RSpec book help; why won't this stub method work?

[David Zhang]

Subscription model--------------------------------------------

class Subscription < ActiveRecord::Base

  has_one :user

  def can_send_message?

    if user.sent_messages.count < limit

      true

    else

      false

    end

  end

end

Subscription model spec--------------------------------------------

require 'spec_helper'

describe Subscription do

  describe "#can_send_message?" do

    before(:each) do

      @subscription = Subscription.new(:limit => 10)

      @zach = User.create! :subscription => @subscription

    end

    context "when a user has not reached the subscription limit for the month" do

      it "returns true" do

        @zach.sent_messages.stub(:count).and_return(9) # this isn't working

        @subscription.can_send_message?.should == true

      end

    end

    context "when a user has reached the subscription limit for the month" do

      it "returns false" do

        @zach.sent_messages.stub(:count).and_return(10) # this isn't working

        @subscription.can_send_message?.should == false

      end

    end

  end

end

=================

When I run rspec spec for these examples, the first example passes because user.sent_messages.count is ZERO.

The second example fails... Any ideas why?

count is a class method, so maybe you should try stubbing it on the Message class

[David Zhang]

That did it! Thanks - I didn't know class methods required that.

Message.stub(:count).and_return(9)
