Mocking the connect function of nats

[chethan-b-hpe]

Any one having idea on how we can mock the nats.Connect function I tried in many ways but still its not working,
sample snippet , I want to mock Connect function of nats here :

`	for retries = 0; retries < maxAttempts; retries++ {
		log.Infof("connecting to: %v", url)
		conn, err = natsgo.Connect(url, nats.Timeout(200*time.Millisecond))
		if err == nil {
			break
		}

		log.Errorf("Error occurred while connecting to NATS stream. Err :%v Retry attempt %d in %d seconds", err, retries+1, backoffTime/time.Second)
		backoffTime *= 2
		time.Sleep(backoffTime)
	}`
