Sequential Scalatest problem in Play 2.4:

[Dmitry Ivanov]

Hi!

Now I update my application to Play 2.4 and Slick 3.0. I have amount of tests that splitted into several Spec files. For now the tests start and work correctly only for first Spec. For second and furter ech test produce an error like next:

Task slick.backend.DatabaseComponent$DatabaseDef$$anon$2@24811ba9 rejected from java.util.concurrent.ThreadPoolExecutor@da0ebb1[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 5046].

Full error stack:

Task slick.backend.DatabaseComponent$DatabaseDef$$anon$2@24811ba9 rejected from java.util.concurrent.ThreadPoolExecutor@da0ebb1[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 5046]

Also header of PlaySpec:

  with OptionValues

  with HasDatabaseConfig[JdbcProfile]

  with ActivityDatabaseModule {

  protected lazy val dbConfig = DatabaseConfigProvider.get[JdbcProfile](Play.current)

  import driver.api._

........................

Also headers of first Spec (which works correctly):

package controllers

import slick.driver.PostgresDriver.api._

import fixture.PlaySpec

import play.api.db.slick._

import play.api.i18n.Messages

import play.api.i18n.Messages.Implicits._

import scala.concurrent.ExecutionContext.Implicits.global

class SchoolAdminContactSpec extends PlaySpec {

  "School Admin Contact Controller" should {

    "respond to login and GET activities list for contact by SchoolAdmin" in 

........

and header of second Spec (which fails with mentioned error):

package controllers

import fixture.PlaySpec

import play.api.Play

import play.api.db.slick.DatabaseConfigProvider

import play.api.test.FakeRequest

import play.api.test.Helpers._

import slick.driver.JdbcProfile

import scala.language.implicitConversions

class SchoolAdminControllerSpec extends PlaySpec {

  override lazy val dbConfig = DatabaseConfigProvider.get[JdbcProfile](Play.current)

  "School Admin Controller" should {

    "respond to admin action for logged admin of main center" in {

.......

Thanks for any advise!

I came across the same issue and in my case, the above answers did not work out.
My Solution -

    implicit val app = new FakeApplication(additionalConfiguration = inMemoryDatabase())
    Play.start(app)

Add above code in your first test case and don't add Play.stop(app). As all the test cases are already refering the first application, it should not be terminated. This worked for me.

Sumit!
Thanks for you help!
Sorry, but I can't check your solution now.
