Stubbing and mocking that isn't painful, fanciful, and doesn't inspire any sort of contempt or bitterness.
Stubbing right on the object.
# Returns 'hey!' MyClass.stub!(:thing, :return => "hey!") # Returns nil your_object.stub!(:hello)
Pure stub objects.
my_stub = stub(:thing, :return => "dude, a thing!") my_stub.thing # => "dude, a thing!"
Mocking right on the object.
my_object = "things are fun" my_object.mock!(:fancy, "ooo fancy!") my_object.fancy # => "ooo fancy!"
Pure mock objects.
my_mock = mock(:hello, :return => "what fun is this?") my_mock.hello # => "what fun is this?"
class Greeting def bonjour "Bonjour!" end end greet_me = Greeting.new greet_me.proxy!(:bonjour) greet_me.bonjour # => "Bonjour!" greet_you = Greeting.new greet_you.proxy!(:bonjour) # finish test... # ! Unmet expectations: #<Greeting:0x371d24> expected hello
# Stub class methods MyClass.stub!(:thing, :return => "hey!") # Stub method on object your_object.stub!(:my_method) # Stub method on object, requiring parameters my_object.stub!(:other_method) do |arg1, arg2| puts arg1 puts arg2 end # Mock method on object MyClass.mock!(:my_method, :return => "hehe") # Mock method on object, requiring parameters my_obj.mock!(:hehe, :return => nil) do |arg1, arg2, arg3| # Fun party! end # Sets expectation it will receive a method, calling the real method MyClass.proxy!(:the_method) # Returns static value but still has side effects of real method call MyClass.proxy!(:that_method, :return => "poop")
Be sure you call super in teardown if you create your own teardown methods. Otherwise your mocks won't get verified!

Thanks to Jim Weirich for Flexmock, David Chelmisky et. al. for RSpec's mocking stuff, and Brian Takita for rr. All of those things fed into stump.
BIG thanks to Nathan Sutton (fowlduck) for helping me work through how to get proxy! to work with ActiveRecord/method_missing.
