All, Brian Takita has been contributing to a stubs branch to support stubbing and partial mocking on Modules (and therefore classes). I tweaked the syntax a bit and merged it into the trunk, so you can update from the trunk and check out the new stubbing/mocking love. If you prefer to wait for a release, there should be one coming soon-ish (I''m aiming for later this week). As Brian pointed out in an earlier email, partial mocking is generally somewhat of a last resort, but it is very useful in some cases - like spec''ing rails controllers that interact with rails model classes: #stubbing - when you don''t care about verification Person.stub!(:find).and_return(@person) #partial mocking: when you do care about verification Person.should_receive(:find).with("1").and_return(@person) This is not yet documented on the website - that will be happening over the next few days. Also, this does not preclude our slightly longer term goal of supporting the integration of other mocking/stubbing frameworks. That is in the works as well. Enjoy! And thanks to Brian for the excellent contributions. Cheers, David
