dodanie i usuniecie wiersza AUTO INCREAMENT

witam
w mojej aplikacji potrzebuje na poczatku dodac do tabeli wiersz gdzie id = auto increament;
Nastepnie bede musial wykonac testy przy uzyciu selenium driver
Po wykonanym tescie musze usunac ostatnio zapamietany, dodany wiersz.

ps. nie wchodzi w gre dodanie sobie wiersza z id=10000 a pozniej usuniecie go na podstawie id=10000, oraz przypadek w ktorym usuniety zostanie najwiekszy id gdyz test moze trwac 20 sekund, a w tym czasie moga zostac dodane rekordy do bazy. Bede bardzo wdzieczny za pomoc

moj log z konsoli poki co wyglada tak
Connected database successfully...
Key returned from 'delete LAST_INSERT_ID()': 21084
PASSED: test
