Accessing session object during Unit test of Flask application

Question

I know it is possible to create session object using session_transaction() method. However, is there a way to access the current session object which gets created when for example "/" route gets hit? I did from flask import session to access the session but it's empty. Let me know if it is possible. Thanks.

This is what you're looking for. As it says however, you'd have to use the instantiation you create in your with statement.

with app.test_client() as c:
    with c.session_transaction() as sess:
        sess['a_key'] = 'a value'

    # once this is reached the session was stored
    result = app.test_client.get('/a_url')
    # NOT part of the 2nd context

Note that this won't work if you run your test within the scope of the with c.session_transaction() as sess statement, it needs to be run after that block.
