22 * @file include/gnunet_testing_lib-new.h
23 * @brief convenience API for writing testcases for GNUnet;
24 * can start/stop one or more peers on a system;
25 * testing is responsible for managing private keys,
26 * ports and paths; it is a low-level library that
27 * does not support higher-level functions such as
28 * P2P connection, topology management or distributed
29 * testbed maintenance (those are in gnunet_testbed_service.h)
