22 * @file testing/testing.c
23 * @brief convenience API for writing testcases for GNUnet
24 * Many testcases need to start and stop a peer/service
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 (or internal use of the testbed).
