Efficient Tests for modern Full-Stack Web Applications with JSON in the middle


Iā€™m trying to come up with efficient tests design for the full stack application which combines both client (web ui) and server in one, communicating via JSON API.

I come up with a sample app which is Ruby on Rails:

And I keen to hear more from others experiences :slight_smile:


tl;dr The key difference comparing to common approaches is that we treat rails models as a resource documents and use them to assert both UI and API endpoints, without exposing serialization details (JSON Schema) into the tests. As a result it simplify tests, reduces coupling, duplication and expresses architecture.
