Hi,

This is in python flask.

I am getting an error in pytest. When I run pytest it says it is working but I get the output below

Output:app\tests\functional\test_routes.py . [ 50%] 
app\tests\unit\test_models.py . [100%]

My code is very similar to this https://gitlab.com/patkennedy79/flask_us...nt_example . When I run pytest -m pytest The code says it works but I get an error. When I put my cursor over

def init_database(test_client):

test client

The error I get is https://imgur.com/a/lDHIPb4

Output:(parameter) make_app_run_in_test_env:  Any
"make_app_run_in_test_env" is not accessed Pylance
No quick fixes available

I named

test_client

instead to

make_app_run_in_test_env.

Also it says pytest is working., but I know it can't be completely working because I added a line from the file https://gitlab.com/patkennedy79/flask_us...t_users.py

def test_invalid_login(test_client, init_database):
    # code not included.
    # The added line is below
    assert b'zzzzzzzzzzzzzzzz' in response.data

and an error doesn't show up. I do not have zzzzzzzzzzzzzzzz anywhere in the html . Any help is appreciated. Also I am using a similar setup to this to run the code.

Also I have 2 tests 1 tests works and the other doesn't, which I mentioned above ,in

Output:
app\tests\functional\test_routes.py . [ 50%] .

app\tests\functional\test_routes.py is the same as tests\functional\test\test_users.py in gitlab ,just with different file names and a few different variables.

Here is my exact code that is causing the error

app/tests/conftest.py

    # username, hashed_password, email
    user = User('ugbuighiug' ,'[email protected]', plaintext_password)
    return user

Thanks.

I managed to fix the code simple error

def init_database(make_app_run_in_test_env):

should just be def init_database() .
