Once you installed that handler, you can figure if it's called
while a unit test is run. Maybe I don't exactly understand the
problem, but it looks like you are looking for something like:

function_to_test (args)
  g_return_if_fail (precondition);


gboolean test_failed = FALSE;

unit_test_log_func (const gchar   *log_domain,
                    GLogLevelFlags log_level,
                    const gchar   *message,
                    gpointer       user_data)
  print_message ();

  test_failed = TRUE;

do_unit_tests ()
  guint handler_id;

  handler_id = g_log_set_handler ("my_domain", G_LOG_LEVEL_CRITICAL,
                                  unit_test_log_func, NULL);

  test_failes = FALSE;

  function_to_test (wrong_args);

  if (test_failed)
    g_printerr ("eek, the test failed on params: %s", wrong_args);
