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).

1675 * should self-terminate by invoking 'GNUNET_SCHEDULER_shutdown'.
1677 * This function is useful if the testcase is for a single service
1678 * and if that service doesn't itself depend on other services.
1680 * @param testdir only the directory name without any path. This is used for
1681 * all service homes; the directory will be created in a temporary
1682 * location depending on the underlying OS
1683 * @param service_name name of the service to run
1684 * @param cfgfilename name of the configuration file to use;
1685 * use NULL to only run with defaults
1686 * @param tm main function of the testcase
1687 * @param tm_cls closure for 'tm'
1688 * @return 0 on success, 1 on error
