Slick 3 session with rollback

Question

I am using slick 3 and I am trying to perform some integration tests with some inserts, some code that uses the db and then I want to rollback all the insert or deletion at the end of the test itself but I cannot find any documentation about it.

Is it possible? How can I achieve it?

Answer 1

You need to use . transactionally around the DBIOAction

eg

val a = (for {
  ns <- coffees.filter(_.name.startsWith("ESPRESSO")).map(_.name).result
  _ <- DBIO.seq(ns.map(n => coffees.filter(_.name === n).delete): _*)
} yield ()).transactionally

val f: Future[Unit] = db.run(a)
