 This approach to testing has one caveat: the responses are not type-safe. That is, the stub backend cannot match on or verify that the type of the response body matches the response body type requested.
 
+Another way to specify the behaviour is passing a response monad to Stub. It is useful if you need to test scenario with slow server, when response should be not returned immediately but after some time.
+Example with Futures: ::
+
+  implicit val testingBackend = SttpBackendStub(new FutureMonad()).whenAnyRequest
+    .thenRespondWithMonad(Future {
+      Thread.sleep(5000)
+      Response(Right("OK"), 200, "", Nil, Nil)
+    })
+
+  val respFuture = sttp.get(uri"http://example.org").send()
+  // responseFuture will complete after 10 seconds with "OK" response
