python - Why would a fixture reference not be able to access a table it created in a unit test?

Question

So I attempted to to create a dynamodb table to run my tests with a pytest fixture like so:

@pytest.fixture
def db_resource():
    db_resource = boto3.resource('dynamodb')
    table = db_resource.create_table(
       ...

    return db_resource

Then I passed it into my test like so:

@mock_dynamodb2
def test_my_code(db_resource):
   other_func(db_resource)

This throws an error saying the table I just created does not exist (this is the first time I've tried doing it this way). However if I change it to a function that generates the table it works fine.

@mock_dynamodb2
def _create_table():
   db_resource = boto3.resource('dynamodb')
    table = db_resource.create_table(
       ...

   return db_resource

and call it in my unit test function...

@mock_dynamodb2
def test_my_code():
    db_resource = _create_table()
    other_func(db_resource)

This works fine. What am I missing?
