can mocks be created with default attribute values? I am not certain what this question really mean. Two possibilities:

  1. if an object t=Movie.find(10), and then if I say m=mock(t), does m automatically inherit all the attribute values of t?

  2. is there a way to create a mock object with default attributes such that we can clone it everytime when we use it without going thru series stubs to "initialize" those attributes?

Thanks for your help.

    When it comes to 1) It does not have a sense. If inside the test you have an access to the real object through Movie.find(10) you don’t have to use mocks. Assuming that you’re using rspec_mocks and you’re going to write an assertion that particular method was called, you could simply write:

    t = Movie.find(10)
t.should_receive(:foo)

    Also check this out: https://www.relishapp.com/rspec/rspec-rails/v/2-11/docs/mocks/mock-model
    and this https://www.relishapp.com/rspec/rspec-rails/v/2-11/docs/mocks/stub-model

    Very useful helpers for mocking AR/Mongoid and other models in specs.

    Along with factory_girl you could set an attributes on this mocks, for example movie = mock_model(Movie, FactoryGirl.attributes_for(:move))
