Exception while trying to redirect to login in test environment

[mvalik]

When I'm trying to create a test which is calling to the endpoint with the decorator @flask_oidc.require_login I got the following exception:

>       r = client.get(url, follow_redirects=False)

In my local environment, I've replaced: url_for("oidc_auth.login"), to url_for("login"), directly in library and that's worked for me.

Hi! That's surprising, flask-oidc provides a blueprint named oidc_auth and registers it with the app when the extension is instantiated (or when init_app() is called). How is the OpenIDConnect object instantiated? Which version of flask-oidc are you using? Thanks.
