In the last chapter we discussed methods of testing problems which can happen only on production server. Lets repeat them:

Method #25: if something unexpected happens check error log first.

Method #26: turn InnoDB Monitor to on to have information about all InnoDB transactions in the error log file.

Method #27: use slow query log to find all slow queries.

Method #28: use MySQL Sandbox for fast and convenient testing of your application using several versions of MySQL server.

Method #29: use part of data when work with queries which return wrong results from huge tables.
