[rspec-users] experimenting with stub in irb with RSpec2

In class, to give people a feel for how stubs work, I used to do this
with rspec 1.x:

sarah:~$ gem list rspec

*** LOCAL GEMS ***

rspec (1.3.0)
rspec-rails (1.3.2)
sarah:~$ ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]
sarah:~$ irb
>> require 'spec'
=> true
>> require 'spec/mocks'
=> true
>> Time.stub!(:now).and_return(10,20)
=>
#<Proc:0x00000001015936f0@/Library/Ruby/Gems/1.8/gems/rspec-1.3.0/lib/spec/mocks/message_expectation.rb:61>
>> Time.now
=> 10
>> Time.now
=> 20
>> Time.now
=> 20
>>

I can't figure out how to do that in RSpec 2.  Here's what I've tried:


sarah:~$ gem list rspec

*** LOCAL GEMS ***

rspec (2.0.1, 2.0.0, 2.0.0.beta.22)
rspec-core (2.0.1, 2.0.0, 2.0.0.beta.22)
rspec-expectations (2.0.1, 2.0.0, 2.0.0.beta.22)
rspec-mocks (2.0.1, 2.0.0, 2.0.0.beta.22)
rspec-rails (2.0.1, 2.0.0, 2.0.0.beta.22)
sarah:~$ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10.4.0]
sarah:~$ irb
ruby-1.8.7-p302 > require 'rspec'
 => true
ruby-1.8.7-p302 > require 'rspec/mocks'
 => false
ruby-1.8.7-p302 > require 'rspec-mocks'

ruby-1.8.7-p302 > Time.stub!(:now).and_return(10,20)
NoMethodError: undefined method `stub!' for Time:Class

Can anyone give me a hint?

Thanks in advance,
