Replication successful but slave skips certain queries

I am testing a MySQL master-slave replication. Here is the master my.cnf:

log-bin=/var/log/mysql/mysql-bin.log
server-id=1
innodb_flush_log_at_trx_commit=1
sync_binlog=1

Here is slave my.cnf:

server-id=3
log-bin=/var/log/mysql/mysql-bin.log
relay-log=/var/log/mysql/slave-relay.log
relay-log-index=/var/log/mysql/slave-relay-log.index
log-slave-updates=1
replicate-wild-do-table = ads.%
replicate-ignore-db = mysql
replicate-ignore-db = test

Everything works fine but if I execute something like this on master, it won't replicate to slave.

use test;
INSERT INTO ads.users ( id , username ) VALUES ( 19, 'tyy' );

If I omit use test, the replication is successful.

I would like to skip test db from replication but also need to avoid the above mentioned issue. I have searched a number of posts but couldn't find a solution. Am I missing anything simple?
