DESCRIPTION:

Stubbing and mocking that isn't painful, fanciful, and doesn't inspire any sort of contempt or bitterness.

FEATURES/PROBLEMS:

  • 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?"
  • Proxying objects.

    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

SYNOPSIS:

# 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")

NOTES:

  • Be sure you call super in teardown if you create your own teardown methods. Otherwise your mocks won't get verified!

REQUIREMENTS:

  • Test::Unit (batteries included with Ruby)

INSTALL:

$ gem sources -a http://gems.github.com
$ sudo gem install jeremymcanally-stump

ACKNOWLEDGEMENTS:

  • 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.
