OK, so it ought to be:
error::sqlalchemy.exc.SAWarning
...instead, but that doesn't work because of
https://bugs.python.org/issue22543, so you need to do it in code. I
have this in my top-level py.test conftest.py:
@pytest.fixture(scope='session', autouse=True)
def sqlalchemywarnings():
"Convert SQLAlchemy warnings to exceptions"
import sqlalchemy.exc
warnings.simplefilter(
'error',
sqlalchemy.exc.SAWarning
)
