Hi, there
Could you include a SQLAlchemy example in the documentation? I'm using the following code but it doesn't work:

import pytest

from projeto import create_app, db as _db


@pytest.fixture(scope='session')
def app():
    app = create_app('testing')
    return app


@pytest.fixture(scope='session')
def db(app, request):
    _db.app = app
    _db.create_all()
    yield _db
    _db.drop_all()


@pytest.yield_fixture(scope='function')
def session(db):
    connection = db.engine.connect()
    transaction = connection.begin()

    options = dict(bind=connection)
    session = db.create_scoped_session(options=options)

    db.session = session

    yield session

    transaction.rollback()
    connection.close()
    session.remove()

This is the error that I get:

app = <Flask 'projeto'>, request = <SubRequest 'db' for <Function 'test_login_page'>>

    @pytest.fixture(scope='session')
    def db(app, request):
       _db.app = app
       _db.create_all()
       yield _db
 >       _db.drop_all()
