"""Teste pentru citire_fdb: balanta din Firebird identica cu exportul .xlsx.

Poarta: `balanta` produsa din copia unei baze `CONT_BAZA.FDB` trebuie sa fie
identica (pana la octet) cu cea produsa de `citire_xlsx.py` din exportul de foaie
de calcul, pe firma de joaca, luna 09/2026. Baza originala NU se deschide: se
copiaza intr-un director temporar.

Pe o masina fara SAGA (fara fbclient.dll, baza, driver sau export) testele se
sar, nu esueaza.

Rulare:  py -m unittest discover -s tests -v
