Unit testing mocking Models and/or ResultSet's

Is there a way to mock or a complete Unit Test example for an application using Phalcon PHP?

I'm developing a RestfulAPI but I'm above many problems to mock and organizing test. There isn't a visible and complete example in documentation. For example, I have a resource called "areas", by the request "GET /areas", at Controller I call Areas::find(). How to mock it? How to mock multiple models used inside the same Controller? My application has many validation and business logic and is necessary apply unit testing.
