120 * Convenience method for running a "simple" test on the local system
121 * with a single call from 'main'. Underlay and overlay topology are
122 * configured using the "UNDERLAY" and "OVERLAY" options in the
123 * "[testbed]" section of the configuration (with possible options
124 * given in "UNDERLAY_XXX" and/or "OVERLAY_XXX").
126 * The test is to be terminated using a call to
127 * "GNUNET_SCHEDULER_shutdown". If starting the test fails,
128 * the program is stopped without 'master' ever being run.
130 * NOTE: this function should be called from 'main', NOT from
131 * within a GNUNET_SCHEDULER-loop. This function will initialze
132 * the scheduler loop, the testbed and then pass control to
135 * @param testname name of the testcase (to configure logging, etc.)
136 * @param cfg_filename configuration filename to use
137 * (for testbed, controller and peers)
138 * @param num_peers number of peers to start
139 * @param test_master task to run once the test is ready
140 * @param test_master_cls closure for 'task'.
