What is wrong with this Flask test code snippet?
client = app.test_client()
response = client.get('/login')
assert response.status == 200
AThe attribute should be response.status_code, not response.status.
BThe test client must be created with FlaskClient() instead.

    The attribute should be response.status_code, not response.status. -> Option A
