rspec users - Dec 2008 - The RSpec way of doing this? Need help on validating block

Hello, I''m back again with more questions about mocks and how to do
good
testing in general. Let''s say I''m writing this EmailSender
class and I
want to make it totally awesomely tested with RSpec. Here''s how far
I''ve
gotten so far:

require ''net/smtp''

class EmailSender
  def send_email
    mailer.start(''your.smtp.server'', 25) do |smtp|
      smtp.send_message("Yay! You got an email!", ''your at
mail'',
''other at mail'')
    end
  def

  def mailer
    Net::SMTP
  end
end

describe EmailSender do
  it "Should use Net::SMTP to send email"
    es = EmailSender.new
    es.mailer.should == Net::SMTP
    MockSMTP = mock("Net::SMTP")
    def es.mailer
      MockSMTP
    end
    MockSMTP.should_receive(:start).with(''your.smtp.server'',
25)
    #but, er...wha?
  end
end

So - not sure how to validate the part where "send_message" is called.
Is there a recommended way of doing this?

Yikes, left out the all-important call:

>   it "Should use Net::SMTP to send email"
>     es = EmailSender.new
>     es.mailer.should == Net::SMTP
>     MockSMTP = mock("Net::SMTP")
>     def es.mailer
>       MockSMTP
>     end
>    
MockSMTP.should_receive(:start).with(''your.smtp.server'', 25)
>     #but, er...wha?
      es.send_email
>   end
> end
Sorry about that.

       mock_smtp = mock("smtp")
      
MockSMTP.should_receive(:start).with(''your.smtp.server'',
25).and_yield(mock_smtp)
       mock_smtp.should_recieve(:send_message).with("Yay! You got an
