How to apply play-evolutions when running tests in play-framework?

You can use the following to apply evolutions before each suite and clean up afterwards:

trait DatabaseSupport extends BeforeAndAfterAll {
  this: Suite with ServerProvider =>

  private lazy val db = app.injector.instanceOf[DBApi]

  override protected def beforeAll(): Unit = {
    super.beforeAll()
    initializeEvolutions(db.database("default"))
  }

  override protected def afterAll(): Unit = {
    cleanupEvolutions(db.database("default"))
    super.afterAll()
  }

  private def initializeEvolutions(database: Database):Unit = {
    Evolutions.cleanupEvolutions(database)
    Evolutions.applyEvolutions(database)
  }

  private def cleanupEvolutions(database: Database):Unit = {
    Evolutions.cleanupEvolutions(database)
  }

}

This is working for me:

class DAOSpec extends PlaySpec with GuiceOneAppPerSuite {

  val dbUrl = sys.env.getOrElse("DATABASE_URL", "postgres://foo:password@localhost:5432/foo")

  val testConfig = Map("db.default.url" -> dbUrl)

  implicit override def fakeApplication() = new GuiceApplicationBuilder().configure(testConfig).build()

  lazy val database = app.injector.instanceOf[Database]
  lazy val dao = app.injector.instanceOf[DAO]

  "create" must {
    "work" in Evolutions.withEvolutions(database) {
      val foo = await(dao.create("foo"))
      foo.id must not be null
    }
  }

}
