RSpec对ActiveMailer模型的测试调用

Question

Hey everyone I am trying to get Rspec to test if an action calls a specific method in a model I have which inherits from ActiveMailer but have been having no luck. So as a quick mockup I have the following scenario. Model UserNotifier:

class UserNotifier < ActionMailer::Base  
  def foobaz
  end
end

Controller Password Controller:

class PasswordsController < ApplicationController

def foobar
  UserNotifier.foobaz
end

And the spec:

 describe "GET 'foobar'" do

   it "should call the UserNotifier foobaz method" do
     UserNotifier.should_receive(:foobaz)
     get :foobar
   end
 end

but I always end up with this failure:

1) PasswordsController GET 'foobar' should call the UserNotifier foobaz method
 Failure/Error: UserNotifier.should_receive(:foobaz)
   (<UserNotifier (class)>).foobaz(any args)
       expected: 1 time
       received: 0 times

Can anyone enlighten me as to why RSpec does not register that the UserNotifier.foobaz method is being called?

Answer 1

Answered in the comments by Ryan Bigg. Ended up being a before_filter which was causing the method to never be run

Answer 2

I've got exactly the same problem, but it's not due to any filters (not using any). One difference is that I'm calling an action on ApplicationController, though I don't see why that would matter. The foobaz method definitely gets called, given that the rspec run includes output I insert there, yet Rspec doesn't see the call. Any other ideas for what could be wrong?
