/* This is a generic test for the following use-case in the ietf-hardware model
 *  - Process #1 starts and uses sr_set_item to set some data in the "/ietf-hardware:hardware/component" subtree
 *  - Process #2 starts and implements sr_oper_get_items_subscribe for the data in the same subtree
 *  - Process #3 should see all of the data.
 *
 *  Processes #1 and #2 are started (and stopped) by ctest wrapper script (sysrepo_test_merge_fixture.sh) and their code can be found in sysrepo_test_merge_daemon.cpp
 *  The wrapper script ŕeturns *after* both processes report that sysrepo is initialised (ie., callback is added in #2, items are set in #1).
 *  This is implemented simply via some checks whether file exists (see the sh file).
