RuntimeError: working outside of application context

I followed the answer from @brenns10 when I ran into a similar problem when using pytest.

I followed the suggestion of putting it into test setup, this works:

import pytest
from src.app import app


@pytest.fixture
def app_context():
    with app.app_context():
        yield


def some_test(app_context):
    # <test code that needs the app context>

Flask has an Application Context, and it seems like you'll need to do something like:

def test_connection(self):
    with app.app_context():
        #test code

You can probably also shove the app.app_context() call into a test setup method as well. Hope this helps.
