Good afternoon, I am developing some unit tests for my Flask application. It is my first time trying to develop unit tests for a Flask app, but I am currently getting this error when trying to test GET requests.
def testTagCategories():
> response = client.get("/forum")
E AttributeError: 'function' object has no attribute 'get'
I have been struggling to find what the problem is, as I have followed all the steps required in the Flask documentation. Here is the code.
@pytest.fixture(scope='session')
def test_client():
flask_app = app()
testing_client = flask_app.test_client()
ctx = flask_app.app_context()
ctx.push()
yield testing_client
ctx.pop()
@pytest.fixture()
def client(app):
return app.test_client()
@pytest.fixture()
def runner(app):
return app.test_cli_runner()
Finally, this is one of the functions where I get the error. Thanks in advance.
def test_access():
response = client.get("/")
assert (response.status_code == 200)
I'm also learning to unit test a flask controller so take my answer with a pinch of salt.
But in the failing code (like below) there appears to be no client instance and thus you cannot call the get method.
def test_access():
response = client.get("/")
assert (response.status_code == 200)
I'm sure there is a nicer way of doing it by having the client created before every test fixture (that's how I would do it in another language I'm more familiar with like C# with setup / teardown before each test).
But something like this works for me:
from app import application
def test_access():
client = application.test_client()
response = client.get('/')
assert response.status_code == 200
html = response.data.decode()
assert 'xxx' in html
in my app directory there is an __init__.py with application = Flask(__name__) in it. That's what from app import application is importing.
Would love to hear a better solution from someone though.
Edit: On the function that is causing an error, trying changing the signature to the following:
def test_access(client):
