Here is a simple example using Vert.x with Groovy,

//----------------------------------------------------------------------------------------------------
@Test
void pingServer() {
  HttpServerOptions options = new HttpServerOptions(port: 7575)
  HttpServer server = Vertx.vertx().createHttpServer(options).requestHandler { request ->
    request.response().putHeader('Content-Type', "text/plain").setStatusCode(200).end("test")
  }
  server.listen()

  RESTClient client = new RESTClient("http://localhost:7575", "text/plain")
  def response = client.get(path: "/")

  assertEquals(200, response.status)

  server.close()
}
//---------------------------------------------------------------------------------------------------- 

IMO this is a lot easier than relying on an external server. And it is much simpler to control the server behavior.
