22 * @file testing/testing.c
23 * @brief convenience API for writing testcases for GNUnet
24 * Many testcases need to start and stop gnunetd,
25 * and this library is supposed to make that easier
26 * for TESTCASES. Normal programs should always
27 * use functions from gnunet_{util,arm}_lib.h. This API is
28 * ONLY for writing testcases!

47 * Hack to deal with initial HELLO's being often devoid of addresses.
48 * This hack causes 'process_hello' to ignore HELLOs without addresses.
49 * The correct implementation would continue with 'process_hello' until
50 * the connection could be established...
