Migrations are used for changing the structure of the database so you
should not need to do this (assuming you are just inserting values in
an existing table as you say). If you enclose your work in a
transaction then if you perform a rollback before completing the
transaction then it will be undone.

Of course I am sure you are not performing your tests connected to a
production database. Things can go wrong when trying this sort of
thing, especially if you are learning about concepts such as
transactions and migrations at the same time.
