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!

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

49 * How long do we wait after starting gnunet-service-arm
50 * for the core service to be alive?
52 #define ARM_START_WAIT GNUNET_TIME_relative_multiply (GNUNET_TIME_UNIT_SECONDS, 120)
55 * How many times are we willing to try to wait for "scp" or
56 * "gnunet-service-arm" to complete (waitpid) before giving up?
