trait OneServerPerSuiteWithComponents extends BaseOneServerPerSuite with WithApplicationComponents with FakeApplicationFactory

An extension of BaseOneServerPerSuite providing Compile-time DI.

Trait that provides a new Application and running TestServer instance per ScalaTest Suite.

By default, this trait creates a new Application for the Suite according to the components defined in the test, this is made available via the app field defined in this trait and a new TestServer for the Suite using the port number provided by its port field and the Application provided by its app field. If your Suite needs a different port number, override port.

This TestSuiteMixin trait's overridden run method calls start on the TestServer 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 and to the port number provided by port under the key org.scalatestplus.play.port. This allows any nested Suites to access the Suite's Application and port number as well, most easily by having the nested Suites mix in the ConfiguredServer trait. On the status returned by super.run, this trait's overridden run method registers a call to stop on the TestServer to be executed when the Status completes, and returns the same Status. This ensure the TestServer will continue to execute until all nested suites have completed, after which the TestServer 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 TestServer, 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 OneServerPerSuite and declares the nested Suites. Annotate the nested suites with @DoNotDiscover and have them extend ConfiguredServer. Here's an example:

import org.scalatest.{ DoNotDiscover, Suites, TestSuite }
import org.scalatestplus.play.components._
import org.scalatestplus.play.{ ConfiguredServer, 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 OneServerPerSuiteWithComponents 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 ConfiguredServer {
  "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 ConfiguredServer

@DoNotDiscover class RedSpec extends PlaySpec with ConfiguredServer

@DoNotDiscover class BlueSpec extends PlaySpec with ConfiguredServer {

  "The NestedExampleSpeccc" 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!")
    }
    "provide an actual running server" in {
      import java.net._
      val url = new URL("http://localhost:" + port + "/boum")
      val con = url.openConnection().asInstanceOf[HttpURLConnection]
      try con.getResponseCode mustBe 404
      finally con.disconnect()
    }
  }
}

    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.
