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