.ensure_working_CRUD(model, attr) ⇒ Object

Enables quick tests to ensure that the basic CRUD functionality is working correctly for a Model

let(:m) { User.make }

ensure_working_CRUD(User, :username)

NOTE!

  • the passed ‘_model` argument must be the actual Model class and NOT a string or symbol

  • the passed attribute ‘_attr` must be a String attribute or the tests will fail

DEPENDENCIES

this test depends upon being able to create a new model instance for each test via using Sequel Factory’s ‘#make()` method
