OneServerPerTestWithComponents

trait OneServerPerTestWithComponents extends BaseOneServerPerTest with WithApplicationComponents with FakeApplicationFactory

An extension of BaseOneServerPerTest providing Compile-time DI.

Trait that provides a new Application and running TestServer instance for each test executed in a ScalaTest Suite

This TestSuiteMixin trait overrides ScalaTest's withFixture method to create a new Application and TestServer before each test, and ensure they are cleaned up after the test has completed. The Application is available (implicitly) from method app. The TestServer's port number is available as port (and implicitly available as portNumber, wrapped in a PortNumber).

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

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

import org.scalatestplus.play.PlaySpec
import org.scalatestplus.play.components.OneServerPerTestWithComponents
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 OneServerPerTestWithComponents {

  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 = Configuration("foo" -> "bar", "ehcacheplugin" -> "disabled").withFallback(context.initialConfiguration)
  }

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