	request := make(chan *http.Request)
	errors := make(chan error)

	if binary.Size(payload) > 0 {
		req, err := http.NewRequest(method, url, bytes.NewBuffer(payload))
		go func() {

			errors <- err
		}()
	} else {
		req, err := http.NewRequest(method, url, nil)
		go func() {
			request <- req

		}()
	}

	if <-errors != nil {
		logrus.Error(<-errors)
	}

	rr := httptest.NewRecorder()
	handler.ServeHTTP(rr, <-request)

	return rr
