@Li first, thanks a lot for your feedback.

Sure, I can add a check for function existence. 'declare' is a bashism,
I use 'command -v' which we already use for $TST_SETUP and $TST_CLEANUP
in tst_test.h.

	if [ -n "$TST_SETUP" ]; then
		if command -v $TST_SETUP >/dev/null 2>/dev/null; then
			TST_DO_CLEANUP=1
			$TST_SETUP
		else
			tst_brk TBROK "TST_SETUP=$TST_SETUP declared, but function not defined (or cmd not found)"
		fi
	fi

No problem :).

@Cyril any more feedback before I'll send a new version (v4)?

Kind regards,
