No implementation for play.api.db.slick.DatabaseConfigProvider when trying to create an integration test for a Controller

[Felipe Gutierrez]

Hi,

I am trying since 2 days ago create an integration test for my routes using Play framework. I could create on for the HomeController that doesn't have any parameter on the constructor. Now I have my second Controller: RackController

import javax.inject._

class RackController @Inject()(cc: ControllerComponents, rackRepository: RackRepository, gpuRepository: GpuRepository) extends AbstractController(cc) with I18nSupport {

and I created this integration test:

import models.{GpuRepository, RackRepository}
import org.scalatestplus.play._
import org.scalatestplus.play.guice._
import play.api.db.evolutions.Evolutions
import play.api.db.{Database, Databases}
import play.api.inject.bind
import play.api.inject.guice.GuiceInjectorBuilder
import play.api.test.Helpers._
import play.api.test._


class RackControllerSpec extends PlaySpec with GuiceOneAppPerTest with Injecting {


  val database = Databases(
    driver = "org.sqlite.JDBC",
    url = "jdbc:sqlite:development.db",
    name = "default",
    config = Map(
      "username" -> "",
      "password" -> ""
    )
  )
  val guice = new GuiceInjectorBuilder()
    .overrides(bind[Database].toInstance(database))
    .injector()
  val rack = guice.instanceOf[RackRepository]
  val gpu = guice.instanceOf[GpuRepository]


  def beforeAll() = Evolutions.applyEvolutions(database)


  def afterAll() = {
    // Evolutions.cleanupEvolutions(database)
    database.shutdown()
  }


  "RackController GET" should {
    "render the rack page from a new instance of controller" in {
      val controller = new RackController(stubControllerComponents(), rack, gpu)
      val result = controller.all().apply(FakeRequest(GET, "/api/all"))


      status(result) mustBe OK
      contentType(result) mustBe Some("application/json")
      contentAsString(result) must include("{ \"profitPerGpu\" }")
    }
  }
}

I have this error saying the no implementations of play.api.db.slick.DatabaseConfigProvider was found. I already tried to remove jdbc from my build.sbt but it didnt work.

Does anyone have an idea?

Thanks, Felipe
