@version 0.0.0.2


-- | Testing with an in-memory sqlite database using persistent-sqlite
module Test.Syd.Persistent

-- | Get a connection from the pool, run the given action, and then return
--   the connection to the pool.
--   
--   This function performs the given action in a transaction. If an
--   exception occurs during the action, then the transaction is rolled
--   back.
--   
--   Note: This function previously timed out after 2 seconds, but this
--   behavior was buggy and caused more problems than it solved. Since
--   version 2.1.2, it performs no timeout checks.

-- | A flipped version of <a>runSqlPool</a> to run your tests
runPersistentTest :: ConnectionPool -> SqlPersistM a -> IO a

-- | Helper function to run a <a>Migration</a> before/in a test suite that
--   works accross versions of <tt>persistent</tt>.
migrationRunner :: MonadIO m => Migration -> ReaderT SqlBackend m ()

-- | Test that the given migration succeeds, when applied to the current
--   database.
--   
--   This uses two tests:
--   
--   <ol>
--   <li>A golden test for the current migration.</li>
--   <li>A test that first applies the golden migration, and then the
--   current migration, tee see if that fails.</li>
--   </ol>
