+/**
+ * @file gns/test_gns_twopeer.c
+ * @brief base testcase for testing DHT service with
+ *        two running peers.
+ *
+ * This testcase starts peers using the GNUNET_TESTING_daemons_start
+ * function call.  On peer start, connects to the peers DHT service
+ * by calling GNUNET_DHT_connected.  Once notified about all peers
+ * being started (by the peers_started_callback function), calls
+ * GNUNET_TESTING_connect_topology, which connects the peers in a
+ * "straight line" topology.  On notification that all peers have
+ * been properly connected, calls the do_get function which initiates
+ * a GNUNET_DHT_get from the *second* peer. Once the GNUNET_DHT_get
+ * function starts, runs the do_put function to insert data at the first peer.
+ *   If the GET is successful, schedules finish_testing
+ * to stop the test and shut down peers.  If GET is unsuccessful
+ * after GET_TIMEOUT seconds, prints an error message and shuts down
+ * the peers.
