Currently, what you're doing is checking that the Widget model returns
the correct widgets. If you want to isolate your controller spec from
the model, you must stub or mock the model method call in the action.
Example:
it "..." do
widget = mock_model(Widget)
Widget.should_receive(:all).and_return([widget])
get :index
assigns[:widgets].should include(widget)
end
To check that Widget.all does indeed return the correct widgets, I
would spec that behaviour in the Widget model spec.
Hope that helps.
