Sorry for kind for flooding the post. But I just want to save the time of the one who is looking into the issue. I tried logging the attributes of the engine objects in two cases when I use the default 'plain' strategy and one with 'mock' strategy. It seems engine object created with plain strategy has the attribute 'url' but does not contain the same attribute when we create the object by specifying the mock strategy. That might be the main reason for the exception. Changing the argument from engine.url in database_exist(url_string) to actual uri does not give the error. It seems to be a bug in creation of engine using two strategies or maybe I am missing something.
