Stefan,

No, they’re both implemented in glib/gmessages.c with no reference to the test system. In fact you might not need to set the fatal handler if you don’t call g_test_init: The first thing it does is set the fatal mask to CRITICAL, ERROR, an WARNING. Normally only CRITICAL is fatal.

For an example that uses g_log_set_handler without g_test_init see https://github.com/Gnucash/gnucash/blob/stable/libgnucash/backend/xml/test/gtest-load-save-files.cpp
