Provided trait TestingFintrospectRoute can be used to unit test your routes, as in the simple example below:

object EchoRoute {
  val route = RouteSpec().at(Method.Get) / Path.string("message") bindTo( (message: String) => Service.mk {
    req: Request => Future(PlainText.ResponseBuilder.OK(message))

class EchoRouteTest extends FunSpec with Matchers with TestingFintrospectRoute {

  override val route = EchoRoute.route

  describe("Echo") {
    it("bounces back message") {
      responseFor(Request("hello")).contentString shouldBe "hello"

test http server

The TestHttpServer is convenient for attaching routes to during development, or can be used as a scaffold to provide automatically generated fake servers for downstream dependencies - simply complete the stub implementation of the server-side and fire it up. This works especially well if you are utilising custom serialisation formats (such as one of the auto-marshalling JSON libraries), as there is absolutely no marshalling code required to send back objects over the wire from your stub.

val route = RouteSpec().at(Get) / "myRoute" bindTo(() => Service.mk {r => Future(Response(Status.Ok))})
new TestHttpServer(9999, route).start()
