trait OneAppPerSuiteWithComponents extends BaseOneAppPerSuite with WithApplicationComponents with FakeApplicationFactory

An extension of BaseOneAppPerSuite providing Compile-time DI.

Provides a new Application instance per ScalaTest Suite.

By default, this trait creates a new Application for the Suite according to the components defined in the test.

This TestSuiteMixin trait's overridden run method calls Play.start, passing in the Application provided by app, before executing the Suite via a call to super.run. In addition, it places a reference to the Application provided by app into the ConfigMap under the key org.scalatestplus.play.app. This allows any nested Suites to access the Suite's Application as well, most easily by having the nested Suites mix in the ConfiguredApp trait. On the status returned by super.run, this trait's overridden run method registers a call to Play.stop to be executed when the Status completes, and returns the same Status. This ensure the Application will continue to execute until all nested suites have completed, after which the Application will be stopped.

Here's an example that demonstrates some of the services provided by this trait:

import org.scalatestplus.play.PlaySpec
import org.scalatestplus.play.components.OneServerPerSuiteWithComponents
import play.api._
import play.api.mvc.Result
import play.api.test.Helpers._
import play.api.test.{FakeRequest, Helpers}

import scala.concurrent.Future

class ExampleComponentsSpec extends PlaySpec with OneServerPerSuiteWithComponents {

  override def components: BuiltInComponents = new BuiltInComponentsFromContext(context) with NoHttpFiltersComponents {

    import play.api.mvc.Results
    import play.api.routing.Router
    import play.api.routing.sird._

    lazy val router: Router = Router.from({
      case GET(p"/") => defaultActionBuilder {
        Results.Ok("success!")
      }
    })

    override lazy val configuration: Configuration = context.initialConfiguration ++ Configuration("foo" -> "bar", "ehcacheplugin" -> "disabled")
  }

  "The OneServerPerSuiteWithComponents trait" must {
    "provide an Application" in {
      import play.api.test.Helpers.{GET, route}
      val Some(result): Option[Future[Result]] = route(app, FakeRequest(GET, "/"))
      Helpers.contentAsString(result) must be("success!")
    }
    "override the configuration" in {
      app.configuration.getOptional[String]("foo") mustBe Some("bar")
    }
  }
}

If you have many tests that can share the same Application, and you don't want to put them all into one test class, you can place them into different Suite classes. These will be your nested suites. Create a master suite that extends OneAppPerSuiteWithComponents and declares the nested Suites. Annotate the nested suites with @DoNotDiscover and have them extend ConfiguredApp. Here's an example:

import org.scalatest.{DoNotDiscover, Suites, TestSuite}
import org.scalatestplus.play.components.OneAppPerSuiteWithComponents
import org.scalatestplus.play.{ConfiguredApp, PlaySpec}
import play.api._
import play.api.mvc.Result
import play.api.test.Helpers._
import play.api.test.{FakeRequest, Helpers}

import scala.concurrent.Future


class NestedExampleSpec extends Suites(
  new OneSpec,
  new TwoSpec,
  new RedSpec,
  new BlueSpec
) with OneAppPerSuiteWithComponents with TestSuite {
  // Override fakeApplication if you need an Application with other than non-default parameters.
  override def components: BuiltInComponents = new BuiltInComponentsFromContext(context) with NoHttpFiltersComponents {

    import play.api.mvc.Results
    import play.api.routing.Router
    import play.api.routing.sird._

    lazy val router: Router = Router.from({
      case GET(p"/") => defaultActionBuilder {
        Results.Ok("success!")
      }
    })

    override lazy val configuration: Configuration = context.initialConfiguration ++ Configuration("ehcacheplugin" -> "disabled")

  }
}

// These are the nested suites
@DoNotDiscover class OneSpec extends PlaySpec with ConfiguredApp {
  "OneSpec" must {
    "make the Application available implicitly" in {
      def getConfig(key: String)(implicit app: Application) = app.configuration.getOptional[String](key)

      getConfig("ehcacheplugin") mustBe Some("disabled")
    }
  }

}

@DoNotDiscover class TwoSpec extends PlaySpec with ConfiguredApp

@DoNotDiscover class RedSpec extends PlaySpec with ConfiguredApp

@DoNotDiscover class BlueSpec extends PlaySpec with ConfiguredApp {

  "The NestedExampleSpec" must {
    "provide an Application" in {
      import play.api.test.Helpers.{ GET, route }
      val Some(result): Option[Future[Result]] = route(app, FakeRequest(GET, "/"))
      Helpers.contentAsString(result) must be("success!")
    }
  }
}

    Invokes Play.start, passing in the Application provided by app, and places that same Application into the ConfigMap under the key org.scalatestplus.play.app to make it available to nested suites; calls super.run; and lastly ensures Play.stop is invoked after all tests and nested suites have completed.

    testName

    an optional name of one test to run. If None, all relevant tests should be run. I.e., None acts like a wildcard that means run all relevant tests in this Suite.

    args

    the Args for this run

    returns

    a Status object that indicates when all tests and nested suites started by this method have completed, and whether or not a failure occurred.
