问题
I have dropped a MongoDB database called 'test' but when I connect to mongod it shows it in the connection. Please see the code below. Can you please help me understand what is going on? Is this a bug or I am missing something? Why is it that test is not in the list of databases when using show dbs command. Thanks for the help.

Your show dbs output only has one db, local, which is created automatically. If you don't specify a database on startup the mongo shell defaults to test which is why you see "connecting to: test". The database test will not be created until you start inserting data into a collection in it.
