How to apply evolutions to test database from DatabaseConfigProvider

I want to test dao (play 2.6.21, play-slick 3.0.3):

@Singleton
class MyDao @Inject()(@NamedDatabase("default") protected val dbConfigProvider: DatabaseConfigProvider)
                             (implicit val sc: ExecutionContext)
  extends HasDatabaseConfigProvider[JdbcProfile] {
  ...

}

I place database config for test database in test resources:

slick.dbs.default {
  profile = "slick.jdbc.PostgresProfile$"
  endpoint = "localhost:12345"
  schema = "my_test_schemma"

  db {
    driver = "org.postgresql.Driver"
    url = "jdbc:postgresql://"${slick.dbs.default.endpoint}"/"${slick.dbs.default.schema}""
  }
}

In test, I want apply evolutions:

class MyDaoSpec extends FlatSpec with GuiceFakeApplicationFactory {

  implicit lazy val app: Application = fakeApplication()

  "dao" should "something" in {

    val conf = app.injector.instanceOf[DatabaseConfigProvider]
    val db = app.injector.instanceOf[Database]
    Evolutions.applyEvolutions(db)

    val dao = app.injector.instanceOf[MyDao]
    //tests...

  }

}

But it give me error:

Guice configuration errors for instanceOf[Database]:

1) No implementation for play.api.db.Database was bound. while locating play.api.db.Database

So how I can access database and apply evolution to it?

I found, that I need use EvolutionComponents, but dont understand how use it

My mistake was, that I add following dependencies:

libraryDependencies ++= Seq(evolutions, jdbc)

But correct was:

"com.typesafe.play" %% "play-slick-evolutions" % "3.0.3",

There are no special steps for test, just in config:

play.evolutions.enabled = true
play.evolutions.autoApply = true
