I''ve added a method to the mock class that makes it pretty easy to stub associations in rails. I''ve been using it for awhile and it seems to cut down on a lot of setup code for the controller and model specs that use associations. #before @person = mock_model(Person) posts = mock(''post_proxy'') posts.stub!(:build).and_return(mock_model(Post, :save => true))

Hi this is my first post. I am trying to run a simulation for a computer playing Von Neumann poker and adjusting it's expectation of an opponent's behavior according to how the opponent plays. This program involves random generation of "hands" and shifting of parameters. However, when I run the code, no errors come up, but the program doesn't do anything. Could someone

I''m trying to jump on the TDD/BDD bandwagon, but am having trouble understanding how i should mock my user. The user has a habtm relationship to a roles model (acl_system2 plugin), but I''m not sure how to tell rspec about a model. My code: describe UsersController do integrate_views before(:each) do @user = mock_model(User)

I have a weird problem going on. All of sudden, records for a certain model will not save with #save Please take a look at this: >> p = Payment.new(:payment_reason_id => 1, :payment_method_id => 1, :date => Date.today, :amount => ''5.00'', :payable => Student.find(608)) => #<Payment id: nil, school_id: nil, payment_reason_id: 1, payment_method_id: 1,

Hello, I have this cucumber step definition: Given /^the site has pages "(.+)" and "(.+)"$/ do | page_1, page_2 | Page.create :title => page_1 if Page.find_by_title(page_1).nil?
