Have you looked at using Test Credentials? These are a special set of credentials and magic phone numbers that you can use to tell Twilio via the REST API to emulate things like making an outbound phone call. Using the magic phone numbers you can get Twilio to return specific responses (like trying to dial an international phone number without the right permissions).

For testing webhook endpoints (the URL's in your webhook that Twilio is going to make its HTTP requests to), you can use the same testing techniques you would to test a normal web app.
