## What strategy is fastest? ## What strategy is fastest?
For the SQL libraries the fastest option will be to use `:transaction` as transactions are simply rolled back. If you can use this strategy you should. However, if you wind up needing to use multiple database connections in your tests (i.e. your tests run in a different proceess than your application) then using this strategy becomes a bit more difficult. You can get around the problem a number of ways. For the SQL libraries the fastest option will be to use `:transaction` as transactions are simply rolled back.
