Akka Http Test Gzip Response

So, I have a set of Akka Http routes written in scala. Which looks like this

val route: Route = {
  handleRejections(PrimaryRejectionHandler.handler) {
    handleExceptions(PrimaryExceptionHandler.handler) {
      cors() {
        encodeResponseWith(Gzip) {
          pathPrefix("v1") {
            new v1Routes().handler
          } ~
            path("ping") {
              complete("pong")
            }
        }
      }
    }
  }
}

Now I want to test this using scala-test and akka testkit.

class HttpRouteTest extends WordSpec with Matchers with ScalatestRouteTest {

  "GET /ping" should {

    "return 200 pong" in new Context {
      Get("/ping") ~> httpRoute ~> check {
        responseAs[String] shouldBe "pong"
        status.intValue() shouldBe 200
      }
    }
  }

  trait Context {
    val httpRoute: Route = new HttpRoute().route
  }

}

Now since, I am encoding my responses with gzip in the route, the test is getting gibberish when it's trying to convert to string. As a result the test does not pass.

Is there any solution to this? Thanks in advance.
