functional. The reason why tests are aborted is assumed to be set up of temporal databases
+ * that hold the first tests in a pending state awaiting access to the database.
