import pytest
from reversible_anonymizer import ReversibleAnonymizer
from reversible_anonymizer.exceptions import ServiceNotEnabledError

def test_anonymizer_initialization():
    with pytest.raises(ServiceNotEnabledError):
        ReversibleAnonymizer("invalid-project")

def test_custom_info_types():
    anonymizer = ReversibleAnonymizer(
        "your-project-id",
        info_types=[{"name": "EMAIL_ADDRESS"}],
        check_services=False
    )
    assert anonymizer.info_types == [{"name": "EMAIL_ADDRESS"}]
