Awesome. I totally get it, but is that how you're always supposed to spec out associations and all the methods that go with an association like "create" and such? I'm interested in that because I'm specing a lot of code that deals heavily with code that has associations going on, yet none of the examples of RSpec use I come across have anything about associations and RSpec. I don't imagine they'd be handled too differently, but it's just something wondered about.
Right now, I'm testing and building up a controller and so far my tests have been passing as long as I don't run into any examples that involve associations. This code, for example, has been giving me a few issues: # my users_controller_spec.rb (or at least, the relevant part) describe UsersController do fixtures :users before(:each) do @tiffani = users(:tiffani) @users = [EMAIL PROTECTED] @users.stub!(:build).and_return(@tiffani) @mock_account = mock_model(Account, :users => @users, :save => true) end describe "when creating a User" do it "should return the registration form for adding a User on GET new" do User.should_receive(:new).once get :new end it "should render the new User registration form on GET new" do get :new response.should render_template("users/new") end it "should create a new User and then redirect to that User's profile on POST create" do @mock_account.should_receive(:new) post :create, :new_user => { :first_name => @tiffani.first_name, :last_name => @tiffani.last_name, :email_address => @tiffani.email_address } end it "should redirect to users/new when User is setup with invalid data" end # ... end And in users_controller.rb: def create @new_account = Account.new(params[:account]) @new_user = @new_account.users.build(params[:new_user]) respond_to do |wants| if @new_account.save flash[:notice] = "Welcome, #{ @new_user.first_name }!" wants.html { redirect_to(user_url(@new_user)) } else wants.html { render :action => "new" } end end end When I run the tests the third test fails and RSpec complains that "Mock 'Account_1003' expected :new with (any args) once, but received it 0 times" I'm confused about that since I am calling Account.new in the create method on the controller. What's really wrong here? Thanks in advance for answering my RSpec questions! :D --Tiffani AB On Thu, Jul 3, 2008 at 9:09 PM, Mikel Lindsaar <[EMAIL PROTECTED]> wrote: > On Fri, Jul 4, 2008 at 8:32 AM, Tiffani Ashley Bell > <[EMAIL PROTECTED]> wrote: > > Hi everybody, > > Hi Tiffany, welcome to Rspec > > > I was reading the Typo source code, however, and came across some code > that > > I didn't know exactly how it worked.
